feat(aliases): implement first-letter shorthand aliases for all bin scripts with collision handling

- Added alias functions to all bin scripts using first-letter pattern (e.g., `av` for `activate-venv`, `cwl` for `commit-with-llm`)
- Implemented collision resolution by extending aliases with additional letters when conflicts occur or when shadowing standard shell commands
- Documented alias implementation approach in library.md with complete alias map for reference
- Verified shell syntax with `bash -n` and ensured proper argument passing with `"$@"`
- Updated prompt frontmatter to reflect completed state and model used (infomaniak/moonshotai/Kimi-K2.6)
