feat: ship deterministic architecture CLI MVP

[rajanbor]

Outcome

Ships the deterministic, offline architecture workflow described in the MAP MVP.

CLI

• add compatible list, search, show, scan, and suggest workflow names
• retain patterns, explain, analyze, and recommend
• add versioned JSON scan and recommendation output
• derive detected, likely, and unknown certainty from preserved numeric confidence
• report inspected manifests, analyzers, evidence, and explicit limitations
• implement map graph over all 96 catalog nodes and normalized typed edges
• implement map validate for project manifests and adopted-pattern integrity

Contracts

• add Scan Result v1 and Recommendation Result v1 JSON Schemas
• add complete valid examples and three invalid fixtures per contract
• validate six public contracts in CI

Dogfood

The built CLI successfully scanned and suggested against tooling, inspected the graph for retrieval/chunking, and validated this repository’s .map workspace. The scan correctly reports its root-manifest and monorepo limitations instead of treating missing evidence as absence.

Verification

• registry: 96 patterns
• schemas: 6 contracts
• build, lint, typecheck: pass
• tests: 146 pass (130 CLI, 13 score, 3 registry)
• built CLI JSON smoke tests: scan, suggest, graph, validate pass
