fix: profile creation fallback when hermes_cli unavailable (Docker)

When hermes-agent is not discoverable (common in Docker), create_profile_api()
raised a hard RuntimeError while list and delete already had manual fallbacks.

Changes:
- Add _create_profile_fallback() that bootstraps profile directory structure
  directly (matching upstream hermes_cli.profiles: 8 subdirs + config clone)
- Extract _validate_profile_name() so validation works without hermes_cli
- Add constants _PROFILE_ID_RE, _PROFILE_DIRS, _CLONE_CONFIG_FILES matching
  upstream hermes-agent
- Remove :ro from docker-compose.yml hermes home mount so profiles dir is
  writable inside the container

Closes #44
