feat: add copilot-persistence feature (#10)

* feat: add copilot-persistence feature

Persists GitHub Copilot CLI settings and chat history across container
rebuilds using a named Docker volume mounted at /copilot-data with a
symlink from ~/.copilot.

- Add install script with root/non-root user handling
- Add devcontainer-feature.json with volume mount and env var
- Add tests (default, debian, ubuntu scenarios)
- Update root README with feature documentation
- Disable generate-docs to preserve custom feature READMEs

* ci: add copilot-persistence to test matrix

* refactor: address PR review feedback

- Resolve home directory via getent/passwd instead of hardcoding /home/<user>
- Use chmod 700 instead of 755 for sensitive copilot data
- Fix symlink guard to also verify target path points to /copilot-data
- Add documentationURL to devcontainer-feature.json
- Include copilot-cli feature in README usage example

Skipped configurable volume name - cross-project sharing is the intended
behavior for copilot data persistence.

* feat: scope volume per dev container using ${devcontainerId}

Matches the shell-history pattern from stuartleeks/dev-container-features.
Each dev container gets its own isolated copilot data volume.
