Summary

Flush ready deferred responses before runtime maintenance and again afterward. This prevents a terminal foreground Bash task from waiting behind a synchronous runtime drain before its NDJSON response can be emitted.

The second flush preserves delivery for responses that become ready during maintenance. Runtime maintenance and task execution behavior are otherwise unchanged.

Fixes #172.

Regression coverage

• Adds a pending-response ordering regression: a ready deferred response must be polled and written before configure-warning maintenance runs.
• Updates the periodic-drain polling expectation for the new before/after flush behavior.

Validation

• cargo +nightly-2026-04-29 test -p agent-file-tools pending_response_tests -- --nocapture

• cargo +nightly-2026-04-29 build -p agent-file-tools --release --bin aft
• Direct @cortexkit/aft-bridge smoke against the built binary: configure, Bash launch, terminal status, and output retrieval succeeded.

Summary by cubic

Flush ready pending responses before and after runtime maintenance to unblock terminal Bash NDJSON. Post-write LSP file-change notifications now skip cold starts by notifying only running servers.

• Bug Fixes
  • Flush pending before drain_runtime_events, then flush again after.
  • Removes latency for terminal Bash NDJSON and preserves delivery for responses that become ready during maintenance.
  • LSP: notify_file_changed_if_running avoids starting servers on writes; explicit requests retain lazy startup.
  • Tests: add pending/maintenance ordering and twice-per-tick polling; add LSP no-cold-start regression. Fixes Deferred bash responses can be starved by runtime maintenance after task completion #172.
