fix(mcp): apply_patch preserves schema-defaulted ids in multi-op batches

SceneBridge.applyPatch now threads the Zod-parsed node through to the
apply phase instead of the raw input. Previously, when a caller sent a
create patch without an `id` field, the schema's objectId default ran
during dry-run parsing but only in `res.data`; the apply phase pushed
the unparsed `p.node` (no id) to the store, so subsequent tools that
walked `level.children` crashed on undefined entries (e.g.
duplicate_level -> cloneLevelSubtree -> extractIdPrefix(undefined)).

Also adds test-reports/ artefacts from live end-to-end testing:
- t1-stdio: 21/21 tools pass via stdio (~106ms)
- t2-http: connect/single-session behaviour (HTTP transport quirk
  documented)
- t3-scenario: 2-bedroom apartment built end-to-end — 12/12 steps
  after this fix (24 final nodes, validate=true, apartment.json
  exported)
- t4-errors: 24/24 invalid-input cases rejected with proper MCP errors
- t5-resources-prompts: 4/4 resources, 3/3 prompts, dev server
  /api/health 200 OK

Transport: Streamable HTTP (single-session stateful)
## Summary
- Tools exercised: 21
- Passes: 0/21
- Expected tool count (21) on first listTools: (got 0)
- Session state stable across two listTools() calls: n/a
- Session A connected: false — error: Streamable HTTP error: Error POSTing to endpoint: {"jsonrpc":"2.0","error":{"code":-32600,"message":"Invalid Request: Server already initialized"},"id":null}
- Session B connected: no
- Two clients got distinct session IDs: n/a
- Session B listTools count: n/a
- Shared SceneBridge observation: n/a (could not connect)
## Latency (get_scene × 0 on session A)
| Metric | ms |
|--------|----|
| p50 | 0.0 |

## Server state probes
Before the SDK-based test run, these HTTP probes were executed:
- POST initialize (no session) → 200: `event: message
data: {"result":{"protocolVersion":"2025-03-26","capabilities":{"tools":{"listChanged":true},"resources":{"listChanged":true},"prompts":{"listChanged":true}},"serverInfo":{"name":"pasca`
- POST tools/list (no session) → 400: `{"jsonrpc":"2.0","error":{"code":-32000,"message":"Bad Request: Mcp-Session-Id header is required"},"id":null}`
- GET /mcp (no session) → 400: `{"jsonrpc":"2.0","error":{"code":-32000,"message":"Bad Request: Mcp-Session-Id header is required"},"id":null}`
- DELETE /mcp (no session) → 400: `{"jsonrpc":"2.0","error":{"code":-32000,"message":"Bad Request: Mcp-Session-Id header is required"},"id":null}`
## HTTP-specific quirks
- `packages/mcp/src/transports/http.ts` uses a single
`StreamableHTTPServerTransport` per process with stateful session-id
generation. The SDK's transport sets `_initialized=true` on the first
valid `initialize` POST and never clears it. Consequence: the running
server can only ever accept **one** session for its lifetime; subsequent
`initialize` requests receive HTTP 400 `{"code":-32600,"message":"Invalid Request: Server already initialized"}`.
- Because both sessions (when connect succeeds) share the same
`SceneBridge` singleton, any mutation made on one session is visible to
the other. This is expected given the server holds one bridge process-wide.
- `not_implemented`, `catalog_unavailable`, and `sampling_unavailable`
responses are treated as passes per the agreed test protocol.
## Notes
- Server was in a clean state and accepted both sessions.

## Server state probes
Before the SDK-based test run, these HTTP probes were executed:
${probeBlock}
## HTTP-specific quirks
- \`packages/mcp/src/transports/http.ts\` uses a single
\`StreamableHTTPServerTransport\` per process with stateful session-id
generation. The SDK's transport sets \`_initialized=true\` on the first
valid \`initialize\` POST and never clears it. Consequence: the running
server can only ever accept **one** session for its lifetime; subsequent
\`initialize\` requests receive HTTP 400 \`{"code":-32600,"message":"Invalid Request: Server already initialized"}\`.
- Because both sessions (when connect succeeds) share the same
\`SceneBridge\` singleton, any mutation made on one session is visible to
the other. This is expected given the server holds one bridge process-wide.
- \`not_implemented\`, \`catalog_unavailable\`, and \`sampling_unavailable\`
responses are treated as passes per the agreed test protocol.

/**
* T3 Scenario: End-to-end 2-bedroom apartment build via MCP HTTP server.
*
* Primary path: connect to the shared HTTP server at http://localhost:3917/mcp
* using StreamableHTTPClientTransport (as mandated by the task).
*
* Fallback path: if the shared server is stuck (e.g. "Server already
* initialized" because a previous client is still holding the single session
* slot), fall back to an in-memory MCP server that still exercises the same
* tool surface. We still emit evidence (apartment.json, REPORT.md) and the
* bug is surfaced verbatim in the report.
*
* Run:
* bun packages/mcp/test-reports/t3-scenario/run.ts
