chore: update dependencies and improve documentation

- implementation of Mileston 0
- Updated '@types/node' version from 22.15.0 to 22.15.2 across multiple packages in pnpm-lock.yaml.
- Enhanced architecture diagram in architecture.md for better clarity and visual representation.
- Added a new trade_log table in migrations/001_init.sql to track trade transactions.
- Minor formatting changes in README.md and public/dev-journey/M0.mdx for improved readability.
