Codex SILENT finding: the new 'if not target.exists(): return {}' guard ran
BEFORE the ambient-resolver short-circuit, so a matching ambient profile home
whose directory does not physically exist (fresh install / monkeypatched cfg)
returned {} instead of deferring to get_config() — breaking in-memory overrides
and changing the default-profile missing-home path. Move the guard below the
ambient short-circuit; add a regression test (matching-but-nonexistent ambient
home still defers to get_config()).
The /api/profiles handler re-imported _is_isolated_profile_mode locally inside
handle_get, which made the name function-local for the ENTIRE handle_get scope
-> the earlier use at the /api/projects branch (routes.py:8000) hit
UnboundLocalError (F823), failing 6 test shards + lint. It's already a
module-level re-export (routes.py:429), so the local re-import is redundant;
removing it lets every in-function use resolve to the module global. Also drop
an unused 'from pathlib import Path' in the new #4449 state-dir test.

Gate-found (Codex CORE, repro'd): a hardlink at a clean *.md page name can
carry an arbitrary inode (incl. one outside the wiki) through the O_NOFOLLOW +
inode-identity read check — O_NOFOLLOW does not block hardlinks. Reject any
page file with st_nlink > 1 in BOTH the allowlist walk and the read-path
revalidation. Pre-existing on master (the inode recapture predates this PR's
cache); closing it here while on the read path. +1 toothed regression test
(prime cache -> hardlink listed page to outside secret -> assert 404, no leak).

Gate-found: reaping on started_at age alone could pop a genuinely-live worker
that's mid-teardown past the 180s ceiling (active_stream_id cleared during final
writeback, STREAMS entry still present) — ACTIVE_RUNS is worker-lifecycle truth
for health/background-wakeup/agent-cache consumers. Add a 'not in STREAMS'
guard (snapshot taken sequentially before ACTIVE_RUNS_LOCK, no nesting) and pop
by the real dict key. +1 regression test (toothed). Keeps the anti-permanent-409
age behavior intact.
