Fail closed when the Agent Git identity disappears or is unreadable, including when the revision read itself raises — a missing revision is indistinguishable from changed source and must never be treated as proof the loaded code is current.

* rebase #7160 onto master (report unverified Agent updates, no auto-restart)

* harden agent-update marker read: no-follow, fstat regular-file, bounded (fixes gate CORE)
The Agent update marker is attacker-adjacent shared state. _read_live_agent_update()
used Path.read_text(), which follows symlinks, blocks forever on a FIFO, and reads an
unbounded regular file — a rejected/stale-runtime request could hang or OOM. Now opens
O_RDONLY|O_NONBLOCK|O_NOFOLLOW, fstat-verifies a small regular file, and reads a bounded
max, classifying anything else as 'unknown' (fail-closed). Adds FIFO/oversized/symlink/
happy-path regression tests.

* fix marker-read portability: gate os.open fast-path on O_NONBLOCK+O_NOFOLLOW
os.O_NONBLOCK is Unix-only; accessing it unconditionally raised AttributeError
on native Windows, breaking every stale-revision barrier (chat/compression/etc).
Now both flags resolve via getattr and the os.open() fast path is taken only
when BOTH are available (_MARKER_SAFE_OPEN_AVAILABLE); otherwise fall back to an
lstat-only classification (absent vs unknown) so a fallback platform can never
symlink-traverse or crash. Adds a Windows-fallback regression test.

* fix: suppress console windows for git subprocess calls on Windows
On Windows, every git.exe spawned by the WebUI (update checks,
version detection, workspace git info, rollback inspection,
worktree management) creates a visible console window. When
Windows Terminal is the default terminal, each short-lived git
process opens a new tab. Combined with the 60-second version-skew
monitor polling /api/settings and the boot-time update check, this
produces a flood of flashing terminal tabs.
Root cause: subprocess.run() calls in api/updates.py, api/rollback.py,
api/worktrees.py, and api/workspace.py did not pass
creationflags=CREATE_NO_WINDOW on Windows. api/workspace_git.py
already had the fix (#5692); these four files were missed.
Backend fix:
- Add _windows_hide_flags() helper to each affected module
(mirrors the existing pattern in api/workspace_git.py)
- Pass creationflags=_windows_hide_flags() to all git
subprocess.run() calls (10 call sites across 4 files)
Frontend fix (prevent timeout->retry cascades):
- Increase update-check timeout from 30s/60s to 300s (5 min)
- Increase /api/settings fetches from 30s to 60s
- Increase /api/git-info fetch from 30s to 60s
The backend git fetch to GitHub can take 15s per repo; with both
WebUI and Agent repos checked sequentially plus other git calls,
the total easily exceeds the old 30s default frontend timeout,
triggering the api() wrapper auto-retry (3 attempts) and
amplifying the git process flood.
* [verified] fix: address Windows git subprocess review
