Verifies the board mutation guard blocks requests when
X-Forwarded-Host is present but Origin does not match it.

Behind a reverse proxy with a custom port (e.g. Caddy on :3443), the
browser sends an Origin header that includes the port, but the board
mutation guard only read the Host header which often omits the port.
This caused a 403 "Board mutation requires trusted browser origin"
for self-hosted deployments behind reverse proxies.
Read x-forwarded-host (first value, comma-split) with the same pattern
already used in private-hostname-guard.ts and routes/access.ts.
Fixes#1734
Update dev origin allowlist and tests to use port 3100 only, matching
the unified dev server setup. Fix AGENTS.md and README accordingly.

Wire up Better Auth for session-based authentication. Add actor middleware
that resolves local_trusted mode to an implicit board actor and authenticated
mode to Better Auth sessions. Add access service with membership, permission,
invite, and join-request management. Register access routes for member/invite/
join-request CRUD. Update health endpoint to report deployment mode and
bootstrap status. Enforce tasks:assign and agents:create permissions in issue
and agent routes. Add deployment mode validation at startup with guardrails
(loopback-only for local_trusted, auth config required for authenticated).

Require trusted browser origin (Origin or Referer header) for
mutating requests from board actors, preventing cross-origin
mutation attempts against the local-trusted API.
