Drop Protobuf; move continuum/v1 domain model to JSON Schema

Nothing imported the proto-generated code (zero references to continuum-rust-types or @continuum/ts-types's proto export in any consumer repo), and protobuf's real value - one schema compiled to a compact binary wire format for both languages - never applied: BE<->proxy and FE<->BE are both JSON. Also fixes 8 broken $ref paths in the bambulab schemas and a root tsconfig.json that was sweeping the gitignored examples/ directory into typecheck. - proto/continuum/v1/*.proto -> schemas/continuum/v1/*.schema.json - packages/rust-types: hand-written serde structs instead of prost-build codegen - packages/ts-types: drop the generated/ proto barrel export, keep the hand-written TypeBox schemas as the TS source of truth - root package.json: drop build:ts, protoc, ts-proto

-// Bambu's raw MQTT command/report structs are NOT modeled here - they're
-// plain hand-written Rust + serde in continuum-proxy's
-// src/printer/bambu_commands/, not proto. That data is JSON-over-MQTT
-// (not binary protobuf), and only continuum-proxy ever needs to parse it
-// - none of protobuf's actual value (cross-language codegen, binary wire
-// efficiency) applies, and forcing it through prost-build's codegen model
-// anyway produced real, avoidable friction (see this crate's git history
-// for the specifics: a field/variant attribute-matching collision on
-// `oneof`, needing package-scoped `type_attribute` calls, explicit
-// `field_attribute(..., "#[serde(default)]")` for fields that aren't
-// always present - every one of these disappears with a hand-written
-// struct, where `Option<T>` and `#[serde(flatten)]` just work with zero
-// configuration). Proto stays for continuum.v1 above, which - unlike
-// this - is a schema we designed ourselves and that both TS and Rust
-// genuinely need.
