doc: enhance glob pattern documentation in fs.md

Updated the glob pattern section to include detailed syntax explanations, examples, and performance notes. Clarified the `pattern` parameter description and added information on case sensitivity, path separators, and symlink handling. Improved overall clarity and usability of the documentation.

+#### Pattern Syntax
+
+The glob implementation supports the following pattern syntax:
+
+**Basic Wildcards:**
+* `*` - Matches any number of characters within a single path segment
+* `?` - Matches exactly one character
+* `[abc]` - Matches any character in the brackets
+* `[a-z]` - Matches any character in the range
+* `[!abc]` or `[^abc]` - Matches any character not in the brackets
+
+**Globstar:**
+* `**` - Matches zero or more directories recursively
+* `**/*.js` - Matches all `.js` files in any subdirectory
+
+**Brace Expansion:**
+* `{a,b,c}` - Matches any of the comma-separated patterns
+* `{1..5}` - Matches any number in the range (1, 2, 3, 4, 5)
+* `*.{js,ts}` - Matches files with `.js` or `.ts` extensions
+
+**Extended Glob Patterns:**
+* `+(pattern)` - Matches one or more occurrences of the pattern
+* `*(pattern)` - Matches zero or more occurrences of the pattern
+* `?(pattern)` - Matches zero or one occurrence of the pattern
+* `!(pattern)` - Matches anything except the pattern
+
+#### Examples

 ```mjs
 import { glob } from 'node:fs/promises';
 
-for await (const entry of glob('**/*.js'))
-  console.log(entry);
+// Basic patterns
+for await (const entry of glob('*.js'))
+  console.log(entry); // All .js files in current directory
+
+// Recursive search
+for await (const entry of glob('**/*.{js,ts}'))
+  console.log(entry); // All .js and .ts files in any subdirectory
+
+// Brace expansion
+for await (const entry of glob('src/{components,utils}/**/*.js'))
+  console.log(entry); // .js files in src/components or src/utils
+
+// Extended glob patterns
+for await (const entry of glob('test/**/*.+(spec|test).js'))
+  console.log(entry); // Test files ending with .spec.js or .test.js
+
+// Excluding patterns
+for await (const entry of glob('**/*.js', { exclude: ['node_modules/**'] }))
+  console.log(entry); // All .js files except those in node_modules
+
+// Multiple patterns
+for await (const entry of glob(['src/**/*.js', 'lib/**/*.js']))
+  console.log(entry); // .js files in both src and lib directories

+#### Platform Considerations
+
+* **Case sensitivity**: Glob patterns are case-insensitive on Windows and macOS,
+  case-sensitive on other platforms
+* **Path separators**: Forward slashes (`/`) are used in patterns regardless of
+  platform; they are automatically converted to the appropriate separator
+* **Symlinks**: Symbolic links are followed and their targets are included in results
+* **Hidden files**: Files starting with `.` are included in results when explicitly
+  matched, but not when using `*` or `**` patterns
+
+#### Performance Notes
+
+* Results are streamed as an async iterator, allowing for efficient memory usage
+  with large result sets
+* The implementation includes internal caching to avoid duplicate filesystem operations
+* For better performance with large directory trees, consider using more specific
+  patterns to reduce the search scope
