Adds end-to-end symlink syncing driven by the "Symbolic links" setting
(real / follow / skip; default real), building on the earlier detection.
- Pull: on desktop with "real", a remote symlink is recreated as a real OS
link via Node fs (utils/symlink.ts, guarded by Platform/FileSystemAdapter);
otherwise the target path is written as content.
- Push: GitHubService.pushSymlink commits a real symlink blob (mode 120000)
through the Git Data API (blob -> tree -> commit -> ref). getFile now
reports isSymlink/symlinkTarget.
- Config 防呆: only GitHub offers "real"; on GitLab/Gitea (no API to create
symlinks) "real" resolves to "skip" via getEffectiveSymlinkHandling.
- Safety: a "follow" push never overwrites a detected remote symlink with a
regular file; it is skipped with a notice.
- Docs: docs/symlink-handling.md plus a README settings note.
Lint is satisfied without disables (Electron global require, minimal Node
type shims). Adds tests for getFile detection, the pushSymlink Git Data
sequence, and the remote-symlink push guard.
