Move markdown-unlit to build-tools (#98)

* Move markdown-unlit from dependencies to build-tools

This avoids unused-package warnings and removes the need for empty imports.

🤖 Generated with Claude Code

* fix yaml crap

* Update nightly resolver to current version

Change from nightly-2023-07-25 to nightly to use the
current nightly snapshot.

* Fix deprecated System.Random.split usage

Replace deprecated 'split' function with 'splitGen' for compatibility
with newer random library versions in nightly snapshots

* Revert to using System.Random.split with deprecation warning suppression

The split function is deprecated but will remain available for backward
compatibility. Using splitGen breaks older Stack resolvers that don't
have the SplitGen type class. Added pragma to suppress deprecation warning.

* Use concrete nightly snapshot date

Specify nightly-2025-09-23 instead of just 'nightly' for reproducible builds.
