Consolidate hooks: merge bin/hooks and hooks into single hooks/ directory

- Removed bin/hooks/ wrapper layer
- Moved all hook logic into consolidated hooks/*-hook.ts files
- Each hook now handles its own stdin/stdout/JSON wrapping
- Removed ALL try-catch blocks from context-hook (let errors surface)
- Updated build script to reference new src/hooks/ paths
- Reduced from 12+ files to 6 hook files

This simplifies the architecture and makes debugging actually possible.
