fix(parser): harden Agent subagent state machine, file matching, query performance and streaming child grouping

Browse Source 
- Codex: decouple active_agent_count decrement from close_agent target
  parsing and reset counter on turn_context to prevent main assistant
  messages from being swallowed when close_agent events are malformed
- Codex: use exact filename match with separator-aware fallback and
  sorted candidates for deterministic subagent session file resolution
- Codex/OpenCode: truncate subagent tool call previews to 500 chars
- OpenCode: batch-load all subagent tool calls in a single SQL query
  instead of per-task N+1 queries to avoid slow detail page loads
- Streaming: restrict positional child grouping fallback to in-progress
  agents only, preventing top-level tool calls from being incorrectly
  folded into completed Agent cards
- Tests: update Claude context window assertions to match 1M default
