* fix(sources/filesystem): order resume comparison by path component
When resuming a filesystem scan, scanDir compared the directory path
against the stored resume point with a raw string comparison
(`path < resumeAfter`). Raw comparison does not match the depth-first
traversal order produced by os.ReadDir, because the separator '/' (0x2F)
sorts after characters that are valid inside a path component such as
'-' (0x2D) and '.' (0x2E).
So with sibling directories where one name is a prefix of the other,
e.g. `blue-team` and `blue-team-deprecated`, resuming inside `blue-team`
made scanDir evaluate `"/root/blue-team-deprecated" < "/root/blue-team/file"`
as true and skip `blue-team-deprecated` entirely, silently dropping every
file beneath it.
Compare the paths component by component instead, which matches the order
os.ReadDir returns entries in ("blue-team" before "blue-team-deprecated").
Adds an integration test for the prefix-sibling case and a unit test for
the comparison helper.
Closes#5039
* refactor(sources/filesystem): simplify comparePathsForResume with slices.Compare
Replace the manual component-wise loop with slices.Compare over the
split path components. Equivalent ordering (a shared-prefix ancestor
path still sorts before its descendants) with a smaller body.
