Temporary fix of SwiftPM Bug using task.sh

SwiftPM has currently a bug, that products or targets of dependencies
are taken into consideration when resolving names, regardless if they're
used or not by the root package. This stops Swift PM from working on packages,
that declare this package as a dependency and define their own TaskCLI target,
as they collide with the definitions of this package. This is resolved, by
prefixing TaskCLI with the package name.
The product collision - which causes swift run - to run this package's task
executable is resolved, by adding that product only temporarily during task
execution using task.sh.

 Internally this listens for `CREATE` events carrying the ``InotifyEventMask/isDir`` flag and installs a new watch with the same mask whenever a subdirectory appears.
 
+### Excluding Directories
+
+When watching large trees you often want to skip certain subdirectories entirely — version-control metadata, build artefacts, dependency caches, and so on. Call ``Inotify/Inotify/exclude(names:)`` **before** adding a recursive or automatic-subtree watch:
+
+```swift
+let inotify = try Inotify()

+Excluded names are matched against the last path component of each directory during resolution and are also filtered from the event stream, so you never receive events for items whose name is on the exclusion list.

+# Usage:  task [arguments...]

+# The script auto-detects the package name from Package.swift and expects an
+# executable target named "<PackageName>TaskCLI" to exist.
