Replace custom workflows with reusable Quality and Release workflows

[gesslar]

This pull request replaces the existing GitHub Actions workflows with a streamlined CI/CD setup using reusable workflows from the gesslar/Maint repository.

Added workflows:

• Quality workflow: Runs on push, pull requests, manual dispatch, and weekly schedule (Mondays at 14:20). Performs automated linting and testing based on repository variables, with auto-detection of package manager.
• Release workflow: Triggers on closed pull requests to main branch, handles automated releases with quality checks and content write permissions.

Removed workflows:

• Auto PR and merge workflow for dev branch
• CodeQL security analysis workflow
• Auto-rebase workflow for pull requests

The new setup centralizes maintenance tasks through external reusable workflows while maintaining automated quality checks and release management.
