Pure refactors with no behavior change, mostly reusing existing helpers
and dropping duplicated or dead code. Net −222 lines.
- Reuse existing helpers instead of inlined copies: `getIssueIndex`,
`NewLabel`, `ToCommitUser`, `GetPackageFileDescriptors`,
`util.SplitTrimSpace`
- Merge copy-pasted blocks in review comment deletion, project deletion
and the pre/post-receive hook templates
- Drop dead code: an error `toStringKeys` never returned, impossible
`bytes.Buffer` write errors, redundant nil-map branches, a `base64`
wrapper
- Use stdlib where it fits: `strings.Cut`, `bytes.IndexAny`,
`cmp.Compare`, `min`/`max`, `slices.Concat`, map lookups instead of key
scans
Create delegate hook files and directories without group or other write
access, including correcting existing hook directories.

Rename functions "util.Remove" (remove.go) to "util.RemoveWithRetry"
(file_retry.go) and add comments to clarify their behaviors, also add
tests.
Refactor callers: when no concurrent access (cmd cli, migration, app
init, test), use "os.Xxx" directly.
More details are in `modules/util/file_retry.go`
By the way, clean up OS (windows) detection, make FileURLToPath test
always run
before: gitrepo vs git packages
after: git package fully handle all git operations
by the way, use `WithRepo(repo)` instead of `WithDir(repo.Path)` to hide
path details.
benefits:
1. remove all unnecessary wrappers, developers no need to struggle with
"which package should be used"
2. simplify code, RepositoryFacade can (will) be used everywhere, all
"path" details are (will be) hidden
