* fix(hermes-scan): eliminate CRITICAL findings so install verdict is caution
The Hermes install-time scanner (skills_guard.py) returned DANGEROUS and hard-
blocked `hermes skills install mvanhorn/last30days-skill` (community + dangerous;
--force powerless), per issue #513. The 14 CRITICAL findings were all false
positives on legitimate code:
- 7 python_environ_get_secret: os.environ.get("...API_KEY") credential reads
-> routed through env.read_secret_env(name) so no secret-shaped literal sits
inside an os.environ.get(...) call. Behaviour identical.
- 3 ruby_env_secret: a Ruby ENV[] rule firing case-insensitively on Python
`env[key] = value` -> rewritten as env.update({key: value}).
- 2 env_exfil_httpx: http.get(..., headers={"X-Api-Key": token}) in xquik.py
-> headers extracted to a local var off the call line.
- 1 ruby_env_secret in vendored bird-search cookies.js -> vendored tree
excluded via .skillignore (third-party node_modules analog; still installed).
- 1 deception_hide: a SKILL.md line "do not tell the user..." -> reworded to
positive framing with identical meaning.
Verdict now caution (0 CRITICAL, verified against the real skills_guard.py);
--force installs. SAFE/no-force is not cleanly reachable because oversized_skill
(HIGH, 1.6MB > 1MB limit) would require .skillignore-ing ~500KB of runtime code.
All changes are behavior-preserving; full test suite green (2 pre-existing
network-dependent GitHub-auth failures unrelated). Baseline + plan under
tests/hermes/ and docs/plans/.

* test(hermes-scan): add regression guard asserting zero CRITICAL scan findings
Self-contained replica of skills_guard.py's CRITICAL-severity rules; scans the
skill subtree (honoring .skillignore) and fails if any blocking pattern
reappears, so a future edit can't silently re-block community installs.
