chore: update shared ruff pin

[stranske]

Summary

• update the canonical shared Ruff pin to 0.15.20
• sync the matching pyproject, requirements.lock, consumer template, and integration template pins

Validation

• python3 scripts/sync_tool_versions.py --check
• python3 scripts/validate_version_pins.py --check-all-templates
• python3 scripts/validate_template_sync.py
• python3 scripts/validate_template_completeness.py
• git diff --check
• /opt/anaconda3/bin/python3.12 -m pytest tests/scripts/test_sync_tool_versions.py tests/scripts/test_validate_version_pins.py

Campaign Context

Supersedes integration-only Renovate PR stranske/Workflows-Integration-Tests#40, which only bumped pyproject.toml and caused reusable CI to install conflicting Ruff pins.

Summary by CodeRabbit

• Chores
  • Updated the pinned Ruff version to 0.15.20 across development and workflow configuration.
  • Aligned template repository settings with the latest Ruff release for consistent formatting and linting behavior.

Workflow source needed

PR #2537 needs either a linked GitHub issue or one valid non-issue Workflow Source before PR metadata automation can manage it safely.

Please do one of:

• Add <!-- meta:issue:123 --> or a normal Closes #123 / Related to #123 line.
• Check one Workflow Source option in the PR body.
• Add a hidden marker such as <!-- workflow-source:local_request -->, <!-- workflow-source:manual_remote -->, <!-- workflow-source:review_followup -->, <!-- workflow-source:sync_campaign -->, or <!-- workflow-source:dependabot -->.
• Add a workflow source label such as workflow:source-direct-pr, workflow:source-local-request, workflow:source-review-followup, workflow:source-sync, or workflow:no-automation.

Once a valid source is present, this warning will not be reposted.
