Add RobStride RS00 and RS06 Rust codec and Python bindings

[ammarjmahmood]

DimOS has a Rust CAN control library for Damiao motors, but the existing Robostride motor type has no codec. This adds a separate no_std RS00 and RS06 codec plus Python bindings, allowing B601 RS motors to use the existing native transport and group APIs.

The codec implements MIT commands, explicit lifecycle frames, mode readback, typed parameter frame helpers, status and fault decoding. Motor identity binding provides model scaling and logical receive routing when motors share a host address. The core retains no vendor runtime dependency, and existing Damiao behavior is preserved. Unsupported command modes and invalid numeric inputs fail explicitly.

Protocol ranges follow the November 2025 model manuals. Differences from the official Python sample, temperature limitations and supported modes are documented in docs/robstride.md. Connection sends no frames. The contribution includes a B601 RS configuration, packet tests, shared host routing regression, Python regressions and reproducible mock timing measurement.

Validation: locked Rust workspace tests, Rustfmt and strict Clippy pass. The no default features host check and thumbv7em-none-eabihf embedded build pass. A release x86 abi3 wheel builds and all 28 Python tests pass from a fresh installation. Native seven motor encode and decode measured p50 170 ns and p99 260 ns. The release Python mock loop measured p50 1.03 microseconds and p99 3.59 microseconds. These exclude physical CAN latency and do not establish real time safety. Native Jetson aarch64 builds and workspace tests now pass. All 28 Python tests pass there against the release extension. Its seven motor mock loop measured p50 2.59 microseconds and p99 5.44 microseconds, with peak resident memory 34,964 KiB. Physical Pi and motor qualification remain pending. Keep this PR in draft for review and hardware validation.

Hi @ammarjmahmood thx for contribution. have you tested the implementation from your end? I don't have a robstride motor so unable to test. lmk when you think it's ready by making this ready for review!
