Bohan Jiang 53f05cca5e feat(github): fan out PR/check_suite webhooks to all bound workspaces (MUL-4343) (#5218)
* feat(github): fan out PR/check_suite webhooks to all bound workspaces (MUL-4343)

One GitHub App installation can be bound to several workspaces (#4855), but
pull_request and check_suite webhooks were still routed to a single workspace
via resolveWorkspaceForRepo (workspace.repos registry + oldest-binding
fallback). Every workspace but one silently received nothing for a shared repo,
with no way to opt in.

Deliver each repo event to every workspace bound to the installation. Repo
scope is whatever GitHub authorized the installation for; we no longer gate on
the workspace.repos registry (that list means "code the agent clones", not a
webhook subscription). Each workspace independently mirrors the PR, auto-links
against its own issue prefix + github toggles, records check suites against its
own PR mirror, and gets its own realtime broadcast.

- Extract mirrorPullRequestForWorkspace / recordCheckSuiteForWorkspace and loop
  over all installation bindings instead of resolving one workspace.
- Remove the now-dead resolveWorkspaceForRepo / repoIdentityFromURL routing.
- Replace the registry-routing tests with PR + check_suite fan-out tests.

* test(github): out-of-order fan-out test + drop dead query + document multi-workspace delivery (MUL-4343)

Addresses review feedback on the webhook fan-out change:

- Add TestWebhook_CheckSuite_OutOfOrderFansOutToBoundWorkspaces: a check_suite
  that arrives before the PR must stash a pending row per bound workspace, and
  each workspace must drain its own row when the PR fans out.
- Remove the now-unused ListWorkspacesWithRepos query (its only caller was the
  deleted resolveWorkspaceForRepo) and regenerate sqlc; fix the stale
  "picks the target workspace via the repos registry" comment on
  ListGitHubInstallationsByInstallationID.
- Document multi-workspace event delivery in the GitHub integration docs
  (en + zh), including an explicit self-host upgrade note: delivery is now
  keyed on the GitHub connection, so a workspace that relied on the
  code-repository list alone (without connecting GitHub) must connect the
  installation to keep receiving events. This is an intentional, documented
  behavior change — the PR description's earlier "single-binding behavior is
  unchanged" claim was inaccurate and has been corrected.
