## Summary
- Extracted topic-specific learnings and guidelines from AGENTS.md into
9 separate files under `rules/` for better discoverability and
maintainability
- AGENTS.md now has a concise rules index table with "read when..."
descriptions so agents know which file to consult
- No content was lost — all learnings are preserved in their respective
rule files

## Test plan
- [x] Verify all rule files exist and contain the expected content
- [x] Verify AGENTS.md rules index links are correct
- [x] Lint, type checks, and tests all pass

## Summary by cubic
Modularized guidance from AGENTS.md into nine focused docs under rules/,
and added a concise rules index in AGENTS.md for quick navigation. No
content was removed; it’s now easier to find and maintain.

- **Refactors**
- Extracted topic docs into rules/: electron-ipc, e2e-testing,
git-workflow, base-ui-components, database-drizzle,
typescript-strict-mode, openai-reasoning-models, adding-settings,
chat-message-indicators.
- Updated .claude/commands/remember-learnings.md to write learnings to
rules/ (use AGENTS.md only when needed) and maintain the index when new
files are added.

<sup>Written for commit 7d217b84ce3d1e434f28a31bb6a2329c672d2bcf.
Summary will update on new commits.</sup>
