Setup LLM Optimization

What This Sets Up

• SessionStart hook setting AI_AGENT=1, CLAUDECODE=1, and NODE_OPTIONS=--max-old-space-size=8192
• UserPromptSubmit hook injecting project state (git branch, dirty files, last commit, available scripts, session violations, active config) into every prompt as additionalContext — Claude starts each response knowing the project state without wasting tool calls
• PreToolUse hook optimizing test commands:
  • Strip --verbose (hard enforcement via updatedInput rewrite — wastes tokens)
  • Suggest --pool=forks (prevents zombie processes)
  • Suggest --bail=1 (fail fast, save tokens)
  • Suggest --teardownTimeout=5000 (prevent hanging teardown)
  • Suggest --reporter=github in CI
  • Jest: suggest --bail --forceExit
• PostToolUse hook truncating verbose bash output to reduce context bloat
