Gate generated code behind feature flags so consumers can build in no_std/no_alloc environments: - Runtime: gate RotoMessage, RotoOwned, BufMutBuilder behind alloc - Codegen: split DATA_IMPORTS, gate Owned* structs + service code - Fix RevBuilder::with() to iterate forward without Vec allocation - Wire up bytes/std via alloc feature (Bytes requires Arc) - Update consumer Cargo.toml files with proper feature chains - Add no_std_test example for embedded validation

Update codegen to make `bytes` imports conditional on the `alloc` feature and add a test example for the `thumbv7em-none-eabihf` target.
Add #![no_std] to the runtime crate and introduce optional std and alloc features. Update the code generator to be compatible and add a no_std_test example. Remove the generator binary.
