chore: standardize config, MCP, agents, and docs

- Add .eslintcache to .gitignore
- Fix .mcp.json typo (http:/ → http://), add github server, use localhost:8086 for playwright
- Add "github" to .claude/settings.local.json enabled servers
- Create .claude/agents/ with 3 meta-orchestration agents (organizer, coordinator, installer)
- Remove unused lodash from tsconfig.json types
- Remove inaccurate "MCP Servers" section from CLAUDE.md
- Fix CLAUDE.md filename casing (claude.md → CLAUDE.md)
