add documentation for ai agents (#3115)

* add documentation for ai agents

* docs: consolidate CLAUDE.md and CONTRIBUTING.md, add style guidelines

- Refactor CLAUDE.md to reference CONTRIBUTING.md for build/test/format info
- Expand CONTRIBUTING.md with comprehensive build targets, env vars, and testing
- Add code style guidelines section with conventional commits
- Standardize SDK prettier config to use single quotes (matching web)
- Add project-level Claude Code settings to disable co-author attribution

* style(sdk): apply prettier with single quotes

Run prettier across sdk/base and sdk/package to apply the
standardized quote style (single quotes matching web).

* docs: add USER.md for per-developer TODO filtering

- Add agents/USER.md to .gitignore (contains user identifier)
- Document session startup flow in CLAUDE.md:
  - Create USER.md if missing, prompting for identifier
  - Filter TODOs by @username tags
  - Offer relevant TODOs on session start

* docs: add i18n documentation task to agent TODOs

* docs: document i18n ID patterns in core/

Add agents/i18n-patterns.md covering rust-i18n setup, translation file
format, t!() macro usage, key naming conventions, and locale selection.
Remove completed TODO item and add reference in CLAUDE.md.

* chore: clarify that all builds work on any OS with Docker
