Affaan Mustafa f3a4b33d41 fix: harden CI validators, shell scripts, and expand test suite
- Add try-catch around readFileSync in validate-agents, validate-commands,
  validate-skills to handle TOCTOU races and file read errors
- Add validate-hooks.js and all test suites to package.json test script
  (was only running 4/5 validators and 0/4 test files)
- Fix shell variable injection in observe.sh: use os.environ instead of
  interpolating $timestamp/$OBSERVATIONS_FILE into Python string literals
- Fix $? always being 0 in start-observer.sh: capture exit code before
  conditional since `if !` inverts the status
- Add OLD_VERSION validation in release.sh and use pipe delimiter in sed
  to avoid issues with slash-containing values
- Add jq dependency check in evaluate-session.sh before parsing config
- Sync .cursor/ copies of all modified shell scripts

# Continuous Learning - Session Evaluator
# Runs on Stop hook to extract reusable patterns from Claude Code sessions
#
# Why Stop hook instead of UserPromptSubmit:
# - Stop runs once at session end (lightweight)
# - UserPromptSubmit runs every message (heavy, adds latency)
#
# Hook config (in ~/.claude/settings.json):
# {
# "hooks": {
# "Stop": [{
# "matcher": "*",
# "hooks": [{
# "type": "command",
# "command": "~/.claude/skills/continuous-learning/evaluate-session.sh"
# }]
# }]
# }
# }
#
# Patterns to detect: error_resolution, debugging_techniques, workarounds, project_specific
# Patterns to ignore: simple_typos, one_time_fixes, external_api_issues
# Extracted skills saved to: ~/.claude/skills/learned/
