Affaan Mustafa 90ea2f327c fix: 2 bugs fixed, 17 tests added for hook scripts
Bug fixes:
- evaluate-session.js: whitespace-tolerant regex for counting user
  messages in JSONL transcripts (/"type":"user"/ → /"type"\s*:\s*"user"/)
- session-end.js: guard against null elements in content arrays
  (c.text → (c && c.text) to prevent TypeError)

New tests (17):
- evaluate-session: whitespace JSON regression test
- session-end: null content array elements regression test
- post-edit-console-warn: 5 tests (warn, skip non-JS, clean files,
  missing file, stdout passthrough)
- post-edit-format: 3 tests (empty stdin, non-JS skip, invalid JSON)
- post-edit-typecheck: 4 tests (empty stdin, non-TS skip, missing file,
  no tsconfig)

Total test count: 191 (up from 164)

/**
* Continuous Learning - Session Evaluator
*
* Cross-platform (Windows, macOS, Linux)
*
* Runs on Stop hook to extract reusable patterns from Claude Code sessions.
* Reads transcript_path from stdin JSON (Claude Code hook input).
*
* Why Stop hook instead of UserPromptSubmit:
* - Stop runs once at session end (lightweight)
* - UserPromptSubmit runs every message (heavy, adds latency)
