Tom Boucher b533f71857 chore: introduce CommandRoutingHub and migrate phase-command-router (PoC) (#3828)
* feat(routing): add CommandRoutingHub with behavioral test suite (#3788)

Introduces createHub({ mode, sdkLoader, cjsRegistry, manifest }) and
hub.dispatch({ family, subcommand, args, cwd, raw }) -> Result with a
closed 6-value ERROR_KINDS frozen enum. Hub never throws, never prints,
and enforces no transparent fallback between sdk/cjs modes. 34 behavioral
tests cover all errorKind values, mode fixation, and the no-throw contract.

* refactor(routing): migrate phase-command-router to CommandRoutingHub (#3788)

Rewrites phase-command-router.cjs to dispatch through CommandRoutingHub.
Public entry point routePhaseCommand({ phase, args, cwd, raw, error }) is
unchanged. The adapter determines mode (sdk/cjs) from env + tryLoadSdk(),
constructs a hub, dispatches, and translates the pure Result back to
output()/error() calls. New behavioral test suite (23 tests) replaces the
old mock-heavy approach and includes two integration tests through the real hub.

* docs(routing): ADR + glossary + changeset for CommandRoutingHub (#3788)

Adds ADR-3788 documenting the hub's design contract (pure result, fixed mode,
closed 6-value errorKind enum, no transparent fallback). Adds Command Routing
Hub glossary entry to CONTEXT.md and a one-paragraph reference to
ARCHITECTURE.md. Changeset fragment records the Changed entry.

* fix(docs): rename ADR to sequential convention 0012 (#3788)

* docs(inventory): register CommandRoutingHub in INVENTORY (#3788)

Add command-routing-hub.cjs row to docs/INVENTORY.md CLI Modules table,
bump headline count from 72 to 73, and regenerate INVENTORY-MANIFEST.json
via scripts/gen-inventory-manifest.cjs --write.

* docs(adr): add 0012 to ADR index (#3788)

Add entry for 0012-command-routing-hub.md to the index table in
docs/adr/README.md so the enh-3271-sdk-adr-structure lint passes.

* chore(lint): bump phase test-file ceiling to accommodate command-router suite (#3788)

phase-command-router.test.cjs added by the CommandRoutingHub migration
pushes the phase prefix cluster from 4 to 5 test files. Bump the allowlist
ceiling from 4 to 5 (issue 3788) so lint-test-file-count passes.

* fix(routing): preserve phase.mvp-mode JSON error and ROADMAP scan through hub (#3788)

mvp-mode was never registered in the SDK; the pre-#3788 CJS router
always dispatched it via the CJS handler even when sdkAvailable was
true. After the hub migration, SDK-mode hubs (Docker, where the SDK
build exists) sent mvp-mode to the SDK bridge, which returned
SdkDispatchFailed with reason 'unknown' instead of the expected
'usage' code, and failed ROADMAP lookups. Fix by short-circuiting
mvp-mode to the CJS handler before hub construction, matching the
pre-migration observable behaviour.

* docs(adr): note SDK-incomplete subcommand limitation in ADR-0012 (#3788)

* fix(inventory): bump CLI Modules headline to 74 after rebase onto main (#3788)

Upstream added code-review-flags.cjs (72→73) at the same time our branch
added command-routing-hub.cjs. After rebase both modules exist (74 total)
but the headline stayed at 73; bump to 74.

* fix(routing): remove dead mvp-mode handler from cjsRegistry (#3788)

The cjsRegistry['phase']['mvp-mode'] handler (previously lines 65–68)
was unreachable: the early-return bypass at line 56 intercepts mvp-mode
before hub construction in CJS mode, and in SDK mode cjsRegistry is
passed as undefined. Remove the dead handler; all 57 tests still pass.

* docs(adr): correct router count in ADR-0012 (#3788)

The context section cited "eight" routers including "frontmatter" but
there is no frontmatter-command-router.cjs. The actual count is seven:
phase, phases, roadmap, state, verify, validate, init.

* fix(routing): guard missing subcommand + use ERROR_KINDS constant (#3788)

Two fixes in phase-command-router.cjs:

1. Add early-return for missing subcommand before hub construction.
   Pre-#3788 the routeCjsCommandFamily fell through to error() for
   undefined args[1]; post-#3788 the hub's manifest check skips falsy
   subcommands, which would have sent bare 'phase' into SDK dispatch
   in SDK mode instead of the expected "Available: ..." error message.

2. Switch on ERROR_KINDS.UnknownCommand instead of bare 'UnknownCommand'
   string, per ADR-0012's closed-enum contract ("callers switch on
   ERROR_KINDS values, not bare string literals").

* docs(routing): fix factual errors in ARCHITECTURE, ADR-0012, changeset (#3788)

Three corrections:

1. ARCHITECTURE.md: softened "All CJS command family routers dispatch
   through CommandRoutingHub" — only phase-command-router.cjs is
   migrated in this PR; remaining routers still use routeCjsCommandFamily
   and migrate in follow-up issues.

2. ADR-0012: corrected the SDK mvp-mode claim. The ADR said "the SDK
   has no equivalent entry" but sdk/src/query/command-static-catalog-
   domain.ts:104-105 registers phase.mvp-mode. The actual reason for
   the early-return bypass is divergent ROADMAP scan behaviour and
   error reason codes, not SDK absence.

3. .changeset/mellow-tigers-gather.md: corrected pr: 1 → pr: 3828.
