Sequence guard doesn't filter sequenceNumber: 0 mid-task—progress bar will reset.

The renderer's sequence guard at line 435 of apps/frontend/src/renderer/stores/task-store.ts only drops updates when incomingSeq > 0 && currentSeq > 0 && incomingSeq < currentSeq. When the main process sends sequenceNumber: 0 (as this fix does), the condition incomingSeq > 0 is false, so the guard is bypassed entirely. The update proceeds to merge at line 451-454, applying phaseProgress: 0 to the task state.

This means every XState mid-task transition (e.g., planning → coding while the agent is running) will reset the progress bar to 0%, which is the exact regression the PR commit message claims to avoid. The sequence guard has no logic to treat sequenceNumber: 0 as a special sentinel that should be dropped when currentSeq > 0.

Either update the renderer's guard to explicitly drop sequenceNumber: 0 when currentSeq > 0:

if ((incomingSeq === 0 && currentSeq > 0) || (incomingSeq > 0 && currentSeq > 0 && incomingSeq < currentSeq)) {
  return t; // Skip update
}

Or use a distinct sentinel value (e.g., sequenceNumber: -1) with explicit renderer handling.

In `@apps/frontend/src/main/task-state-manager.ts` around lines 365 - 381, The
renderer's sequence guard (the check using incomingSeq and currentSeq in the
task-store update path that merges IPC_CHANNELS.TASK_EXECUTION_PROGRESS
payloads) must treat sequenceNumber=0 as a special sentinel so mid-task updates
don't reset progress; update that guard (the condition that currently reads
incomingSeq > 0 && currentSeq > 0 && incomingSeq < currentSeq) to also skip when
incomingSeq === 0 && currentSeq > 0 (or alternatively change the main-process
sender safeSendToRenderer for IPC_CHANNELS.TASK_EXECUTION_PROGRESS to use a
distinct sentinel like -1 and update the renderer's guard to handle that
sentinel), ensuring variables referenced (incomingSeq/currentSeq and the
TASK_EXECUTION_PROGRESS handler that merges phaseProgress/overallProgress) are
adjusted accordingly.
