Investigate packaging endcord 1.3.0

[chenrui333]

Source-build packaging for endcord 1.3.0 is currently blocked.

Evidence collected locally on macOS:

1. brew update-python-resources /tmp/endcord-formula-lab/Formula/e/endcord.rb failed because pip could not determine dependencies for the upstream source tarball.
2. Reproducing the exact pip dry-run showed upstream metadata/build discovery fails immediately:

ModuleNotFoundError: No module named 'Cython'
ERROR: Failed to build 'https://github.com/sparklost/endcord/archive/refs/tags/1.3.0.tar.gz' when getting requirements to build wheel

Command used:

/opt/homebrew/opt/python@3.13/libexec/bin/python -m pip install -v --disable-pip-version-check --dry-run --ignore-installed --report=/dev/stdout https://github.com/sparklost/endcord/archive/refs/tags/1.3.0.tar.gz

3. A follow-up attempt with Cython preinstalled and --no-build-isolation got past the first failure but still showed the project is using nonstandard packaging metadata/workflows that need manual formula workarounds rather than the normal Homebrew Python resource flow.

What this means for the formula:

• normal virtualenv_install_with_resources generation is blocked
• upstream source metadata likely needs a formula-side patch or upstream fix so Cython is declared correctly for source builds
• the CLI also appears to require a manual wrapper around main.py, since upstream is not exposing a standard console script entry point in pyproject.toml

Decision needed:

• either patch the formula around the broken metadata/manual wrapper path
• or wait for an upstream packaging fix before adding endcord
