paseo-bot[bot]andluke 798b546e73 fix(omp): release closed sessions retained by mount notices
Keep per-session notice identity without keeping the session and its runtime reachable from the client-wide ledger.

paseo-bot[bot] 16f688b726 test(server): stop pending setup before removing its fixture (#8624)
* test(server): diagnose recurring Windows setup timeout

* test(server): stop pending setup before removing its fixture

A test deadline does not cancel background setup. Abort and join it before deleting its working directory, and cover teardown with a deliberately live setup child. Keep the existing subdirectory shell assertions and timeout.

* test(server): preserve setup readiness filesystem errors

paseo-bot[bot]andHomicideZero b507fc1986 fix(server): return 404 for missing well-known metadata (#8622)
* fix(server): return 404 for unserved well-known paths

The daemon web UI middleware fell back to the SPA's index.html for every
unknown GET, including /.well-known/* URIs. MCP clients that run OAuth
discovery (RFC 9728 protected resource metadata, RFC 8414 authorization
server metadata) received a 200 text/html body, treated it as malformed
metadata and retried instead of concluding the server has no OAuth.

Well-known paths now serve a real file from the dist directory if one
exists and otherwise return a JSON 404. Other paths keep the SPA fallback.

* fix(server): verify metadata routing through the daemon

Retain the contributed well-known routing fix with named resolver options and a full daemon regression that fails when metadata requests receive app HTML.
