docs: Add Tagalog README Translation

[harveyjavier]

Relates to:

#1419

Risks

Low - This is a documentation-only change adding a new translation file.

Background

Adds Tagalog translation of the main README.md file as README_TG.md, including:

• Full translation of all main sections
• Proper Tagalog character rendering and formatting
• Maintained all links and functionality from the original README

What kind of change is this?

Improvements (adds new language support to existing documentation)

Documentation changes needed?

My changes are documentation changes themselves - adding a new translated README file.

Testing

Where should a reviewer start?

• Open README_TG.md in either VSCode/Cursor/github.dev's Markdown preview
• Verify formatting is correct
• Check that all links are functional
• Verify Tagalog text renders properly

Detailed testing steps

• View the raw file to verify proper Tagalog text formatting
• View the rendered file to ensure readability and consistency
• Check that the language selector at the top includes a Tagalog link
• Verify all internal links work correctly
• Ensure images and formatting match the main README.md structure
