Guides: drop research and session language, move design history aside

- Remove "from research", "Round 3", "brief" and "this session" wording
  from the public guides; ai-assets gets a last-reviewed date
- provenance.md no longer quotes stale per-publisher counts, and states
  what publisher does today (named on entry pages, checked for
  consistency, not grouped); CONTRIBUTING says the same
- Delete docs/research-index.md and the CONTRIBUTING section about the
  gitignored RESEARCH/ folder
- Move docs/design/ and docs/superpowers/ under docs/internal/ with a
  README saying they are design history
- Take the review rubric out of the homepage Guides list
- godot-budget-stack: Gaea is non-commercial per its EULA, not
  needs-review

Closes #146

 - `commercial`: `true` / `false` / `unknown` / `varies`. Use `varies` for aggregators where some files are commercial-ok and others are not. The site still shows these under Commercial OK, labeled **per-file review**, so they are not silently excluded and not silently treated as a blanket grant.
 - `attribution_required`: `true` / `false` / `unknown`. If the licence normally requires credit (CC-BY) but the publisher waives it, set `false` and add a `- Attribution waived:` line in Notes saying so.
 - `attribution_string`: the copy-paste credit line. Required when `attribution_required` is `true`; optional otherwise.
-- `publisher`: optional. Name the **rights-holding publisher**, never the host. Set it whenever that publisher has more than one catalog entry, so the entries group; setting it on a publisher that currently has only one entry is also fine and saves a backfill later. Do not set it to a generic host or distributor (GitHub, Hugging Face, itch.io, OpenGameArt, the Internet Archive, Google Fonts) or to a distributor that does not hold the rights. Distinguish sibling organisations that are genuinely different rights holders: `blender.md` (the application, Blender Foundation) carries no `publisher`, while the asset bundles under `studio.blender.org` carry `Blender Studio`. Kenney, Quaternius, KayKit, LuizMelo, 0x72, Blender Studio, Material Maker, Alif Type, GGBotNet and 3dmodelscc0 are the largest groups in use today; treat that as illustrative, not as the permitted set.
+- `publisher`: optional. Name the **rights-holding publisher**, never the host. Set it whenever that publisher has more than one catalog entry, so each entry page names the same publisher and the validator can check that the group agrees; setting it on a publisher that currently has only one entry is also fine and saves a backfill later.

 - `subcategories`: lower-case kebab-case (`base-meshes`, `field-recordings`). Reuse a value already in the catalog before inventing one, and do not add a variant of an existing value that differs only in plural or spelling. Where both forms were in use, the more common one was kept (`characters`, `environment`, `interior`, `tileset`, `vectors`, `pixel`, `impulse-responses`, `base-meshes`). Retired spellings are listed in [`site/value-aliases.json`](site/value-aliases.json), which the validator enforces (V19); add a line there when you merge two values.
 - `formats`: what you actually get, in one of four kinds. **File formats**, as commonly written: usually upper case (`PNG`, `FBX`, `JSON`, `VOX`), tool-specific ones as the tool writes them (`gdshader`, `tmx`, `ktx2`). **Engine or language targets**, as the product writes them (`glTF`, `Godot`, `Unity`, `Python`, `React`). **Delivery types** for software with no file format of its own, lower-case kebab-case (`godot-addon`, `blender-extension`, `npm`, `cli`, `library`, `desktop-app`, `mobile-app`, `middleware`, `model`). And `various` for an aggregator whose files come in too many formats to list. Platforms (`windows`, `macos`, `ios`) and descriptions (`heightfield`, `examples`) are `tags`, not formats. The allowed values are the closed list in [`site/format-vocabulary.json`](site/format-vocabulary.json), which the validator enforces (V20): reuse a listed spelling, and add a genuinely new format there in the same change that first uses it. Its `groups` drive the site's Format filter, so a new format that belongs to a group (another glTF or font container) goes into that group too. A format outside every group is still searchable and shown on the card, but the Format filter cannot select it.
 - `tags`: lower-case kebab-case words describing the content (`low-poly`, `modular`, `platformer`). Do not restate another field: the licence (`cc0`, `mit`, `ofl`, `open-source`, `royalty-free`), the credit requirement (`no-attribution`) or the entry's own `publisher` (`kenney`) are rejected (V19 via `site/value-aliases.json`, V21), because search and the filters read those fields directly and a copied tag drifts. A `varies` entry lists its licence mix in the body, not in tags.

 By opening a pull request you dedicate your contribution to the public domain under [CC0 1.0](LICENSE), like the rest of the repository's metadata and documentation. Quotes from licence pages stay the publisher's words; they are used as short factual quotations, and the assets they describe keep their own licences.

 4. **Exclude free-tier cloud TTS/voice** that is non-commercial (ElevenLabs-class) from “commercial OK” lists.
 5. **Prefer local permissive models** (Apache 2.0 / MIT) when synthetic VO is needed.
