Fix Hermes imported history and native tool activity rendering

[eimexdev]

Summary

• Normalize and refresh imported Hermes timelines while preserving source order, turn IDs, timestamps, and history slots.
• Render live and imported Hermes tool calls as native activities with correlated lifecycle events and full tool metadata.
• Remove Hermes-specific title synchronization in favor of standard thread-title generation and projection behavior.
• Add focused coverage for imports, refresh replacement, tool callbacks, activity payloads, and timeline projection.

Testing

• Added and updated focused unit tests across Hermes adapter, bridge client, conversation lifecycle, orchestration, projection, runtime ingestion, and client state.
• Not run locally.

Warning

Review limit reached

@eimexdev, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 1 minute

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Refresh the Hermes child session before reusing it

When an existing external import is opened after the source Hermes session has received more messages, this refresh path reuses t3-${existingThreadId}. The t3agent adapter's /v1/sessions/fork handler only calls db.replace_messages inside if not child_exists, so the response refreshes the T3 projection but the bound Hermes child session that future prompts run against still contains the old copied messages. Please update the existing matching child session's stored messages during refresh, or create a new child session, before opening it.
