Resolved FEAT-20260905-16: Replaced AgentsPanel mock fixture defaultRoster() with live multi-adapter telemetry feed and process census.

Summary

Replaced hardcoded demo rows (Worker M3, Worker M2, Spec Miner, Explorer) and synthetic token values with live telemetry ingestion from ClaudeTelemetryAdapter, AntigravityTelemetryEngine, OpenAITelemetryAdapter, ProcessTreeSampler, and SessionRegistry.
Implemented TelemetryFeedProvider protocol and LiveTelemetryFeedProvider allowing clean modular DI for production and testing.
Mapped exact 5-tier tokens (inputTokens, cachedReadTokens, outputTokens, thinkingTokens, totalTokens) to SubagentTokenUsage, matching telemetry adapter outputs to the single token.
Implemented updateSubagentsInPlace(_ newItems:) to preserve row identity, positions, and array indices across telemetry refreshes with zero list re-sorting or scroll jumping.
Isolated the 1Hz elapsed timer into a standalone SubagentElapsedView leaf component, preventing timer ticks from invalidating SubagentCardView, TokenGaugeBar, or AgentsPanel.
Verified 6/6 tests passing in AgentsRosterLiveTelemetryTests and full tyrell-appTests passing.
Merged to canonical main on rdmsm4x:~/dev/apps/Tyrell (commit 96e62b8), updated SESSION-STATE.md (commit 6a3a61c), and pushed to fleet (git.ecs0.net) and backup (github.com).
Resolved ticket FEAT-20260905-16 and broadcast to fleet bus.

Sources/tyrell-app/AgentsPanel.swift:
- Removed defaultRoster() from production path; added previewRoster() strictly for previews.
- Added TelemetryRosterData, TelemetryFeedProvider, and LiveTelemetryFeedProvider.
- Added buildRosterItems(from:) fusing Claude, Antigravity, OpenAI, process tree census, and session registry records into unified SubagentItem models.
- Added updateSubagentsInPlace(_:) with index stability and graceful completed state transitions.
- Added SubagentElapsedView standalone leaf view for 1Hz timer scoping.
Tests/tyrell-appTests/AgentsRosterLiveTelemetryTests.swift:
- 6 unit tests covering fixture removal, telemetry fusion, exact 5-tier token matching, in-place update stability, elapsed timer isolation, and host sampling.
SESSION-STATE.md:
- Recorded completion of FEAT-20260905-16 checkpoint.

Unit test suite: swift test --filter AgentsRosterLiveTelemetryTests -> 6/6 tests passed in 10.264s.
Regression suite: swift test --filter tyrell-appTests -> passed with zero errors.

Canonical merge & push: Fast-forward merged into main on rdmsm4x:~/dev/apps/Tyrell and pushed to both fleet (git.ecs0.net:git/apps/Tyrell.git) and backup (github.com/richhdoty/rdmsm4x-dev-apps-tyrell.git).
