Skip repository hooks during filtered bundle synthesis

[Copilot]

Filtered bundle generation applies the patch in a temporary detached worktree, which invokes repository post-checkout (and apply-patch) hooks. In a Git LFS repository without git-lfs on PATH, git worktree add fails with This repository is configured for Git LFS but 'git-lfs' was not found on your path, and the handler surfaces this as Branch ... does not exist locally even though the branch and its patch are valid.

Changes

• actions/setup/js/generate_git_bundle.cjs: allocate an empty temporary hooks directory and run the internal git worktree add, git am --3way, and git worktree remove with -c core.hooksPath=<empty-dir>; remove the directory alongside the worktree in finally.
• actions/setup/js/generate_git_bundle.test.cjs: regression test against real Git that installs a post-checkout hook exiting 2 and requires incremental filtered bundle generation to succeed.
• Changeset: patch entry.

const tempHooksDir = fs.mkdtempSync(path.join(os.tmpdir(), "gh-aw-filtered-bundle-hooks-"));
const noHooksArgs = ["-c", `core.hooksPath=${tempHooksDir}`];
execGitSync([...noHooksArgs, "worktree", "add", "--detach", tempWorktree, baseCommitSha], { cwd });
execGitSync([...noHooksArgs, "am", "--3way", patchResult.patchPath], { cwd: tempWorktree });

Only these internal synthesis operations bypass hooks; user-facing checkout/commit paths are untouched.

• Fixes Filtered bundle generation runs checkout hooks and misreports valid branches as missing #50670

@copilot add git integration test

[Copilot]

@copilot add git integration test

Added a generateGitBundle hook bypass describe block to git_patch_integration.test.cjs (commit ce8b2f7). The test sets up a real git repository, installs a post-checkout hook that exits 2 (simulating absent git-lfs), and asserts that generateGitBundle in incremental mode still produces a valid bundle containing the expected refs.

@copilot The latest request was addressed, but this PR still needs follow-through. Please refresh the branch if needed and run the pr-finisher skill before handing back to maintainers.
