When claude-code emits a rate_limit_event with status != allowed_warning,
the subprocess waits internally for the limit to clear before retrying. No
PTY output flows during that window, so the inactivity timeout in the PTY
runner would fire and kill the agent — mergemaster especially, whose
15-minute inactivity window is shorter than typical rate-limit backoffs.
Track `block_until = Some(reset_at)` on hard-block events and add the
remaining time-until-reset to the per-iteration recv timeout. Once reset_at
passes (or an earlier emit arrives), the extension implicitly drops to 0
and the base inactivity timeout resumes. Turn/budget counts aren't affected
— they come from the session log and only advance when API calls actually
complete, so a stalled retry doesn't burn either.
Regression test in agents/pty/mod.rs spawns a script that emits a hard-block
with reset_at = now+3s, sleeps 3s, then exits, with inactivity_timeout_secs
= 1. Without the fix the runner kills the script at 1s; with the fix the
deadline is bumped past the sleep and the run completes cleanly.

claude CLI 2.1.97 strictly enforces that --include-partial-messages
requires --print/-p to be set. The resume path skipped -p when the
prompt was empty (which is the common case on respawns when there's
no fresh failure context to inject), so the spawned claude process
saw `--resume <sid> ... --include-partial-messages` without -p and
exited with code 1: "include-partial-messages requires --print and
--output-format=stream-json".
Net effect: every coder respawn with prior_sessions > 0 and empty
prompt was failing immediately, looking exactly like a rate-limit
(empty agent log, zero tool calls). 819 hit retry-limit (4/3) and
got marked blocked because of this — not because of any actual code
or rate-limit issue.
Fix: always pass `-p <prompt>` on resume, even with empty prompt.
