docs: add PineScript links to all indicator .md files, docsify .pine renderer with comprehensive Prism v6 syntax highlighting

- Added PineScript row to property tables in 375 .md files linking to companion .pine files
- Docsify plugin intercepts .pine link clicks, fetches and renders content as syntax-highlighted code blocks
- Comprehensive Prism.languages.pine grammar covering 18 token categories: annotations, types, qualifiers, namespaces, OHLCV builtins, functions, keywords, operators
- Custom CSS tokens using GitHub dark palette for Pine-specific visual differentiation

 - The FFT indicator computes the dominant cycle period in a price series using a radix-2 Cooley-Tukey Fast Fourier Transform with a Hanning window.
 - Parameterized by `windowSize` (default 64), `minPeriod` (default 4), `maxPeriod` (default 32).
