* fix(browser): drain download saves and use monotonic cursor for act response
- Add drainPendingDownloadSaves() to wait for in-flight saveAs before sampling
- Use monotonic downloadSeq cursor instead of bounded-list length
- Propagate downloads info in POST /act response for click/batch/evaluate
Fixes#93250
* fix(lint): add braces around single-line if returns
Fixes eslint(curly) failures in drainPendingDownloadSaves and
pickNewDownloads. PR #93307 required CI gate.

* fix(browser): scope act download metadata to action
* fix(browser): broadcast downloads to all active captures to prevent misattribution
When concurrent /act calls overlap on the same page, using
state.actionDownloadCaptures.at(-1) assigned downloads to the wrong
action's capture. Push managed save promises to all active captures
so the triggering action always receives its download metadata.
Also adds regression tests: broadcast-to-all-captures, sequential
capture isolation, and strengthen the dispose test to assert no
re-capture after disposal.
* fix(browser): prevent unhandled rejection when download capture action throws before drain
Move managedSave.catch() before the captures-branch check so the
rejection handler always runs, preventing an unhandled promise
rejection when the action throws before drain() is called. Simplify
the handler by removing the now-dead return + catch at the bottom.
* fix(browser): type downloads in BrowserActResponse, fix lint unused var
- Add optional downloads field to BrowserActResponse type contract so
typed callers of browserAct() can consume the new payload without casts.
- Remove unused afterDispose variable in pw-session tests (lint fix).
* fix(test): correct post-dispose download assertion
capture.promises is not cleared by dispose(), so re-draining a disposed
capture still returns pre-dispose results. This is benign — callers
should drain before disposing. Update the test to assert the actual
behavior (still shows old results, new download not captured).
* test(browser): cover /act download metadata response
* refactor(browser): report action-owned downloads safely
* fix(browser): close action download ownership races
* test(browser): type action download capture mock
