* feat(hub): drop mode/sdkLoader/SdkDispatchFailed (#175)
The Command Routing Hub no longer carries dual-runtime selection.
Removes `mode` and `sdkLoader` constructor parameters and the
`SdkDispatchFailed` and `SdkLoadFailed` errorKind values. The Hub
now routes exclusively through the CJS registry / handler resolution
path. ERROR_KINDS enum shrinks from 6 to 4 values.
phase-command-router.cjs updated to construct the Hub without the
removed params (removes tryLoadSdk, getExecuteForCjs, sdkLoader fn,
mode variable, and the post-dispatch SDK output branch). The 7
remaining family routers (init, phases, roadmap, state, validate,
verify, cjs-command-router-adapter) do not use createHub directly
and require no changes.
The CJS↔SDK bridge (bin/lib/cjs-sdk-bridge.cjs) is unchanged and
remains separately invokable; its removal is tracked in Phase 4 (#190).
ADR-0012 is no longer amended in this PR — the decision is captured
in ADR-0174 (which supersedes ADR-0012 entirely as part of the
SDK-retirement migration). Amending a superseded ADR would be
redundant noise.
Tests:
- Added assertions that Hub rejects/ignores `mode` and `sdkLoader`
- Removed obsolete mode-selection branching tests
- 57/57 local tests pass
Closes#175.
Part of #174 (ADR-0174).
* chore(changeset): add docs-exempt marker (#175)
P1.1's CommandRoutingHub work has no docs/ touchpoints — the
architectural decision is captured in ADR-0174 (merged via PR #198).
Per-phase ADR amendments would create noise; the SDK-retirement
migration's docs land in Phase 6 PRs (#193-#196) once the relevant
state is removed.
Adds the standard <!-- docs-exempt: <reason> --> marker inside the
changeset fragment so lint:docs accepts the PR without forcing a
docs/ touch that would be redundant.
