Sort bookmark names alphabetically and add unit tests

[danieldelcore]

Motivation

• Ensure bookmarks are displayed and picked in a predictable, user-friendly alphabetical order.

Description

• Add bin/bookmarks.js exporting sortBookmarksByName that performs a locale-aware, case-insensitive, numeric-aware sort of bookmark entries.
• Use sortBookmarksByName in listBookmarks and pickAndRunBookmark inside bin/index.js so listed names and the interactive picker are sorted.
• Add unit tests in test/bookmarks.test.mjs to validate alphabetical, case-insensitive, and numeric ordering behavior.
• Add a changeset file .changeset/silent-stingrays-flash.md documenting the patch.

Testing

• Added unit tests for sortBookmarksByName and ran the test suite with vitest; the new tests passed.
• Ran npm test (which invokes the automated test runner) and the test run succeeded.
