feat(pull-requests): quick actions follow each host's capabilities, not GitHub

[juliusmarminge]

The shift-held quick actions (close, merge, mark ready, reopen) and the drag-to-close sweep on the pull requests page were offered only for provider === "github". So were the quick actions on a thread's linked pull requests, which also sniffed the host from the URL. Nothing behind them is GitHub-only. They run the ordinary runAction, which every host's provider implements and declares in capabilities.actions. The gate came in with #15549, which was only verified on GitHub.

Fix

• Contract. PullRequestProviderSummary (one per host in the list response) gains an optional actions. The server fills it from that host's provider capabilities, the same way it already fills searchesOnHost.
• Pull requests page. pullRequestHostActions and pullRequestQuickActions (in pullRequestList.logic) decide a row's quick actions: what its state allows, narrowed to what its host can do. Rows, the close sweep and the close batch use them instead of the "github" checks.
• Thread panel. A linked PR carries no host summary, so its actions come from the host's client definition. The definition gains changeRequestActions.
• One list per host. Each server provider now builds capabilities.actions from its client definition's changeRequestActions, so the two lists can't drift apart.
• Older servers. A server that sends no actions keeps today's behavior: GitHub only.

Behavior change (intended). Quick actions now show on every host, limited to what that host supports:

Host	Open	Draft	Closed
GitHub, GitLab, GitCafe	Close, Merge	Close, Ready	Reopen
Azure DevOps	Close, Merge	Close, Ready	Reopen
Forgejo	Close, Merge	Close	Reopen
Bitbucket	Close, Merge	Close	(none)

Merge still goes through the existing on-click detail read. That read checks the viewer's permission and refuses stacked PRs, so viewer permissions and stacks are respected the same way on every host.

Not in scope. Account routing (pullRequestRouting.ts) stays GitHub-only. Only GitHub implements getRoutingIdentity, and the contract types its result as provider: "github".

Verification

• npx tsc --noEmit -p . is clean in contracts, client-runtime, every source-control-* package, server, web and mobile.
• vp test run passes on apps/web/src/components/pullRequest, apps/web/src/routes, the contracts tests, every source-control-* package and client-runtime. One new logic test covers offering each host's reported actions and the fallback for older servers.
• Server tests for pullRequest and sourceControl pass under unshare: 11 files, 296 tests. That includes a new test that the list reports each host's actions.
• vp lint on the touched files reports 0 errors, knip is clean, and the Effect-shortcut grep over the added lines finds nothing.
• I didn't start a dev server or open a browser, so this hasn't been checked in a running app.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR expands existing quick-action UI and close-sweep behavior from GitHub to several source-control hosts and linked pull requests, enabling externally visible merge, close, ready, and reopen operations in new contexts. The cross-package behavior change and its side effects warrant human review.

📝 Walkthrough

Walkthrough

Source-control clients declare supported pull request actions. Server provider summaries include those actions. The web interface uses them to select displayed actions and determine which pull requests qualify for close sweeps.

Changes

Host-supported pull request actions

Layer / File(s)	Summary
Declare host action capabilities packages/source-control-core/src/client/definition.ts, packages/source-control-*/src/client/definition.ts	Client definitions declare supported pull request actions. The unknown client declares an empty action set.
Advertise host actions packages/contracts/src/pullRequest.ts, packages/source-control-*/src/server/*PullRequestProvider.ts, apps/server/src/pullRequest/PullRequestService.ts, apps/server/src/pullRequest/PullRequestService.test.ts	Providers use client definitions for their action capabilities. Configured-host summaries include supported actions. The Bitbucket test checks that the summary reports its actions.
Select and apply host-supported actions apps/web/src/components/pullRequest/pullRequestList.logic.ts, apps/web/src/components/pullRequest/pullRequestList.logic.test.ts, apps/web/src/routes/_chat.pull-requests.tsx, apps/web/src/components/pullRequest/{PullRequestRow,PullRequestSpeedActions,ThreadPullRequestsPanel,usePullRequestActions}.tsx, apps/web/src/components/pullRequest/pullRequestChecks.test.tsx	The interface resolves actions by host and pull-request state, then passes eligible actions to rows. Close sweeps include open, non-pending entries when their host supports closing.
