TCP/IP and Packet Validation Examples

Summary

This PR adds hardware-focused validation flows to the template project for both socket robustness and generated packet parsing.

• Adds ExampleTCPIP, a full Ethernet stress example covering TCP server/client, UDP traffic, reconnect behavior, bursts, and health telemetry.
• Adds ExamplePackets, a generated packet/order validation example built on OrderPackets and DataPackets.
• Adds host-side tooling for automated validation, including stress, quality-gate, soak, and packet-check scripts.
• Adds tools/build-example.sh to simplify building examples and selecting named TEST_* variants.
• Expands documentation with per-example guides and deeper TCP/IP testing references.
• Stops tracking generated packet headers (DataPackets.hpp, OrderPackets.hpp) and documents them as build artifacts.

Impact

This makes the template project much more usable as a hardware validation base: examples are easier to build, Ethernet behavior is easier to stress automatically, and generated packet parsing can be verified end-to-end against the active schema.

Validation

Validated with a Nucleo Development Board using repeated TCP/UDP stress runs, packet parsing checks, reconnect scenarios, and long-duration soak workflows (yes, thanks to Chatty to create those scripts)

Notes

Yes, I also made the fix of the fix of the fix of the fix of the fix of the fix of the fix of the fix "a puntito de caramelo" "ahora si que si chicos" "esta va confiar" "esta es la definitva" "3.0" @Cantonplas
The Packet generator is now parsing properly the int types, not only de uints

Pull request overview

Adds hardware-focused TCP/IP stress testing and generated packet/order validation examples, plus host-side automation scripts and documentation, to make the template project a more complete hardware validation base.

Changes:

• Introduces ExampleTCPIP (firmware) and a host-side Python stress harness with quality-gate/soak runners.
• Introduces ExamplePackets (firmware) and a host-side checker driven by the active JSON packet schema.
• Adds tools/build-example.sh, expands docs, and gitignores generated packet headers.
