fix(git): enable core.longpaths for worktree population (#2746) (#2747)

* fix(git): enable core.longpaths for worktree population

Worktrees live under a deep OpenCode data-dir path, so Windows checkouts
of deeply nested repos failed bootstrap with "Filename too long". Enable
Git core.longpaths before git reset --hard (web + VS Code) and surface
clearer path-length guidance when the filesystem still rejects a path.

Fixes #2746

* chore(vscode): keep ensureWorktreeLongpaths private

Avoid an unused export in the VS Code git service; the helper stays
local to populateWorktreeWithLockRecovery.

@@ -136,6 +136,7 @@ The following functions are internal helpers used by exported functions:
- Fast-create background failures remove OpenCode sandbox metadata for directories that never became Git worktrees, and remove the pre-created directory only if it is still empty. User-created files are never recursively deleted by this cleanup.
- Worktree removal waits for any active create/bootstrap task for that directory before deleting it, preventing a background Git or setup task from restoring removed state or racing filesystem cleanup.
- Worktree bootstrap retries transient `index.lock` conflicts. If the lock remains byte-for-byte and metadata-identical across the retry window, it is treated as stale, removed, and population continues automatically; changing locks are left untouched and reported as failures.
- Worktree population enables Git `core.longpaths` (local repo config plus `-c core.longpaths=true` on `git reset --hard`) so deeply nested checkouts under the managed data-dir worktree root do not fail on Windows MAX_PATH with "Filename too long". Path-component limits that the filesystem itself rejects still fail bootstrap, with a clearer path-length guidance message.
