cdd6b41261 fix(concurrency): release slot on subprocess SIGTERM failure (#40)
Per forensic analysis in #37, the timeout handler at server.mjs:471
called `proc.kill('SIGTERM')` without decrementing the concurrency
counter (`stats.activeRequests`). If the subprocess was stuck in a
syscall (e.g. MCP I/O) and ignored SIGTERM, its slot was not freed
until — and only if — the `proc.on('close')` handler eventually fired
after the 5s SIGKILL escalation successfully reaped the child.
Real-world observation (#37) shows 3 stuck claude subprocesses running
20 minutes to 2h 45m, exhausting the 8-slot pool and returning
`500 concurrency limit reached (8/8)` on every subsequent request.

Fix: attach `cleanup` to `proc.once('exit', ...)`. The 'exit' event
fires before 'close' and runs on every termination path — normal
completion, error, SIGTERM, SIGKILL, crash — even if stdio pipes
stay open. `cleanup()` is already idempotent (guarded by `cleaned`
flag), so this listener is safe alongside the existing 'close' and
'error' paths that also call it.

ALIGNMENT: cli.js has no equivalent subprocess-pool / concurrency-
limit logic — cli.js is a single-user CLI, the process being pooled,
not the pool itself. Per ALIGNMENT.md Rule 2, this fix is proxy-
internal (subprocess lifecycle management) with no cli.js equivalent
to cite; documented here instead. No wire-protocol, HTTP surface, or
response shape change (Rule 3 preserved).

Release kit: bumps version to 3.11.1 and adds CHANGELOG entry so the
auto-release workflow tags v3.11.1 on merge. README version refs are
feature-gate markers for v3.11.0 (models.json SPOT / auto-sync) and
remain historically accurate — no README change needed.

Fixes #37.
