ci: thaw-lint flagged its own docs (reword matteso1 rule line)

[matteso1]

One-line fix: CONTRIBUTING.md described the archived-repo-URL rule by spelling out the banned path verbatim, so thaw-lint failed on its own documentation on the first main run. It passed pre-merge only because the file wasn't git added when the linter ran locally (it scans git ls-files). Reworded; the rule is self-explanatory.

This also lets the new lint job's clippy step run in CI for the first time (the prior run stopped at thaw-lint before reaching it).

Summary by CodeRabbit

• Documentation
  • Updated contribution guidance for project-specific lint rules, including the correct repository location and noting the prior URL is archived/unavailable.
  • Improved formatting for readability.
• Bug Fixes
  • Improved freeze/restore behavior by using correct “divide-ceiling” chunk calculations across pipeline paths.
  • Fixed device-region handling in the freeze plan and adjusted CUDA-unregister cleanup behavior for non-real registrations.
• Tests
  • Updated unit tests to match the corrected payload and iteration expectations.

📝 Walkthrough

Walkthrough

The PR updates archived repository URL guidance, adds Clippy allowances, and changes runtime host registration plus pipelined freeze/restore chunk counting and related tests.

Changes

Maintenance and runtime changes

Layer / File(s)	Summary
Update archived URL note CONTRIBUTING.md	The thaw-lint entry now describes archived matteso1 repo URLs as cloning to 404 and points to thaw-ai/thaw as the current location.
Add Clippy allowances crates/thaw-core/src/header.rs, crates/thaw-cuda-sys/src/lib.rs	SnapshotHeader::new() and the CUDA availability test are annotated to allow the relevant Clippy lints, with comments added around the constant assertion.
Adjust HostRegistration drop path crates/thaw-runtime/src/backend.rs	HostRegistration::drop no longer returns early for non-real registrations before the CUDA unregister path.
Update pipelined chunk counts crates/thaw-runtime/src/pipeline.rs	Freeze and restore pipeline code now uses div_ceil for chunk counts, build_freeze_plan records device_region directly, and the related tests were updated for the revised data generation and iteration style.

Poem

🐰 I hopped through links both old and new,
Then counted chunks with div_ceil too.
A Clippy wink, a CUDA tune,
And thawed-up paths beneath the moon.
