Update the dev.md agent skill to work with the patch-based workflow: (1) Accept task via piped JSON or CLI arg (task show t-123 | agentd run dev.md). (2) Create branch t-XXX in dev worktree, or check it out if it exists (for revisions). (3) Make exactly one commit with Task-Id trailer. (4) On revision: amend the existing commit, don't create new ones. (5) Force-push the branch. (6) Increment patchset_count. (7) Set task status to 'review'.
Rewrote Omni/Ide/Workflows/dev.md for patch-based one-task-one-commit flow: branch t-XXX, amend revisions, Task-Id trailer requirement, and status handoff to review.
