* feat(#3351): add trusted-header auth core
* fix(#3351): reconcile trusted sessions per request
* fix(#3351): preserve valid trusted group mappings
* fix(#3351): defer trusted logout reconciliation until after csrf
* fix(auth): clear _pending_set_cookies in reset_trusted_auth_request_state (keep-alive cookie cross-request leak)
Codex gate CORE finding: a Set-Cookie queued in request N but not flushed
survived onto the reused HTTP/1.1 handler and could be emitted by request N+1
— after trusted-identity rotation on logout this could overwrite a valid login
cookie and 401 the user. Reset the queue at the per-request boundary + add a
keep-alive regression test.
* docs(.env.example): document trusted-header auth / reverse-proxy SSO env vars
HERMES_WEBUI_TRUSTED_AUTH_HEADER + TRUSTED_PROXY_CIDRS (with exact-proxy-IP
security warning) + optional groups-header/JSON group-profile-map/logout-url.
* Release exp-v0.52.43: trusted-header auth / reverse-proxy SSO (#5568, #3351) + keep-alive cookie fix + docs

Greptile caught two example values that disagreed with the code defaults in
api/streaming.py: PREFILL_MESSAGES_SCRIPT_TIMEOUT is 5s (not 10) and
PREFILL_CONTEXT_MAX_CHARS is 12000 (not 20000). An operator uncommenting
either line verbatim would have silently diverged from the real default.
