refactor(daemon): apply the seam addendum after #1876 was re-scoped

Two edits, per find's ADDENDUM.md:

1. `includeRects` returns to `buildRuntimeCaptureInput`. It was removed from
   #1876 as unconsumed; the selector capture path is genuinely its first
   consumer (a Web rect capture requests bounds explicitly), so it lands here
   under the same rule that moved the seam. `snapshot`/`diff` pass nothing.

2. The per-capture `signal` is dropped, not restored. `CaptureSnapshotInput`
   has no such field on this stack — it moved to `wait` (#1875) with the
   regression that proves per-poll abort and quiescence. `get` captures once
   per resolution and never polls, so nothing here needs it. The seam test and
   fixture coverage for it moves with the contract rather than being kept
   against a field that no longer exists.
