feat(chat): derive activity indicator from per-session state and unify provider lifecycle events

Replace the chat processing banner with a minimal activity indicator and rebuild the state model underneath it. The old banner was driven by five overlapping pieces of state (isLoading, canAbortSession, claudeStatus in the chat, plus two app-level Sets updated in lockstep through four callbacks) that had to be kept in sync imperatively. Because completion and status events mutated the *viewed* session's flags regardless of which session they belonged to, a background session finishing could hide the indicator for a still-running session, returning to a finished session could briefly show a stale banner, and a late status reply could override a newer request. The fix is structural rather than patch-by-patch: a single Map<sessionId, {statusText, canInterrupt, startedAt}> in useSessionProtection is now the only source of truth for "this session is working". The indicator, stop button, composer streaming state, and session protection are all derived from the viewed session's entry on render, so there is no stale local copy to restore or reset when switching sessions. A PENDING_SESSION_ID sentinel covers the window before a new conversation receives its real session id. Terminal events delete the entry atomically, which is why the indicator disappears the instant the final chunk arrives. Stale check-session-status replies are discarded via an ifStartedBefore guard (an idle reply older than the entry's startedAt describes a previous request, not the current one). The second half unifies the provider lifecycle contract, because the frontend could not be made race-free while each provider terminated differently: - cursor emitted complete twice per run (result line + process close), which double-played the completion sound and let a late close-complete clear a newer request's indicator - aborts produced two completes (the abort-session reply plus the provider's own non-aborted one), so cancelling a run played the celebration sound - codex omitted exitCode; others attached ad-hoc fields (resultText, isError, isNewSession) the client had to know about - claude/codex failures ended with only an error event while gemini/cursor also emit kind:'error' for mid-run stderr noise, so 'error' was ambiguous between "the run died" and "a process wrote to stderr" Every run now ends with exactly one complete built by createCompleteMessage() ({sessionId, actualSessionId, exitCode, success, aborted}); abort-session sends it on behalf of cancelled runs and providers detect the abort and skip their own. error is demoted to an informational row, so stderr noise no longer kills the indicator mid-run, and the client celebrates only success: true completes.

 ### Chat Notes

-1. `abort-session` returns a normalized `complete` message with `aborted: true`.
-2. `check-session-status` returns `{ type: "session-status", isProcessing }`.
-3. Claude status checks can reconnect output stream to the new socket via `reconnectSessionWriter`.
+1. **Unified terminal lifecycle**: every provider run ends with exactly one `complete` message built by `createCompleteMessage()` (`server/shared/utils.ts`), regardless of provider: `{ kind: "complete", sessionId, actualSessionId, exitCode, success, aborted }`. Failed runs emit an informational `error` message first, then the terminal `complete` with `success: false`. Mid-run `error` messages (e.g. stderr output) are non-terminal; the frontend only treats `complete` as end-of-run.
+2. `abort-session` sends the terminal `complete` (`aborted: true`) on behalf of the cancelled run; providers detect the abort and skip their own `complete` so the client sees exactly one.
+3. `check-session-status` returns `{ type: "session-status", isProcessing }`.
+4. Claude status checks can reconnect output stream to the new socket via `reconnectSessionWriter`.

Haileyesus	afc717e69e	feat(chat): derive activity indicator from per-session state and unify provider lifecycle events Replace the chat processing banner with a minimal activity indicator and rebuild the state model underneath it. The old banner was driven by five overlapping pieces of state (isLoading, canAbortSession, claudeStatus in the chat, plus two app-level Sets updated in lockstep through four callbacks) that had to be kept in sync imperatively. Because completion and status events mutated the viewed session's flags regardless of which session they belonged to, a background session finishing could hide the indicator for a still-running session, returning to a finished session could briefly show a stale banner, and a late status reply could override a newer request. The fix is structural rather than patch-by-patch: a single Map<sessionId, {statusText, canInterrupt, startedAt}> in useSessionProtection is now the only source of truth for "this session is working". The indicator, stop button, composer streaming state, and session protection are all derived from the viewed session's entry on render, so there is no stale local copy to restore or reset when switching sessions. A PENDING_SESSION_ID sentinel covers the window before a new conversation receives its real session id. Terminal events delete the entry atomically, which is why the indicator disappears the instant the final chunk arrives. Stale check-session-status replies are discarded via an ifStartedBefore guard (an idle reply older than the entry's startedAt describes a previous request, not the current one). The second half unifies the provider lifecycle contract, because the frontend could not be made race-free while each provider terminated differently: - cursor emitted complete twice per run (result line + process close), which double-played the completion sound and let a late close-complete clear a newer request's indicator - aborts produced two completes (the abort-session reply plus the provider's own non-aborted one), so cancelling a run played the celebration sound - codex omitted exitCode; others attached ad-hoc fields (resultText, isError, isNewSession) the client had to know about - claude/codex failures ended with only an error event while gemini/cursor also emit kind:'error' for mid-run stderr noise, so 'error' was ambiguous between "the run died" and "a process wrote to stderr" Every run now ends with exactly one complete built by createCompleteMessage() ({sessionId, actualSessionId, exitCode, success, aborted}); abort-session sends it on behalf of cancelled runs and providers detect the abort and skip their own. error is demoted to an informational row, so stderr noise no longer kills the indicator mid-run, and the client celebrates only success: true completes.
