fix(driver): reset command log nesting after grouped commands in cy.origin

[nnyouung]

• Closes #33162

Additional details

This PR fixes a bug where grouped commands (e.g. within) inside cy.origin() did not reset the Command Log nesting level, causing subsequent groups to appear nested under the previous one.

Root cause
Cross‑origin logs were mutating or inheriting the primary origin’s log group stack (logGroupIds), so the group level did not properly reset after a grouped command finished.

Fix
Prevent cross‑origin logs from mutating primary logGroupIds (ignore groupStart/groupEnd in primary).
Pass originLogGroupLevel/Id metadata from cy.origin to the spec bridge.
Only fill groupLevel/group when missing, preserving already computed values.

Impact
Grouped commands inside cy.origin() now exit correctly, so subsequent commands appear at the expected nesting level.

Note

Medium Risk
Touches core command-log grouping/state logic used broadly across the runner; mistakes could mis-group or mis-render logs, especially in cross-origin scenarios.

Overview
Fixes cy.origin() command log grouping so grouped commands (e.g. within) correctly reset nesting, preventing cross-origin logs from mutating the primary origin’s logGroupIds stack.

This threads originLogGroupLevel/originLogGroupId from the primary cy.origin log group into the spec bridge, and updates Log defaulting logic to scope group tracking by origin, ignore groupStart/groupEnd mutations for cross-origin logs on the primary, and only backfill group/groupLevel when missing. Adds an e2e regression test for group-level reset behavior and a changelog entry.

Steps to test

- Run:
yarn workspace @packages/driver cypress:run --spec cypress/e2e/e2e/origin/commands/log.cy.ts

- (Optional, visual) Open mode:
yarn workspace @packages/driver cypress:open --e2e
Run log.cy.ts and confirm the second 'within' is at the same level as the first.

How has the user experience changed?

Before
After the first grouped command finishes inside cy.origin(), the Command Log group level does not decrease.
Subsequent commands appear incorrectly nested as if still inside the previous group.

After
Grouped commands inside cy.origin() correctly exit their group.
Subsequent commands display at the correct log level.
