Adds a job-level `if:` guard on `build_main.yml` so that pushes to `master` on a fork (e.g. clicking the "Sync fork" button) do not trigger the full build. Upstream pushes and pushes to non-master branches on forks are unaffected. Generated-by: Claude Code (claude-opus-4-7)

### What changes were proposed in this pull request? Add a job-level `if:` guard on `.github/workflows/build_main.yml` so that the `Build` workflow does not run on pushes to `master` on a fork: ```yaml if: github.repository == 'apache/spark' || github.ref != 'refs/heads/master' ``` ### Why are the changes needed? When a contributor clicks the "Sync fork" button on their fork's `master` (which mirrors `apache/spark`), GitHub records it as a push to `master` and fires `build_main.yml`, running the entire build/test matrix on the fork — duplicating work that already ran upstream. The pattern is already used in the per-branch workflows (`build_branch*.yml` gate with `if: github.repository == 'apache/spark'`); this extends the same idea to `build_main.yml`, but only for the `master` branch on forks so that dev branches on forks continue to be tested. Behavior after this change: | Where | Action | Branch pushed | Job runs? | |---|---|---|---| | `apache/spark` | any push | any | runs (unchanged) | | fork | click "Sync fork" on master page | `master` | **skipped** | | fork | push to dev branch | `<dev-branch>` | runs | | fork | merge `upstream/master` into dev branch, push | `<dev-branch>` | runs | | fork | rebase dev branch on `upstream/master`, force-push | `<dev-branch>` | runs | | fork | push directly to fork's `master` | `master` | **skipped** | The guard is purely branch-name-based — only the literal ref `refs/heads/master` is suppressed. A branch named `master-foo` or `branch-4.x` is unaffected. ### Does this PR introduce _any_ user-facing change? No. CI behavior only. ### How was this patch tested? Inspected the condition manually against each scenario in the table above: - `github.repository == 'apache/spark'` — first clause true → runs. - Fork, `github.ref == 'refs/heads/master'` — both clauses false → skipped. - Fork, `github.ref == 'refs/heads/<dev-branch>'` — second clause true → runs (covers rebases against upstream master and merges of upstream master into a dev branch, since those still push to the dev branch ref). ### Was this patch authored or co-authored using generative AI tooling?

No. CI behavior only.
