fix(embedded): enable abi3-py311 for cross-version wheel compatibility

[polaz]

Summary

• coordinode-embedded was publishing only cp311 wheels for Linux (CI runner has Python 3.11)
• Google Colab runs Python 3.12 — pip cannot find a compatible wheel → installation fails
• Fix: add abi3-py311 feature to pyo3, producing a single cp311-abi3 wheel per platform
• The cp311-abi3 wheel is compatible with Python 3.11, 3.12, 3.13, 3.14+ automatically

Change

One line in coordinode-embedded/Cargo.toml:

pyo3 = { version = "0.23", features = ["extension-module", "abi3-py311"] }

maturin detects abi3-py311 and sets the wheel tag accordingly. No CI matrix changes needed.

Verified locally

📦 Built wheel for abi3 Python ≥ 3.11 to coordinode_embedded-0.1.0-cp311-abi3-macosx_11_0_arm64.whl

Installed successfully on Python 3.12 (uv run python = 3.12.11).

Closes #65

Walkthrough

The PR enables the abi3-py311 feature flag for the pyo3 dependency in coordinode-embedded/Cargo.toml. This configures the build system to produce stable ABI-compatible wheels that work across Python 3.11 and later versions, addressing installation failures on Python 3.12+ environments like Google Colab.
