fix(glob): sort glob results, files of different folders came in a random order - #13031
glob() returns files in a random order when they're in different folders. Tinyglobby (through fdir) reads folders concurrently, so the files of different folders come in the order their readdir calls finish. On our website's versioned docs, Node.js returned 30 different orders in 30 runs.
Most consumers sort the files again (docs, sidebars, routes, theme aliases), but the blog sorts posts by date only: blog posts with the same date get a random order on each build when each post has its own folder, a common layout (2024-01-01-slug/index.md next to its images).
Repro: a blog-only site with 6 posts dated 2024-01-01, one folder per post. Same content, 6 builds with Node.js 26.13:
build 1: alpha bravo delta charlie foxtrot (sidebar "Recent posts")
build 2: alpha bravo charlie echo foxtrot
build 3: alpha bravo charlie delta foxtrot
build 4: alpha bravo charlie delta echo
...
The sidebar doesn't even show the same posts, and the list and prev/next links change too. With this PR, all builds are identical.
glob() now sorts its results with a plain sort(), which compares UTF-16 code units, so the order doesn't depend on the locale either. The only snapshot change is the order of the pages plugin's loaded content, which then gets sorted into routes anyway.
Notes:
Within a single folder, Node.js already returns files sorted (libuv sorts readdir results, verified on macOS, whose file system returns them unsorted), so files in the same folder were not affected on Node.js.
Bun returns the raw file system order, even within a folder: on Bun, our dogfood blog's same-date posts came out in a different order than on Node.js. This PR fixes that too.
Test Plan
New unit test with 30 post folders: it failed 5 times out of 5 on main, and passes with this fix.
Glob results are now returned in a consistent order, regardless of filesystem or runtime traversal order.
Recursive results are sorted by path, and absolute-path results are ordered relative to the working directory, making repeated searches more predictable.

The glob utility now sorts the paths returned by Tinyglobby before it returns them. Tests verify sorted results for recursive patterns and for absolute paths made relative to a temporary root.
glob sorts Tinyglobby results before returning them. Tests create temporary directory trees and check the order of recursive results and absolute-path results relative to the temporary root.
Glob results are now stable across runtimes. Their order may differ from the documented "files before subfolders" ordering when file and folder names interleave, so confirm which ordering is intended before merging.

Explanation
The title names the main change: glob results are now sorted, fixing the random order of files from different folders. The raw summary confirms that globUtils.ts now sorts the paths returned by Tinyglobby.glob, and that new tests cover concurrent folder reads and absolute-path sorting. The title follows the conventional commit format and is specific, so it is a clear match for the changeset.

- Line 32: Replace the default sort at the `files.sort()` return with a
component-wise path comparison that places files before subfolders, so `z.md`
precedes `a/post.md` while preserving the intended ordering within each
category. Add a mixed-name test covering this case.

Place files before subfolders.
For z.md and a/post.md, sort() puts a/post.md first. The stated crawl-like order puts z.md first. Compare path components with files before directories, and add a mixed-name test.
