Stripping forwarding headers kept our IP and chain out of reach, but the
User-Agent went through untouched. Clients that fell back to their own name
("crawlkit-roles", "crawlkit-virk", ...) tied all ten exits together as one
actor, and one missing UA meant Go-http-client. The proxy now overwrites the
UA on every request (WEIRCON_USER_AGENT, default current Firefox) and the
egress prober uses the same string.
Also dropped: From, Sec-Ch-Ua* (would contradict a Firefox UA) and any
X-Weircon-* by prefix. New end-to-end test drives the whole handler and
checks what the target actually receives.

Keep the N always-on tunnel slots fixed but let each slot's WireGuard config
rotate through a larger pool, so a 10-concurrent provider cap (e.g. Proton) can
still cycle 50-100 profiles.
- lxc/rotate.sh + weircon-rotate.{service,timer}: round-robin one slot at a
time through wg-pool/, repointing a symlink and restarting only that slot.
- service: proxyManager tracks per-slot in-flight + drain/undrain state; a
localhost admin server (WEIRCON_ADMIN_LISTEN) lets rotate.sh drain a slot
before teardown and warm it back in after, so no request is routed to a
tunnel mid-rotation. Slots self-heal if undrain never arrives.
- GET /status: poll-friendly JSON of per-slot egress IP/state plus inferred
next-rotation slot + ETA, fed by a background egress-IP prober.
- docs + env examples for all new knobs.
