Fix: Security, reliability, and code quality improvements from PR review

Critical Security Fixes:
- Fix command injection vulnerability in Windows shims (beadboard.cmd, bb.cmd)
  - Added path validation to block traversal (.. and root-relative paths)
  - Added quotes around env var to prevent command injection

Reliability Fixes:
- Fix agent cache null safety bug
  - Fixed callBdAgentShow() to check for cache misses (null check, expiration)
  - Fixed getCachedAgent to properly return entry.data or null
- Fix null body crashes in mail ack route
  - Added null check before casting body to object
  - Returns 400 error instead of 500 for invalid requests

BD Compliance Fixes:
- Fix read-issues to use BD audit record path
  - Ensures all writes go through bd audit record
  - Maintains watcher/SSE parity and Dolt commit tracking

Code Quality Fixes:
- Fix path canonicalization violations
  - Use canonicalizeWindowsPath() and windowsPathKey() from pathing module
  - Prevents Windows edge cases and ensures machine-reproducible paths
- Fix typo: mobile-fronted → mobile-frontend
- Pin GitHub Actions tags
  - softprops/action-gh-release@v1 → specific commit hash
- Register pr14 test in package.json (already registered)

Testing:
- Refactor broad exception handlers in Python scripts
  - Replace except Exception: with specific exceptions
  - Allows KeyboardInterrupt and SystemExit to propagate correctly
  - All tests passing
