Ingest Claude Code sub-agent sessions; fix model filter on MCP views#4

Sub-agent (Task tool) turns are written to ~/.claude/projects/<project>/<sessionId>/subagents/agent-*.jsonl and were never discovered by the ingester, so usage from spawned agents (often claude-haiku-4-5) was invisible in totals, charts, and breakdowns. The parser now globs those files and rolls their messages into the parent session. The /api/mcp endpoint was missing the `model` query parameter entirely, so the model filter was silently dropped on the "by mcp server" and "by mcp tool" breakdowns. /api/breakdown_series did accept it but filtered on sessions.model (last observed), which is wrong when a session uses multiple models. Both now filter per-message via the assistant turn that issued the call (matching mcp_calls.source_file + source_line to messages.source_file + source_line), consistent with how /api/stats already filters.

It was missing from the function signature, so the model filter was silently dropped on the "by mcp server" and "by mcp tool" breakdowns.modelper-message, not per-session. Both/api/mcpand the MCP branch of/api/breakdown_seriesfilter via the assistant turn that issued the call (mcp_calls.source_file+source_line↔messages.source_file+source_line), matching how/api/statsfilters. Previouslybreakdown_seriesfiltered onsessions.model, which is the session's last-observed model and wrong when a session mixes models (e.g. parent Opus + sub-agent Haiku).Test plan
