v2: make v2 the main entry point, move v1 to src/v1/

- Move all v1 files (index, router, container-runner, db, ipc, types,
  logger, channels/registry, and all utilities) to src/v1/ as a
  fully self-contained archive with no shared dependencies
- Rename v2 files to remove -v2 suffix (index-v2.ts → index.ts, etc.)
- Update all imports across v2 source, tests, and setup files
- Migrate shared utilities (config, env, container-runtime, mount-security,
  timezone, group-folder) from pino logger to v2 log module
- Migrate setup/ files from logger to log with argument order swap
- Container agent-runner: move v1 entry to v1/, rename v2 to index.ts
- Update setup skill to offer all 13 v2 channels
- Install all Chat SDK adapter packages
- dist/index.js now runs v2; dist/v1/index.js runs v1
