Adds the shared tts-client.js player (Hitokoto CPU TTS) to the Reader. reader-speech.mjs supplies a growing-text adapter per format: TXT/Markdown/HTML rendered text, Foliate EPUB/MOBI/FB2 sections, chapter bundles, native PDF text layers and pdf-pages/v3 OCR text layers. Highlights use the CSS Custom Highlight API in the owning realm; DOM text is never modified. Images/media/pages without text get no button. CSP adds the Hitokoto origin to connect-src and Hitokoto plus blob: to media-src. Inventory, components and release gate list the new files on both sites.
