enricobuehlerandClaude Opus 4.8 46c0e0e483 feat(host/hooks): operator hooks — exec + webhooks on lifecycle events (M2a) ...

hooks.json (RFC §6): commands and webhooks fired on host lifecycle events,
managed over GET|PUT /api/v1/hooks (validated, applied immediately) and
dispatched fire-and-forget by a bus-subscriber runner — hooks observe,
never veto, and no operator code sits in any streaming path.

- exec: detached sh -c with the event JSON on stdin + flat PF_EVENT_* env
  (the PF_STREAM_* vocabulary's sibling), per-hook timeout (default 30 s)
  with process-group kill, off-thread reap, per-hook debounce, bounded
  concurrency (8 in flight, excess dropped loudly). Windows runs hooks in
  the interactive user session (temp-file JSON argument; console-mode dev
  hosts get env + stdin like Unix).
- webhook: POST the event JSON, TLS-verified, redirects never followed, no
  punktfunk credentials outbound; optional per-hook secret file yields
  X-Punktfunk-Signature: sha256=<hex HMAC> (fails closed if unreadable).
- filters: exact-match client/fingerprint/plane/app + the same kind
  patterns as the SSE ?kinds= filter (shared crate::events::kind_matches).
- hardening (RFC §9.1): hooks.json via the private-dir/secret-file
  helpers; a hook script path must be operator/root-owned and not
  group/world-writable or it is refused loudly (the sshd rule).
- env mirrors PUNKTFUNK_ON_CONNECT_CMD / PUNKTFUNK_ON_DISCONNECT_CMD for
  the zero-config cases, beside PUNKTFUNK_RECOVER_SESSION_CMD.

Live-verified on Linux: PUT config via API → library.changed fired a real
script (env + stdin observed) and an HMAC webhook (receiver-verified
signature); a chmod-777 script was refused. 342 host tests green
(store/validation/filter/env-flatten/exec-timeout/ownership + routes),
clippy clean.
