refactor(claude-desktop): replace [1M] suffix with supports1m field

inferenceModels entries now emit {name, supports1m: true} objects when
1M is enabled (plain strings otherwise), instead of appending a " [1M]"
suffix to model IDs. Route IDs and upstream model IDs are stored
verbatim; the suffix is rejected on input rather than silently stripped,
and proxy request mapping now requires an exact route_id match.
