fix(rp2040): encode complete firmware at XIP address

[zackees]

Correct the RP2040 UF2 base for fbuild's complete firmware.bin. The image includes boot2 at 0x10000000; 0x2000 is only valid for app-only BINs. Add a boot2-prefix regression test and document the FastLED/boards-only VID/PID policy. Closes the incorrect-address portion of #1040; do not claim hardware acceptance until a real 2E8A:000A CDC endpoint is observed.

Summary by CodeRabbit

📝 Walkthrough

Walkthrough

The PR documents FastLED/boards as the authoritative USB VID/PID source and revises fixture refresh guidance. It also changes RP2040 UF2 full-image encoding to use the XIP address base and adds coverage for boot2-prefixed firmware.

Changes

USB VID/PID source documentation

Layer / File(s)	Summary
Registry source and fixture guidance CLAUDE.md, crates/fbuild-core/data/README.md	Rules and documentation require production VID/PID data to come from the FastLED/boards registry, distinguish test fixtures from runtime catalogues, and describe downloading published artifacts into the build cache.

RP2040 UF2 full-image encoding

Layer / File(s)	Summary
Full-image XIP address encoding crates/fbuild-deploy/src/rp2040.rs	RP2040_UF2_BASE_ADDRESS now uses 0x1000_0000; a test verifies the address and payload for a boot2-prefixed full image.
