frontend: optimize Claude context files and add legacy import linter warnings#2227
Conversation
…nings Trim AGENTS.md, split oversized SKILL.md files into focused entrypoints with reference files, and delete/merge redundant rules. - AGENTS.md: 86 → 47 lines (remove discoverable patterns, add verify cmd) - e2e-tester SKILL.md: 725 → 80 lines (split into 3 reference files) - form-refactorer SKILL.md: 252 → 77 lines - Delete 15 rules (basic JS, linter-enforced, merged overlaps) - Fix factual errors (wrong utility names, Next.js assumptions) - Remove inert `globs` from skill rules (not supported there) - Add .claude/rules/test-unit-vs-integration.md (paths auto-loading) - Add noRestrictedImports warnings to biome.jsonc for legacy packages

Motivation
Two recent papers show that bloated context files hurt agent performance:
Key takeaway: every line in a context file should pass the test "would removing this cause Claude to make mistakes?" — if not, cut it. And never send an LLM to do a linter's job.
