Prepare component licensing for EgoPost

[jiwenc-nv]

Prepare Isaac Capture to host EgoPost under OpenMDW-1.1 while preserving root LICENSE.md verbatim as Apache-2.0.

Adds a license-only src/python/isaaccapture_egopost/ directory, canonical license text, scoped REUSE defaults, and concise contribution guidance. Pre-commit checks source files repository-wide and all EgoPost assets, adds default NVIDIA headers to unannotated first-party files, and repairs default EgoPost license tags while preserving explicit exceptions.

Both packaging paths include the root Apache license. Package discovery and source-archive exclusions keep EgoPost out of Isaac Capture distributions until its integration is explicitly implemented.

Validation: full pre-commit passed; 12 licensing regression cases passed; source archive built and inspected; scikit-build metadata checked; setuptools wheel built from Python-only staging and its license/exclusion check passed. Full native builds remain for CI. Whole-repository REUSE still has legacy gaps and reports the reserved OpenMDW text unused until source files are imported.

Summary by CodeRabbit

• Documentation

  • Clarified that Apache-2.0 is the default project license, while EgoPost uses OpenMDW-1.1 and third-party materials may have separate terms.
  • Added licensing guidance for contributions, including how license headers are handled.

• Packaging

  • Project license information is included in Python package metadata and distributions.
  • EgoPost is not included in the source distribution or wheel.

• Chores

  • License checks now run automatically during pre-commit and can add or update headers.

📝 Walkthrough

The changes define Apache-2.0 as the default license and OpenMDW-1.1 for EgoPost. A new script checks and optionally repairs license annotations, and pre-commit runs it with --fix. Python packaging metadata and contents are updated to declare and include the root license while excluding EgoPost from the source distribution. New tests cover license policy, repair behavior, and wheel contents.

Merge Risk: 🟡 Moderate · up to f8645

The current license assignment is correct, but the checker would not catch a future incorrect EgoPost default. Fix that safeguard before relying on it for imported source files.

- Around line 45-48: Update explicit_exception in the license-checking flow to
distinguish sidecar or file-level SPDX declarations from licenses supplied by
REUSE’s subtree closest annotation; do not treat the EgoPost default as an
exception. Validate the EgoPost default’s license identifier so changing it to
Apache-2.0 fails policy checks even for copyright-only headers.
