Small utils refactors to make subsequent PRs cleaner.
Minor tweaks to how we determine / handle the xtool build version
The default TemporaryDirectory locations have changed to more stable paths, similar to the ones Bazel uses.
on macOS we now default to \(URL.cachesDirectory)/sh.xtool (usually ~/Library/Caches/sh.xtool)
on Linux we (continue to) default to ${XDG_CACHE_HOME:-~/.cache}/xtool
we no longer respect $TMPDIR. One can still use $XTL_TMPDIR to override.
How was it tested?
Made sure the caches directory is what we expect
Checked xtool --version

Summary by CodeRabbit
New Features
Version information now distinguishes clean builds from builds with uncommitted changes, displaying a -dirty suffix when applicable.
Nonblocking file-locking operations are now available to external consumers.
Changes
Version reporting uses XTOOL_VERSION when set; otherwise, it uses available Git tag or commit information.
Temporary files now use the tool’s cache directory, honoring XTL_TMPDIR and platform cache settings. On Linux, the location follows XDG_CACHE_HOME when it is an absolute path; otherwise, the user cache directory is used.
TMPDIR is no longer used to select the temporary-file location.
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The pull request separates version strings from dirty-state reporting, adds a Swift version value, changes temporary-directory cache selection, and makes file-descriptor locking APIs public.
Changes: Version reporting
Layer / File(s)
Summary
Build-time version metadata Package.swift
The Git fallback no longer appends a dirty suffix. A separate C definition records whether the repository has uncommitted changes.
C version and dirty-state queries Sources/CXKit/include/version.h, Sources/CXKit/version.c
CXKit declares and implements xtl_has_uncommitted_changes().
Swift version value Sources/XCLIUtils/CommandVersion.swift, Sources/XToolSupport/XTool+Version.swift
CommandVersion stores the version and dirty state. XTool.version now returns this value, whose description appends -dirty when appropriate.
XToolCache.directory selects a cache location based on platform and environment. TemporaryDirectoryRoot uses that location. .gitignore excludes the root-level /xtool path, and the debugging documentation removes TMPDIR from the listed locations.
File-descriptor utility API

Summary
Public lock API and XUtils import Sources/XUtils/System+Utils.swift, Sources/XKit/Utilities/KeyValueStorage.swift
FileDescriptor.LockMode and tryLock(mode:) become public. KeyValueStorage.swift adds an XUtils import.

Full details: Title check
Explanation
The title "utils: small tweaks" is vague and generic. It does not name the main change. The changeset adds a CommandVersion type that carries an uncommitted-changes flag, moves the xtool version to that type, adds XToolCache.directory as the temporary directory root, and makes LockMode and tryLock public. The title uses "small tweaks" and does not convey any of this, so a teammate scanning history cannot tell the primary change.
Resolution
Replace the title with a short description of the primary change. For example, name the version handling change or the temporary directory change, such as "Track uncommitted changes in xtool version" or "Use XDG-based cache directory for temporary directories."

The path that the NSURL object will represent. `path` should be a valid system path, and must not be an empty path. ... If `path` is a relative path, it is treated as being relative to the current working directory.
# init(fileURLWithPath:)
Initializes a newly created NSURL referencing the local file or directory at `path`.
`init(fileURLWithPath path: `String`)`
## Parameters
`path`
The path that the NSURL object will represent. `path` should be a valid system path, and must not be an empty path. If `path` begins with a tilde, it must first be expanded with `expandingTildeInPath`. If `path` is a relative path, it is treated as being relative to the current working directory.
## Return Value
An NSURL object initialized with `path`.
## Mentioned in
Improving performance and stability when accessing the file system
## Discussion
Invoking this method is equivalent to invoking `init(scheme:host:path:)` with scheme `NSURLFileScheme`, a `nil` host, and `path`.
This method assumes that `path` is a directory if it ends with a slash. If `path` does not end with a slash, the method examines the file system to determine if `path` is a file or a directory. If `path` exists in the file system and is a directory, the method appends a trailing slash. If `path` does not exist in the file system, the method assumes that it represents a file and does not append a trailing slash.
As an alternative, consider using `init(fileURLWithPath:isDirectory:)`, which allows you to explicitly specify whether the returned `NSURL` object represents a file or directory.</excerpt>

Instance Property
# URL
A URL object derived from the components object.
`@property (copy, readonly, nullable) `NSURL` * URL;`
## Discussion
If the receiver has an authority component (user, password, host, or port) and a path component, then the path must either begin with `"/"` or be an empty string. Otherwise, this property contains `nil`.
If the receiver does not have an authority component (user, password, host, or port) and has a path component, the path component must not start with `"//"`. If it does, this property contains `nil`.
If the receiver has `nil` values for all component properties, such as when initializing with `init`, this property returns an `NSURL` object with an empty string, because a URL always has a path—even if it’s an empty string.
This property can be used only to obtain a URL based on the values of the other properties. To configure a components object based on an existing URL, call either the `componentsWithURL:resolvingAgainstBaseURL:` or `initWithURL:resolvingAgainstBaseURL:` method.

### Structure of a URL
An `NSURL` object is composed of two parts—a potentially `nil` base URL and a string that is resolved relative to the base URL. An `NSURL` object is considered absolute if its string part is fully resolved without a base; all other URLs are considered relative.
For example, when constructing an `NSURL` object, you might specify `file:///path/to/user/` as the base URL and `folder/file.html` as the string part, as follows:
`NSURL *baseURL = [NSURL fileURLWithPath:@"file:///path/to/user/"];
NSURL *URL = [NSURL URLWithString:@"folder/file.html" relativeToURL:baseURL];
NSLog(@"absoluteURL = %@", [URL absoluteURL]);
`
When fully resolved, the absolute URL is `file:///path/to/user/folder/file.html`.
A URL can be also be divided into pieces based on its structure. For example, the URL `https://johnny:p4ssw0rd@www.example.com:443/script.ext;param=value?query=value#ref` contains the following URL components:
Component | Value
--- | ---
`scheme` | `https`

Initializer
# init(path:)
Returns an `NSBundle` object initialized to correspond to the specified directory.
`init?(path: `String`)`
## Parameters
`path`
The path to a directory. This must be a full pathname for a directory; if it contains any symbolic links, they must be resolvable.
## Return Value
An `NSBundle` object initialized to correspond to `fullPath`. This method initializes and returns a new instance only if there is no existing bundle associated with `fullPath`, otherwise it deallocates `self` and returns the existing object. If `fullPath` doesn’t exist or the user doesn’t have access to it, returns `nil`.
## Discussion
It’s not necessary to allocate and initialize an instance for the main bundle; use the `main` class method to get this instance. You can also use the `bundleWithPath:` class method to obtain a bundle identified by its directory path.

Treat an empty XTL_TMPDIR as unset.
An empty value reaches URL(fileURLWithPath:), whose contract requires a non-empty path. Use the default cache location for an empty override. Relative paths are valid Foundation inputs and are documented as relative to the current working directory, so do not reject them without changing the XTL_TMPDIR contract.
