Added SessionStart hook that adds $CLAUDE_PROJECT_DIR/target/release
to PATH via CLAUDE_ENV_FILE. This makes `blue` available by name in
all subsequent hooks.
- .claude/hooks/session-start.sh: Sets PATH on session start
- .claude/hooks/guard-write.sh: Now uses `blue` instead of full path
- .claude/settings.json: Added SessionStart hook
Requires Claude Code restart to take effect.
