octoturge bc4ee8690a Drop proto/bambulab/ — plain hand-written Rust structs instead
Reconsidered after actually feeling the friction: this data is JSON over
MQTT (not binary protobuf), only continuum-proxy ever parses it (raw
vendor wire format, never crosses into TS), so none of protobuf's actual
value (cross-language codegen, binary wire efficiency) applied here.
Every gotcha hit while building this (field_attribute's oneof/variant
path collision, needing .bambulab-scoped type_attribute calls, explicit
#[serde(default)] per not-always-present field) came from forcing
prost-build's codegen model onto a plain-JSON, Rust-only use case.

Verified the replacement is strictly simpler, not just smaller: a
hand-written struct's Option<T> field needs zero extra attributes to
handle a missing JSON key (prost's generated String needed an explicit
field_attribute call per field), and #[serde(flatten)] on a hand-written
field has no ambiguity at all (prost-build's oneof/variant path collision
doesn't exist without prost-build's codegen in the picture).

The replacement lives in continuum-proxy: src/printer/bambu_commands/.
continuum.v1 is unaffected — that schema is genuinely cross-language and
proto still earns its keep there.
