The last forge content in config.rs was vocabulary, not data:
`ForgeKind` (name/parse/token_env/default_base) and the pure
`resolve_token` helper. By the same rule that moved `Watch` to the
watch table and left `CalendarWatch` in the calendar integration,
the kind belongs to the crate that speaks the forges.
- `rhema-forge-integration` gains `kind::ForgeKind` and
`resolve_token`, with the parse and token-fallback tests moved
alongside — the claw's config tests were testing the integration's
type through a re-export.
- The claw's surfaces import the type from the integration directly;
the crate root re-exports it, so `rhema_claw::ForgeKind` keeps
resolving for everything downstream.
config.rs is now config: credentials, the surface, paths, cadence,
and nothing that knows what a forge or a calendar is.
