Phase 1.3: CI/CD Modernization (#1791)

* create new feature branch; add audit file

* ci: fix FlatBuffers paths for src/ layout

Update paths in FlatBuffers Schema Build job from autobahn/wamp/gen/
to src/autobahn/wamp/gen/ to match the modernized src/ directory
structure.

* ci: migrate from mypy to ty type checker

- Remove mypy from dev dependencies in pyproject.toml
- Update justfile check-typing recipe to use ty
- Update distclean to remove .ty/ instead of .mypy_cache/
- Install ty in main.yml via uv tool install
- Enable type checking step in CI (was disabled for mypy)
- Add py.typed marker file for PEP 561 compliance
- Remove continue-on-error from test steps

ty is Astral's Rust-based type checker which:
- Runs on PyPy (unlike mypy which requires librt/mypyc)
- Is significantly faster than mypy
- Provides cleaner error output

* ci: fix ty check-typing configuration

- Only check src/autobahn/, exclude src/flatbuffers/ (generated code)
- Add all necessary --ignore flags for existing type errors
- Add FIXME comments noting type errors need follow-up work

The type checker now passes but with many rules ignored.
A follow-up issue should be created to fix the actual type
annotations in the codebase.

* build: add auditwheel repair to convert wheels to manylinux format

- Run auditwheel repair after building wheel to convert linux_x86_64
  to manylinux format, matching the CI/CD workflow output
- Remove original linux wheel after successful manylinux conversion

This ensures local builds match GitHub Actions wheel output.

Note: This work was completed with AI assistance (Claude Code).
