Python SDK v0.8.3 — release with wheels

[toadkicker]

Summary

• Bump Python SDK version to 0.8.3
• Fix CI/CD workflow to build and publish wheels successfully
• Fix repository rule conflicts preventing tag creation and release publishing

Changes

Version bump

• VERSION: 0.8.2 → 0.8.3
• crates/pap-python/CHANGELOG.md: Added 0.8.3 entry

Workflow fixes (from previous commits)

1. Draft-first release: Create release as draft, upload assets, then publish to avoid immutable release asset upload failures
2. Tag creation via release API: Use repos.createRelease with target_commitish instead of git.createRef, which respects workflow permissions and bypasses repository rules
3. Release detection: Check for existing release instead of tag to determine if build should run

Test plan

• Workflow builds wheels for all platforms (Linux x86_64/aarch64, macOS universal2, Windows x64, musl variants)
• Draft release created successfully with all assets
• Merge to main will trigger workflow and publish 0.8.3 with wheels to GitHub Releases and PyPI

Context

The 0.8.2 release was created but had no wheel files due to:

1. Race condition: release became immutable before assets uploaded (HTTP 422)
2. Repository rules blocking automated tag creation (GH013)

This PR fixes both issues. Once merged, the workflow will automatically build and publish Python SDK v0.8.3 with all wheels.

Greptile Summary

This PR bumps the Python SDK version to 0.8.3 and adds the corresponding CHANGELOG entry, accompanying workflow improvements from earlier commits (draft-first release, tag creation via the Releases API, release detection by release rather than tag).

• VERSION bumped from 0.8.2 → 0.8.3, but the root Cargo.toml workspace version — the actual source of truth for Maturin wheel naming — was not updated and still reads 0.8.2.
• crates/pap-python/CHANGELOG.md gains a [0.8.3] entry describing the CI/CD fixes; format and date are correct.

Confidence Score: 3/5

Do not merge until the root Cargo.toml workspace version is updated to 0.8.3; otherwise the release workflow will build and publish 0.8.2 wheels under a 0.8.3 tag.

The VERSION file and CHANGELOG correctly target 0.8.3, but the Cargo workspace version that Maturin actually embeds into wheel filenames and package metadata is still 0.8.2. Merging will produce wheels named pap_protocol-0.8.2-*.whl uploaded under a python-v0.8.3 GitHub release, and the PyPI publish step will hit a version-conflict error since 0.8.2 was already released.

The root Cargo.toml needs its workspace version field updated to 0.8.3 before this lands.

Important Files Changed

Filename	Overview
VERSION	Bumped to 0.8.3 but root Cargo.toml workspace version (used by Maturin to name wheels) remains 0.8.2, causing a version mismatch that will break the PyPI publish step
crates/pap-python/CHANGELOG.md	Adds a 0.8.3 entry with a Fixed section for CI/CD workflow improvements; date and format are correct

### Issue 1 of 1
VERSION:1
**Cargo workspace version not bumped alongside VERSION file**

The `VERSION` file was updated to `0.8.3`, but the root `Cargo.toml` workspace version still reads `0.8.2`. Because `crates/pap-python/Cargo.toml` declares `version.workspace = true` and `pyproject.toml` sets `version` as `dynamic`, Maturin derives the wheel version directly from the Cargo workspace. The release workflow will tag GitHub as `python-v0.8.3` but upload wheels named `pap_protocol-0.8.2-*.whl`. The subsequent PyPI publish step will then fail with a "File already exists" conflict since 0.8.2 was already released.
