* fix(hooks): scrub secrets and harden hook security
- Scrub common secret patterns (api_key, token, password, etc.) from
observation logs before persisting to JSONL (observe.sh)
- Auto-purge observation files older than 30 days (observe.sh)
- Strip embedded credentials from git remote URLs before saving to
projects.json (detect-project.sh)
- Add command prefix allowlist to runCommand — only git, node, npx,
which, where are permitted (utils.js)
- Sanitize CLAUDE_SESSION_ID in temp file paths to prevent path
traversal (suggest-compact.js)

* fix(hooks): address review feedback from CodeRabbit and Cubic
- Reject shell command-chaining operators (;|&`) in runCommand, strip
quoted sections before checking to avoid false positives (utils.js)
- Remove command string from blocked error message to avoid leaking
secrets (utils.js)
- Fix Python regex quoting: switch outer shell string from double to
single quotes so regex compiles correctly (observe.sh)
- Add optional auth scheme match (Bearer, Basic) to secret scrubber
regex (observe.sh)
- Scope auto-purge to current project dir and match only archived
files (observations-*.jsonl), not live queue (observe.sh)
- Add second fallback after session ID sanitization to prevent empty
string (suggest-compact.js)
- Preserve backward compatibility when credential stripping changes
project hash — detect and migrate legacy directories
(detect-project.sh)

* fix(hooks): block $() substitution, fix Bearer redaction, add security tests
- Add $ and \n to blocked shell metacharacters in runCommand to prevent
command substitution via $(cmd) and newline injection (utils.js)
- Make auth scheme group capturing so Bearer/Basic is preserved in
redacted output instead of being silently dropped (observe.sh)
- Add 10 unit tests covering runCommand allowlist blocking (rm, curl,
bash prefixes) and metacharacter rejection (;|&`$ chaining), plus
error message leak prevention (utils.test.js)

* fix(hooks): scrub parse-error fallback, strengthen security tests
Address remaining reviewer feedback from CodeRabbit and Cubic:
- Scrub secrets in observe.sh parse-error fallback path (was writing
raw unsanitized input to observations file)
- Remove redundant re.IGNORECASE flag ((?i) inline flag already set)
- Add inline comment documenting quote-stripping limitation trade-off
- Fix misleading test name for error-output test
- Add 5 new security tests: single-quote passthrough, mixed
quoted+unquoted metacharacters, prefix boundary (no trailing space),
npx acceptance, and newline injection
- Improve existing quoted-metacharacter test to actually exercise
quote-stripping logic

* fix(security): block $() and backtick inside quotes in runCommand
Shell evaluates $() and backticks inside double quotes, so checking
only the unquoted portion was insufficient. Now $ and ` are rejected
anywhere in the command string, while ; | & remain quote-aware.
Addresses CodeRabbit and Cubic review feedback on PR #348.
