The pre-commit workflow used `actions/checkout` with `fetch-depth: 0`, which fetches every branch in the repo (thousands), making checkout take ~8 minutes. The --from-ref/--to-ref diff only needs full history for the branch being compared against. Replace it with a default shallow checkout plus a targeted fetch of just the base branch, deepened via --unshallow (guarded for already-complete repos) and with --filter=blob:none since `git diff --name-only` only needs trees. This keeps the three-dot merge base resolvable for both PR and push events.
The pre-commit checkout took ~8 minutes. CI logs showed the cost is not branch enumeration but downloading the blob pack for one snapshot of the monorepo: a single commit's working tree is ~43,757 blobs (~9 GB), and a depth-1 fetch of one ref takes ~6 minutes on its own. Switch checkout to a blobless partial clone (`filter: blob:none`) with a minimal sparse-checkout, then widen the sparse cone to only the projects touched by the diff. Blobs for untouched projects are never fetched, so a typical PR fetches megabytes instead of ~9 GB. Project-level granularity keeps each project's configs and local pre-commit hook scripts present even when they live in sibling directories. The base branch is still fetched on its own (commits/trees only) so the three-dot --from-ref/--to-ref merge base resolves without fetching every branch.

Throwaway test PR to validate the blobless sparse-checkout pre-commit workflow (#8863). Based on that branch (so the new workflow runs); the test commit changes only a doc.
Path under test:
projects/hipdnn/docs/TEST_sparse_dirty.md(awk cone ->projects/hipdnn).Expected pre-commit result: FAIL (trailing-whitespace / end-of-file-fixer).
