## Summary
- **Fix CI build failure**: Auth0Client crashes during Next.js
prerendering when env vars aren't set. Returns a no-op stub (`getSession
→ null`) when domain is missing — semantically correct for static
generation
- **Lazy-load markdown libs (~260kb)**: ReactMarkdown, remarkGfm, and
react-syntax-highlighter were eagerly imported in monaco-diff-viewer but
only rendered when user expands "Generated Tests". Extracted into a
dynamic component
- **Parallelize repo detail query**: `getRepositoryById` ran the
activity count sequentially after the repo lookup. Since `repoId` is
already available, all three queries now run in parallel
## Test plan
- [ ] CI `build` check passes (was failing since #2598)
- [ ] Trace page still renders generated tests correctly when expanded
- [ ] Repository detail page loads correctly with activity status
## Summary
- Restructure CLAUDE.md hierarchy so Claude Code auto-discovers
project-specific instructions
- Delete dead `AGENTS.md` files (referenced non-existent
`.tessl/RULES.md`)
- Rename `django/aiservice/AGENTS.md` → `CLAUDE.md` for auto-discovery
- Create `js/CLAUDE.md` with package commands and gotchas
- Move PR review guidelines to `.claude/rules/pr-review.md` (auto-loaded
rule)
- Move prek workflow to `.claude/skills/fix-prek.md` (on-demand skill)
- Add path-scoped rules for Python and Next.js patterns
- Add domain glossary, service architecture diagram, and per-package
gotchas
## Test plan
- Verify `CLAUDE.md` files exist at root, `django/aiservice/`, and `js/`
- Verify no remaining references to `AGENTS.md` or `.tessl/`
- Verify `.claude/rules/` and `.claude/skills/` files are committed
