* [editor-core] share the blob hash and the doc-vs-file rule
The git blob hash and the rule that decides whether a file is a doc or a binary
file both have to reach the same answer in every service that writes to history,
so they move into overleaf-editor-core rather than being spelled out again on
each side.
blob_utils takes over lib/blob_string_length.js: hashing and the string-length
rule answered two halves of the same question -- what history needs to know
about content before it can store it -- and each carried the same warning about
staying off index.js, which is bundled for the browser. One module states it
once, and blobForFile joins them, describing content on disk as the blob it
amounts to. The hashing functions are flat rather than a namespace of their own:
in a module that also holds the string-length rule, a bare fromStream says
nothing about what it makes. history-v1's blob store and recover_zip follow the
module to its new name.
file_type_detector holds the doc-vs-file rule, Node-only and deep-imported for
the same reason. It takes textExtensions, editableFilenames and maxDocLength as
configuration rather than reading settings: the limit is web's 2 MiB and not
editor-core's own 3 MiB, and the surrogate check covers both halves of a pair
where editor-core's covers the high half.
buildSetContentOperations' test spelled the blob header out for itself, with the
separator as a literal NUL byte, which had git reading the file as binary. It
hashes through blobHashFromString now, so it does not spell the header at all.

* [editor-core] name the client a change came from on the origin itself
`EditorOrigin` carried an `editorId` that only an editor change could have. What
the id is for -- recognising a change again, so history does not apply a resend
twice and the client does not apply its own change back -- is a property of the
client that submitted it rather than of what it did, so it moves onto `Origin` as
an optional `historyClientId` and `EditorOrigin` goes.
- `Origin` takes `(kind, historyClientId)` and answers `getHistoryClientId()`;
`dropHistoryClientId()` is what the chunk store uses to strip the id from all
but a client's latest change, which now leaves the rest of the origin alone --
a restore that a client submitted stays a restore.
- `toRaw` is built a layer at a time: the base writes the kind and the id, a
subclass spreads that and adds the fields it owns.
- The named kinds are their own schemas and discriminate on `kind`, so a payload
claiming one is checked against that shape and the error says what it got
wrong. The catch-all cannot join them -- its kind is any string -- so it sits
alongside and is refined to refuse the named kinds, which it used to swallow:
`{kind: 'restore'}` validated as a kind and nothing else, then read back as a
restore that recorded nothing about what it restored.
- `lib/origin/*.js` gains `// @ts-check`. Without it the annotations in there
were decorative: the lazily required subclasses were `any`, so nothing handed
to them was checked, and `fromRaw` narrows with `in` to drop the catch-all
variant, which a kind check cannot.
The callers that stamp the id -- real-time's handshake flag, web's applyChange
body -- come with the rest of the branch.

* [editor-core] recognise a change a writer that is not an editor placed
The counterpart of `isSameEditorChange` for writers that are not an editor
client: an integration that commits a batch on a user's behalf has to recognise
that batch coming back, because a lost response does not say whether the commit
landed and resubmitting one that did applies its removes twice.
It compares the same three fields, and for the same reason -- a rebase rewrites a
change's operations but leaves its origin, authors and timestamp alone -- with
the timestamp compared as a point in time rather than as a string, so that two
spellings of the same instant cannot read as different changes. github-sync is
the first caller, and comes with the rest of the branch.

* [editor-core] load an editable file's content, or say it has none
Only an editable file has content: any other kind is bytes addressed by hash, and
hollow data records the size of content it does not have. Both answer
`getContent()` with null, so every caller that wants the content of a doc loaded
it, checked the data's class, and reached for its own error when the check failed.
`File#loadEager` does that once and answers the data that always has the content.
`buildSetContentOperations` takes a `ReadWriteBlobStore` -- everything but
looking a blob up by hash, which is all it takes to build operations over content
-- so a caller holding a store that cannot answer `getBlob` can still use it. Its
metadata argument is `FileMetadata` rather than `Object`, which is what the schema
already says a file's metadata is.

* [editor-core] say that a pair of operations that do not fit is unprocessable
compose and transform threw a bare Error when the two operations do not describe
the same content. Everything that answers a client for these -- history-v1's
import routes, the git-bridge push, project-history's resync -- decides on
UnprocessableError, so a bare Error reached them as an internal failure: a 500,
which reads as worth retrying, for a pair that fails the same way every time.
A client that resubmits on a 500 resubmits forever.
The guards that cannot be reached through the API keep their bare Error: a
TextOperation composed with something that is not one, and the branch whose
message says it should not happen.

