test(evals): exercise the workspace V4 CLI

[shrey150]

Summary

Make workspace evals and packaging consume the V4 Browse CLI proven in #2835.

• Point Stagehand evals at the workspace Browse package instead of published Browse 0.9.5.
• Update native and external-agent adapters to the current Browse command grammar.
• Keep eval session names within Unix socket limits, restrict the wrapper to driver commands, and clean daemons up on abort/signals.
• Add command-mapping and real wrapper-process coverage.

The Browse migration changeset now belongs to #2835, the first complete supported-parity head; this PR has no changeset in its own diff. The unrelated eval CLI --verbose changes from the old draft are intentionally excluded.

Stack (#2872)

1. chore(cli): import Browse V3 baseline #2833 — exact Browse V3 baseline import
2. refactor(cli): migrate Browse runtime and commands to Stagehand V4 #2834 — Stagehand V4 runtime and standard command parity
3. feat(cli): restore cursor overlay through page.evaluate #2869 — CLI-owned cursor overlay
4. fix(cli): restore V3 network capture through a CDP sidecar #2849 — CLI-private CDP sidecar; V3 network parity
5. refactor(cli): remove coordinate XPath return flag #2835 — remove --return-xpath; supported V3 parity/release checkpoint
6. test(evals): exercise the workspace V4 CLI #2838 — eval and packaging integration
7. fix(cli): persist context names in Browserbase #2839 — managed Context names (fast-follow)
8. refactor(cli): consume shared Functions core #2701 — shared Functions core consumer (fast-follow)

Review boundary

This is a consumer/integration layer, not another runtime-parity layer. Its diff is limited to eval adapters, their tests, workspace dependency wiring, and the lockfile.

E2E verification

Flow	Observed result
Isolated packed Stagehand + Browse consumer	Browse resolved the packed Stagehand package from isolated node_modules; install audit reported 0 vulnerabilities
Installed node_modules/.bin/browse in real Chromium	Open/snapshot/fill/focus/press/bare type/ref click/DOM reads passed; final output Submitted: TypedByBareCommand
Installed cursor + coordinate mouse	Cursor DOM moved to 211px, 233px, with SVG present
Real BrowseCliTool subprocess	Input AdapterBareType produced Submitted: AdapterBareType; daemon cleanup succeeded
Integration proof-commit typecheck	Passed on 5a9ab832b2 after a clean frozen install and dependency-closure build
Integration proof-commit eval suite	58 files / 446 tests passed
Integration proof-commit eval build	ESM and CLI builds passed
Changeset status	Valid; Browse minor bump inherited from #2835, no migration changeset owned here

The packed consumer and wrapper-process smokes use real processes and Chromium rather than mocked command handlers.
