chore: migrate IDE environment from Kiro to Claude Code

- Add CLAUDE.md (root + ETL subdirectory + db subdirectory) consolidating all Kiro steering docs
- Add .mcp.json migrated from .kiro/settings/mcp.json (test DBs enabled, prod disabled)
- Add .claude/commands/ (audit, doc-sync, db-docs) replacing Kiro skills
- Add .claude/hooks/ (session_start, post_edit_audit, stop_audit_check) replacing Kiro hooks
- Add .claude/settings.json registering all hooks
- Add scripts/audit/prescan.py merging Kiro's audit_flagger + compliance_prescan
- Remove .kiro/agents, hooks, scripts, settings, skills, state (migrated or obsolete)
- Update .gitignore for Claude Code
