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

  • Added automated build-detail generation across standard and pull-request build workflows.
  • Improved version identification by including precise date-and-time information in development build suffixes.
  • Ensured C++ and Python packages and wheels use consistent timestamp details.
  • Updated package metadata to reflect the enhanced timestamp format.

• Maintenance

  • Refreshed copyright information across build and packaging configuration.
  • Improved build workflow consistency and configuration accuracy.

Walkthrough

The workflows now compute shared build timestamps and pass them to build jobs. Build scripts and Conda recipes use datetime-based metadata, including timestamped wheel versions.

Changes

Build metadata

Layer / File(s)	Summary
Reusable build-detail workflow wiring .github/workflows/build.yaml, .github/workflows/pr.yaml	Both workflows add the shared compute-build-details.yaml workflow, pass its build-datetime output to build jobs, and update path exclusions.
Datetime-based build and package metadata ci/build_*.sh, conda/recipes/*/recipe.yaml	Build scripts and Conda recipes replace date strings with datetime strings. Wheel builds add timestamp-based .post version suffixes. Copyright notices are updated through 2026.

build-details job via needs and pass its build-datetime output as the reusable
