feat(facts): phase 13 - per-game facts, Rust and RunicNPC checked, main green again

platform.json drops the single protocol/bundle/capability list for a
`games` object (uo, rust) plus a `runicnpc` block. checkFacts.mjs loops
the protocol, plugin-protocol, capability and bundle checks over both
games, reads the schema-2 bundles at v2/<game>/current.json, checks each
module's coreApi, and reads RunicNPC's plugin.toml. 41 facts, up from 19;
clears the two that were red on main (Module API 1.17.0, installer
v0.8.0).

D66: the hero, footer and structured data show the Module API only; each
game's protocol and bundle go on that game's pages, and the docs landing
table splits into shared versions plus one column per game.

The re-read section 1 requires found, and this fixes:
- three hard-coded "1.6.0" Module API versions in the module docs
- module-lifecycle saying modules load alphabetically (the loader now
  refuses a second module, W19), and the install pages never mentioning
  the one-module rule
- "there is one module" in five places, now two modules both built
  inside this project; the Integration Kit keeps its draft banner
- the homepage diagram's ServUO/uo-link sub-labels (D63 wording now)

notBuilt drops `second-module` (resolved by Module-Rust's release) and
rewords `multi-module`.
