fix(acp): Gemini ACP protocol fixes and multi-session architecture (#901)
* fix(cli): add missing X-GoClaw-User-Id header to gateway client
* feat(acp): comprehensive integration with Gemini ACP protocol
- Support nested JSON-RPC notification structures
- Add robust streaming text collection and mapping
- Increase handshake timeout to 60s for heavy model initialization
- Fix WebSocket user_id authentication and schema v47 compatibility
- Allow Google/GCP environment variables for ACP subprocesses
* refactor(acp): multi-session architecture with session tracing and temp session cleanup
- One shared Gemini process, multiple ACP sessions per process (one per goclaw conversation)
- resolveSession: per-key mutex prevents TOCTOU race on concurrent session creation
- Respawn detection via proc pointer comparison; session/load fallback after crash
- sessionReaper: purges ACP sessions idle >30min; temp- sessions purged immediately on completion
- WithGoclawSession context propagation: goclaw session key appears alongside ACP sid in all logs
- dispatchUpdate: Gemini agent_message_chunk protocol mapping normalized here
- session_test.go: full coverage of multi-session API (Initialize, NewSession, Prompt, Cancel, dispatch)

* fix(acp): align with ACP protocol standard (SDK v0.16.1)
- InitializeRequest: "capabilities" → "clientCapabilities" (standard field name)
- LoadSessionRequest: add mcpServers field (required by standard)
- mapStopReason: add standard stop reasons (max_tokens, cancelled)

* fix(acp): address review findings from PR #901
- B1: Restore RequiredSchemaVersion to 55 (was incorrectly set to 47)
- S1: Move X-GoClaw-User-Id header outside token check
- S2: Add env gate (ACP_GEMINI_E2E) to Gemini E2E test
- S3: Fix tab indentation in jsonrpc.go writeMessage
- Build: Extract Pdeathsig to platform-specific files for cross-platform build
* fix(acp): address S4-S7 review findings
S4/S5: Send session/cancel before purging sessions locally
- purgeSession() now cancels ACP session before deleting map entry
- sessionReaper() sends cancel notification for idle sessions
- Updated comments to reflect actual behavior
S6: Tighten GOOGLE_/GCP_ env var filtering
- Add GOOGLE_, GCP_ back to sensitiveEnvPrefixes
- Add allowedEnvExact for safe vars: GOOGLE_API_KEY,
GOOGLE_APPLICATION_CREDENTIALS, GOOGLE_CLOUD_PROJECT, GCP_PROJECT
S7: Propagate ACP errors to callers
- Chat/ChatStream now return err alongside ChatResponse
- Enables upstream retry logic and error metrics
