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 rapidsai/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

  • Added consistent date-and-time metadata to C++, Python, and wheel builds.
  • Package build identifiers now include precise build timestamps, improving release traceability.
  • Coordinated shared build information across dependent automated workflows.

• Maintenance

  • Updated build scripts and package recipes to use the standardized timestamp format.
  • Refreshed copyright information in relevant build files.
  • Improved pull request workflow handling for documentation and test-only changes.

Walkthrough

The workflows add a shared build-details job and propagate build-datetime to build jobs. Shell scripts and conda recipes replace date-only metadata with datetime-based values.

Changes

Build datetime propagation

Layer / File(s)	Summary
Shared build metadata wiring .github/workflows/build.yaml	Adds the reusable build-details job and passes its build-datetime output to C++, Python, and wheel builds.
Pull request workflow integration .github/workflows/pr.yaml	Adds build metadata dependencies and outputs to pull request builds. Updates changed-file exclusions for build, labeler, and test workflows.
Datetime-based package metadata ci/build_*.sh, conda/recipes/*/recipe.yaml	Uses RAPIDS_DATETIME_STRING for build scripts and conda package build strings. Wheel versions receive a datetime-based .post suffix.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Haven't yet been able to get passing CI here. The most recent failure in Python tests (cond and wheels) looks like this:

FAILED test_sklearn_compatibility.py::test_sklearn_compatible_estimator[RandomForestRegressor()-check_regressor_data_not_an_array] - [XPASS(strict)] Predictions from repeated fits on equivalent inputs can differ beyond the check's tolerance

(build link)

Looks like #8458 skipped that test, pulling in latest main and trying another run.

[jameslamb]

CI is still stuck here because of the GitHub outage (https://www.githubstatus.com/incidents/qcvjkzcs7j74). Will try again later.

[jameslamb]

Wow looks like GitHub allowed a job that was queued over 6 hours ago to eventually get scheduled when they recovered from the outage... I thought for SURE they'd shed old jobs.

Anyway yay, this is merged 😁
