Affaan Mustafa 36864ea11a fix: harden error handling, fix TOCTOU races, and improve test accuracy
Core library fixes:
- session-manager.js: wrap all statSync calls in try-catch to prevent
  TOCTOU crashes when files are deleted between readdir and stat
- session-manager.js: use birthtime||ctime fallback for Linux compat
- session-manager.js: remove redundant existsSync before readFile
- utils.js: fix findFiles TOCTOU race on statSync inside readdir loop

Hook improvements:
- Add 1MB stdin buffer limits to all PostToolUse hooks to prevent
  unbounded memory growth from large payloads
- suggest-compact.js: use fd-based atomic read+write for counter file
  to reduce race window between concurrent invocations
- session-end.js: log when transcript file is missing, check
  replaceInFile return value for failed timestamp updates
- start-observer.sh: log claude CLI failures instead of silently
  swallowing them, check observations file exists before analysis

Test fixes:
- Fix blocking hook tests to send matching input (dev server command)
  and expect correct exit code 2 instead of 1
