51f233582d Align call-protocol.md and api-surface.md with envelope model
Remove supersession note from response-envelopes.md — both dependent
docs now reflect the ResponseEnvelope system. Key changes:

- call-protocol.md: CallHandler wraps and publishes (not handlers),
  call.responded.output uses ResponseEnvelopeSchema, respond() enforces
  envelope guard, call() resolves ResponseEnvelope, subscribe() yields
  ResponseEnvelope, references shared result pipeline
- api-surface.md: execute() returns Promise<ResponseEnvelope<TOutput>>,
  OperationEnv functions return Promise<ResponseEnvelope>, CallHandler
  calls handler directly and applies shared pipeline, respond() requires
  ResponseEnvelope, added Response Envelope Types and Utilities sections
- response-envelopes.md: removed supersession note, added Shared Result
  Pipeline section (detect→wrap→normalize→validate), unified execute()
  and CallHandler integration points to reference shared pipeline,
  updated migration checklist to mark doc changes complete

81f89e0f6c Restructure response envelopes architecture: split ADR from spec, add Value.Cast composability, document implementation gaps
- Split monolithic 680-line response-envelopes.md into focused ADR-005
  (decisions/005-response-envelopes.md, 152 lines) and specification
  (response-envelopes.md, 441 lines)
- ADR-005: consolidate 10 inline ADRs into coherent decision record with
  rationale for data+meta envelope shape, handler responsibility shift,
  string discriminant detection, and composability analysis
- Spec: types, factory functions, integration points, constraints, migration
  checklist, and open questions
- Add MCP outputSchema extraction (2025-06-18+ spec) with FromSchema
  conversion and<Value.Cast()> normalization for structuredContent
- Add current-source-vs-spec implementation gap tables to registry, call,
  mcp adapter, and openapi adapter integration points
- Update adapters.md: from_mcp outputSchema extraction, structuredContent
  handling, isError non-throw behavior, Value.Cast() for data normalization
- Add open questions: serving directionality, JSON.stringify in MCP content,
  outputSchema extraction completeness, respond() visibility
- Note: existing call-protocol.md and api-surface.md describe pre-envelope
  behavior; this spec supersedes them until updated per migration checklist

a7e6cc94c7 Add response envelopes architecture spec (ADR-005 through ADR-014)
Introduce ResponseEnvelope as a first-class concept for uniform operation
result handling across MCP, OpenAPI, and local adapters. Key decisions:

- ResponseEnvelope<T> wraps every result with typed metadata
  (LocalResponseMeta, HTTPResponseMeta, MCPResponseMeta)
- CallHandler becomes sole publisher of call.responded (handler
  responsibility shift from publish-to-return)
- Envelope detection via closed-set string discriminant
  (isResponseEnvelope) — no Symbols, JSON-serializable
- MCP isError:true no longer throws; wraps in envelope with
  meta.isError flag preserving error content for consumers
- outputSchema validates envelope.data, not the full envelope
- PendingRequestMap.respond() validates envelope at runtime
- Factory functions (localEnvelope, httpEnvelope, mcpEnvelope)
  ensure consistent construction
- Breaking change: execute() returns ResponseEnvelope<TOutput>,
  call.responded.output is ResponseEnvelopeSchema
- No Client abstraction yet (ADR-014)
