[ci] chore: automate PR labeling and integrate Codecov coverage reporting

[JoyboyBrian]

What

• Add .github/workflows/auto-label-pr.yml to auto-apply labels from PR titles ([module] type: ...), including [BREAKING], type-based labels, and module label mapping.
• Update .github/workflows/tests.yml to generate branch coverage and coverage.xml on Python 3.12, then upload coverage to Codecov via codecov/codecov-action@v5.
• Add codecov.yml with project/patch coverage targets (70%) and diff-focused comments.
• Clean up unused code and imports across rollout/auth/example modules, including unused logger declarations and dead assignments.
• Simplify task awaiting in EvalRunner by removing unused tuple unpacking (await task).
• Update README signup URL to https://platform.osmosis.ai and refresh uv.lock dependency patches (aiohttp 3.13.2 -> 3.13.3, urllib3 2.6.2 -> 2.6.3).

Why

• Reduce manual PR triage and keep labels aligned with release-note categories through title-driven automation.
• Make CI coverage outputs consumable by Codecov and establish a baseline quality gate for project and patch coverage.
• Remove dead code to reduce maintenance noise and keep lint/static analysis clean.
• Apply dependency patch updates from Dependabot-related maintenance and keep docs links accurate.

Type of Change

• Bug fix (non-breaking change that fixes an issue)
• New feature (non-breaking change that adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)
• Refactor (code change that neither fixes a bug nor adds a feature)
• Documentation update
• CI/build configuration change

How to Test

1. Run uv run pytest --cov=osmosis_ai --cov-branch --cov-report=term-missing --cov-report=xml.
2. Confirm coverage.xml is generated in the repo root.
3. Verify the Codecov upload step is triggered for Python 3.12 in GitHub Actions.
4. Open or edit a PR title in [module] type: description format and verify labels are auto-applied.
5. Run ruff check . and ruff format --check ..

Checklist

• PR title follows [module] type: description format
• Appropriate labels added (e.g. enhancement, bug, breaking)
• ruff check . and ruff format --check . pass
• pyright osmosis_ai/ passes
• pytest passes (new tests added if applicable)
• Public API changes are documented (N/A: no public API changes)
• No secrets or credentials included

Summary by cubic

Automates PR labeling from titles, integrates Codecov coverage reporting with guarded uploads for non-fork PRs, and removes dead code to reduce noise. Also updates the README signup link and patches dependencies.

• New Features

  • Added auto-label workflow parsing “[module] type: …” titles, including “[BREAKING]” and type→label mapping.
  • CI: Added branch coverage and XML output; upload coverage to Codecov on Python 3.12 only for non-fork PRs; included codecov.yml with 70% project/patch targets and diff-focused comments.

• Refactors

  • Removed unused loggers and dead code across auth, rollout (eval/test CLI, server, tools, validator), and examples; simplified EvalRunner awaiting; dropped CredentialsStore.get_workspace_names.
  • Updated README signup URL to platform.osmosis.ai and refreshed uv.lock (aiohttp 3.13.3, urllib3 2.6.3).
