- docs/tools/tts.md: alphabetize providers in three places that listed
them: the supported-providers table (Azure Speech ... Xiaomi MiMo),
the configuration Tabs (12 provider presets in A-Z), and the field
reference AccordionGroup. Top-level fields stay first; provider
tabs/accordions follow strict alphabetical order. Wording, schema,
and defaults unchanged.
- docs/docs.json: add tools/tts to the main Tools sidebar group
(slotted between trajectory and video-generation, matching the
alphabetical neighborhood with image-generation, music-generation,
video-generation). Previously tts only appeared under
Nodes > Media capabilities, which was a discoverability gap for
readers looking for TTS alongside the other generation tools.
