Internalize the route scope behind InheritableSetting accessors

Every raw `route[...]` poke from outside InheritableSetting is replaced by
a semantic accessor, so nothing external touches the `@route` hash anymore
(the `route` reader is now reachable only from specs and can go internal
later):

* `route_validations` / `route_declared_params` (+ writers) — the flat
  per-route param snapshots seeded per endpoint and topped up on mount.
* `route_renamed_params` / `add_route_renamed_param` — the `as:` rename
  map, an accumulator replacing the read-modify-write in ParamsScope.
* `route_description` (+ writer) — the `desc` block's settings.
* `route_settings` — the settings handed to each Route (everything but the
  internal snapshots), replacing the `route.except(...)` in Endpoint.
* `route_setting` — the open store behind the `route_setting` DSL, which
  now delegates here instead of reaching into the raw hash.
* `inherit_route_params` — folds a mounting parent's namespace snapshots
  into the route buffers, replacing the merge that lived in
  `Endpoint#inherit_settings`.

Bumps Metrics/ClassLength to 370; the class is a settings registry and
will shrink again once its stores are extracted.
