* Add initial support for IPv6

* address comments (part 1)

* quick clean up of missed fix suggestion

* Fix misassigned default serving server address in adapter client

* add wrapper method to get host and port from`getsockname`

* Before this change it was not possible to attach to a process on arm64 mac.

The primary issue was that we weren't building the attach.dylib for all targets; but even once we did that we had to ensure that we were exiting successfully after injecting into the process.

We pulled in the compile changes from JetBrains/intellij-community@2e7109f

* Add parent-session-pid argument

Add the ability to specify the parent process id when connecting a new
DAP server to the client. This value is used instead of the actual
process' parent id so that it can be associated with a specific debug
session even if it hasn't been spawned directly by that parent process.

* Add tests for new option

* Fix debugger stepping actions in forked process

Fix the debugger stepping state when debugging a process that has been
forked from the main process. The new sys.monitoring mechanism didn't
fully clear the thread local storage after a fork leading to a state
where the forked child process tracked the wrong thread information and
was never updated on the latest continue action.

* Add stepping test for forked process

* Add line ending back in for cleaner diff

* More formatting reversions

* Expose CLI Options through public API

Expose a public API that can retrieve the processed CLI options for the
current process launched through the debugpy CLI. This enables code to
be able to retrieve options like the port and adapter access token to be
used for launching their own child process' that can be debugged.

* Fix test by sending dict not dataclass object

Follow-up to #1917, which changed the prefix for Windows. The crux of that contribution was about enabling attaching on Sillicon Mac (in fact, it came from my colleagues at Zed Industries). This however broke .dll lookup per zed-industries/zed#35640 (comment)

* check if os.file is available before using it

* use threading.__file__ als last fallback

* update testing for python 3.14

* Allow python 3.14 in attach code

* move 3.14 to its own job outside of matrix

* try 3.14.0-rc.2

* allowUnstable

* use 3.14.0-rc.2 but use 3.14 in tests
