fix(templates): resolve all lint errors and warnings in bundled templates (#197)

## What

Added GSAP CDN imports to all template compositions and improved project linting to skip template placeholders.

## Why

Templates were missing GSAP script imports, causing JavaScript errors when GSAP animations tried to execute. The linter was also incorrectly flagging template placeholder values like `__VIDEO_SRC__` as missing audio sources.

## How

- Added `<script src="https://cdn.jsdelivr.net/npm/gsap@3.14.2/dist/gsap.min.js"></script>` to all composition HTML files
- Updated `lintAudioSrcNotFound` function to skip template placeholders matching the pattern `__[A-Z_]+__`
- Fixed GSAP animation properties by adding `overwrite: "auto"` to prevent conflicts
- Replaced CSS transforms with GSAP `gsap.set()` calls for better animation control
- Moved video elements outside timed containers in some templates to avoid nesting issues
- Standardized transcript data format to use double quotes for JSON consistency
- Added proper timeline initialization with `window.__timelines = window.__timelines || {}`
- Enhanced caption styling with overflow handling and max-width constraints

## Test plan

- [x] Manual testing performed
- [x] Verified GSAP animations work correctly in all templates
- [x] Confirmed linter no longer flags template placeholders as errors
- [x] Tested video playback and audio synchronization
