* feat(gateway): support hot reload and empty startup
- extract gateway runtime into pkg/gateway
- add gateway.hot_reload config with default and example values
- allow starting the gateway without a default model via --allow-empty
- stop treating missing enabled channels as a startup error
- update related tests
* feat: replace gateway SSE updates with polling-based state sync
- remove gateway SSE broadcasting and event endpoint
- add polling-based gateway status refresh with stopping state handling
- detect when gateway restart is required after default model changes
- resolve gateway health and websocket proxy targets from configured host
- update gateway UI labels and add backend/frontend test coverage
* refactor(cli): migrate to Cobra-based command structure
Refactor CLI to use Cobra instead of manual os.Args parsing.
- Introduce root command and structured subcommands under cmd/picoclaw/internal
- Convert agent, auth, cron, gateway, migrate, onboard, skills, status and version to Cobra commands
- Replace manual flag parsing with Cobra flags
- Remove direct os.Args usage from command handlers
- Keep existing command behavior and output semantics
This change focuses on CLI structure and maintainability.
No business logic changes intended.
* chore(cli): remove version2 alias and make cobra a direct dependency
* test(cli): add basic command tests
- Add tests for CLI command tree and flag parsing
- Align LDFLAGS injection path for version info
- Remove unused manual help function
* test: migrate command tests to testify assertions
Replace standard library testing error checks (t.Error*, t.Fatalf)
with assert/require from stretchr/testify across all cobra command tests
for improved readability and consistency.
* fix(cli): make linter happy
* test: avoid duplication in windows config path test
* test: simplify allowed command checks using slices.Contains
* fix(skills): register subcommands during command construction
- Move subcommand registration out of PersistentPreRunE
- Ensure `picoclaw skills <subcommand>` resolves correctly
- Minor install command and test cleanups
* refactor(cli): address review feedback and improve command clarity
* fix(authLogoutCmd): rm os.Exit