* [history-v1] hash blobs with the rule editor-core holds
storage/lib/blob_hash.js was a bluebird-era implementation of the same git blob
hash editor-core holds, exported from the storage barrel and used across the
storage layer, the api and the tests. All of it reads the shared rule now, and
the test that existed only to check the copy is gone -- editor-core's suite
covers the same non-ASCII case.

The hash of empty content is a property of the content rather than of anything
stored: every project's empty file has it, whether or not a blob was ever written
under it, and a file may reference it before anything has. Eight blob stores were
each paying a lookup -- a database query, an HTTP request, a read of a cache that
offline mode may be the only thing standing in for -- to be told what the hash
already says, and clsi had already reinvented the answer on its own.
overleaf-editor-core gains BlobStoreBase, which answers getString for that hash
and delegates the rest to the fetchString its subclasses provide. getObject comes
with it: four stores spelled out the same JSON.parse of getString, and a fifth
wrapped it in a log line.
Adopted by history-v1's BlobStore, BackupBlobStore, HashCheckBlobStore and
recover_zip's RecoveryBlobStore, by project-history's BlobStore, by clsi's
BlobStore, and by web's HistoryBlobStore, SimpleBlobStore and FrontendBlobStore.
history-v1 keeps its own answers in getStream, getBlob and getBlobs, which no
other store implements. Writing and copying a blob are untouched, so a project
that wrote empty content still has a blob for it and a read answers the same
either way.
Two paths could not handle a project holding a tracked change or a comment at
all. Loading such a file needs the ranges blob its rangesHash points at, and
hashing one again needs to write it back, so a store missing getObject or
putObject fails outright:
- recover_zip died on `blobStore.getObject is not a function`, making every such
project unrecoverable. The test covering it asserts a tracked delete is absent
from the zip, which the script already asked for and never reached.
- GET /projects/:project_id/latest/hashed_content returned 500 from the same
cause, then would have hit a missing putObject in snapshot.store.
HashCheckBlobStore becomes a class over the base and gains putObject.

* [editor-core] share the pieces the editor, real-time and history-v1 all need
Project-level history-OT has the browser, real-time and history-v1 all reason
about the same changes, so the rules they reason with move into the shared
library rather than being reimplemented on each side.
- `origin/editor_origin.js` plus `EDITOR_ORIGIN_KIND` and its schema entry: the
origin an editor client's change carries, holding the editorId that scopes a
change's timestamp.
- `change_identity.js`: how a submission is recognised when it comes back, so a
resend of a change that already landed is deduplicated rather than applied
twice.
- `rebase.js`: transforming a change onto concurrent ones, in the same order on
both sides, which is what lets the server acknowledge a change with only the
version it landed at.
- `text_file_defaults.js`: the doc-vs-file extension lists, now read from here
by web's settings instead of being spelled out again.
- `blob_string_length.js`: the string length of a blob, used by history-v1's
blob store and by web when it writes an uploaded file into history.
- `file_tree_diff.js`: file-tree operations to a diff, used by
project-history's FileTreeDiffGenerator.
- `Blob.EMPTY_HASH`, so callers can answer for the empty blob without storing
it.

* [project-history] build the file-tree diff with the shared helper
FileTreeDiffGenerator's hand-rolled walk over add/edit/move/delete operations
becomes a call to `buildFileTreeDiff` from overleaf-editor-core, so the editor
and project-history read a file-tree change the same way. Adds the unit tests
the decaffeinated original never had.

* [web] read the editable-file lists from overleaf-editor-core
web's settings spelled out the text extensions and editable filenames that
decide whether a file becomes a doc, and every other service that has to make
that call carried its own copy. The lists now live in overleaf-editor-core and
web builds settings.textExtensions and settings.editableFilenames from them,
keeping the ADDITIONAL_TEXT_EXTENSIONS override for Server CE/Pro on top.

* [history-v1] read a blob's string length from overleaf-editor-core
Two copies of getStringLengthOfFile lived here, the one in recover_zip.js
carrying a TODO asking for exactly this. Both now import the shared
implementation, which the blob store keeps re-exporting for backupArchiver.
