* ♻️ refactor: use incremental diff for snapshot messages to prevent OOM

Replace full messages/messagesAfter duplication per step with baseline + delta approach:
- Step 0 and compression resets store full messagesBaseline
- Other steps store only messagesDelta (new messages added)
- Strip llm_stream events from snapshot (not useful for post-analysis)
- Strip messages from done.finalState (reconstructible from delta chain)
- Strip duplicate toolResults from context.payload
- Reduce context_engine_result event size by removing messages and toolsConfig
- Add reconstructMessages() utility for rebuilding full state from delta chain
- AiAgentService constructor now accepts runtimeOptions for DI

* ♻️ refactor: add incremental toolset delta for snapshot

- Store operationToolSet as toolsetBaseline in step 0 only (immutable)
- Track activatedStepTools changes via per-step activatedStepToolsDelta
- Strip operationToolSet/toolManifestMap/tools/toolSourceMap from done.finalState
- Add reconstructToolsetBaseline() and reconstructActivatedStepTools() utilities

* 🐛 fix: correct snapshot delta recording and restore context-engine output

- P1: messagesDelta now always stores only appended messages (afterMessages.slice),
  fixing duplication when isBaseline was true (step 0 / compression reset)
- P2: Restore context_engine_result.output (processedMessages) — needed by
  inspect CLI for --env, --system-role, and -m commands
- Add P1 regression test for message deduplication
