Phase 2 of the Scalable Approach for Adding New IDE Session Types RFC, tracked in #27410. Adds a session_counts map to Stats on the Agent API, so an agent can report a count per app name instead of the four fixed fields, which are now marked deprecated. Bumps the API to v2.11. - coderd normalizes names on ingest, caps distinct entries, and sums the overflow under unknown, so an arbitrary client name cannot blow up cardinality. - Agents predating v2.11 set the fixed fields instead, never both, and the ingest path falls back to them. Nothing sends session_counts yet. The agent starts populating it in #28338.
