fix(tui): remove feature flag, fix stale suggestion, limit to 110 chars

- Remove OPENCODE_EXPERIMENTAL_NEXT_PROMPT gate so suggest always runs
- Use reconcile() in sync store to clear stale suggestion on status change
- Limit suggestion to 110 characters and instruct model to be concise
- Remove temporary debug sidebar panel and plumbing

 - Suggest a useful next step that keeps momentum.
 
 Rules:
-- Output exactly one line.
+- Output exactly one line, 110 characters max. Be concise.
 - Write as the user speaking to the assistant (for example: "Can you...", "Help me...", "Let's...").
 - Match the user's tone and language; keep it natural and human.
