Feature/GitHub flows and files

[capachow]

• Fixed Documentation Links: Updated outdated MEDIA76 namespace URLs in README.md to correctly point to capachow.
• Modernized .github Structure: Renamed all uppercase files and folders (FUNDING.yml, ISSUE_TEMPLATE) to lowercase to meet modern repository standards.
• Enhanced Issue Templates: Added clean, minimalistic prompts to bug_report.md and feature_request.md to guide users without overwhelming them.
• Added PR Template: Created a pull_request_template.md to remind contributors to target the develop branch instead of master.
• Automated Releases (release.yml): Created a GitHub Action that automatically extracts the framework version from index.php, tags it with a standard v
  prefix, generates release notes, and attaches index.php as a direct download asset whenever develop is merged into master.
• Automated Syntax Linter (linter.yml): Added a lightweight GitHub Action that runs php -l index.php on all PRs targeting develop, ensuring fatal syntax errors are caught before code can be merged.
• Fixed Git Tracking: Updated .gitignore to explicitly un-ignore .github/ and its contents so templates and workflows are properly tracked.
• Standardized Formatting: Ensured POSIX-compliant trailing newlines across all markdown and YAML configuration files.
