ensure nightly builds always produce new packages, expand 'changed-files' lists

[jameslamb]

Contributes to rapidsai/build-planning#218

• uses the new patterns for versioning nightly packages (see builds: add support for computing a date-based version component at build time shared-workflows#603), to ensure they're always uploaded on new builds.

For wheels:

# before
26.10.0a55 

# after
26.10.0a55.post260803200854

And for conda:

# before
26.10.0a55[build=cuda12_260803_9da146ef]

# after
26.10.0a55[build=cuda12_260803200854_9da146ef]

Other changes:

• updates changed-files lists to avoid triggering test jobs in PR CI when only .github/workflows/{build,test}.yaml are changed

📝 Walkthrough

Summary by CodeRabbit

• Build and Release Improvements
  • Improved build workflows with consistent build timestamp information across compiled libraries, Python packages, and wheels.
  • Updated package version metadata to include precise build date and time details.
  • Improved pull request change detection for workflow and configuration updates.
• Packaging
  • Updated Conda package build identifiers for more precise release metadata.
  • Refined build sequencing to ensure required build information is available before packaging.

Walkthrough

Build workflows now compute and propagate a shared build datetime. Build scripts and Conda recipes use datetime-based metadata. PR file filters exclude additional GitHub configuration and workflow files.

Changes

Build datetime integration

Layer / File(s)	Summary
Workflow build metadata propagation .github/workflows/build.yaml, .github/workflows/pr.yaml	Adds reusable build-details jobs, passes build-datetime to build jobs, updates job dependencies, and expands PR file exclusions.
Build script datetime inputs ci/build_cpp.sh, ci/build_python.sh, ci/build_wheel.sh	Replaces rapids-date-string with rapids-datetime-string. Wheel builds add the datetime to the VERSION suffix.
Conda package build metadata conda/recipes/libnvforest/recipe.yaml, conda/recipes/nvforest/recipe.yaml	Uses RAPIDS_DATETIME_STRING for package build strings.
