What changed in this PR
Introduces an opt-in setting to disable pull request stack functionality by default, and gates stack-related UI/actions based on that setting.
Changes:
- Added
githubPullRequests.experimental.stackssetting (defaultfalse) plus a sharedareStacksEnabled()helper. - Disabled/guarded stack-dependent behaviors in the PR tree, PR overview/webviews, merge-stack, unstack, and create-PR stack flows.
- Added test coverage and a reusable test mock for the new stacks setting.
