refactor(cli): consume shared Functions core

[shrey150]

Summary

Make Browse a thin Oclif adapter over the canonical @browserbasehq/sdk-functions/core library.

• Remove roughly 1,300 lines of duplicate archive, HTTP, polling, scaffold, and local-runtime logic.
• Preserve Browse flags, structured JSON, telemetry classification, exit codes, stderr logging, and signal ownership.
• Carry the SDK-compatible --api-url/-u alias and optional --project-id behavior that fix(cli): align Functions with SDK on v3 CLI #2704 hotfixed only on the V3 release branch.
• Keep bb functions and Browse on one implementation so they cannot drift independently again.

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)

Dependency and release gate

This PR depends on sdk-functions-node #40, which exposes the shared core. The catalog is temporarily pinned to exact tested SDK commit c74bea65c3dd645470e0fc80e65cfff283310665; the Git dependency requires its prepare build and a temporary pnpm allowBuilds entry.

Keep this PR draft and do not merge or publish Browse from the commit pin. After @browserbasehq/sdk-functions@1.1.0 is published:

1. Replace the catalog pin with ^1.1.0.
2. Remove the temporary allowBuilds entry and TODO.
3. Regenerate the lockfile from a clean install.
4. Rerun frozen install, the full matrix, package/consumer checks, and fresh npm/pnpm scaffold live-cloud smokes.

Review boundary

The SDK core owns scaffolding, archive rules, Functions HTTP operations, project inference/override, build/invocation polling, local runtime, and typed failures. This PR owns only Oclif flags, Browse output/telemetry/error adaptation, signals, and dependency wiring. A contract test verifies that importing the /core subpath does not execute the Commander CLI.

E2E verification

Flow	Observed result
SDK lint/build/unit	Passed; 63/63 SDK tests
SDK packed-tarball suite	58/58 across ESM, CJS, declarations, CLI, scaffold, manifest, and TS consumer
SDK live templates	4/4 starter templates scaffolded, installed, published, built, and invoked
Stagehand frozen install with exact SDK pin	Passed under pnpm 11.10
Current-head Browse lint/build	Passed on 373e24061e
Current-head full Browse suite	27 files / 386 tests passed
Local dev with real credentials and no project env	Connected, invoked a managed session, returned Example Domain, and cleaned up
Browse publish + synchronous invoke	Build completed; invocation returned shared-core-ok
Async invoke + independent status lookup	PENDING progressed to COMPLETED with the same result
Cross-host invoke	Exact SDK #40 bb CLI invoked the Function published by Browse and got the same result

Live validation used synthetic functions and public targets. Secrets, account identifiers, resource IDs, and connection URLs are omitted. A fresh registry install of eventual 1.1.0 remains mandatory and is why this PR stays draft.
