Summary

  • Reconnect dead MCP transports with backoff and single-dial retry.
  • Show reconnecting servers in the TUI command surface with retained tool counts and retry action.
  • Extend tool_search for reconnecting servers that could match, with tier-2 reconnect wait.

Verification

  • Focused reconnect and TUI surface tests; full CI via GitHub Actions.

Fixes CL-8018

Rewrite before merge: oxlint non-null assertion in src/tui/mcp-reconnect-surface.test.ts; rebase after #1067 (tool-search pendingWaitMs overlap). Complements #1082 — land 1081 then 1082.

Keep reconnecting MCP rows up across transient redial failures

Transient redial outcomes stay on the reconnecting row with the next attempt instead of flashing failed; only auth and deterministic misconfiguration stop the loop. The transport close hook and the reconnect consumer land together so death detection actually fires.
