[codex] Add Microchip USB PID supplement

[zackees]

Summary

Adds Microchip / Atmel USB PID ingestion for the online-data refresh.

• adds fetch_microchip_usb_pids.py with explicit --tier first-party, --tier supplemental, and --tier all modes
• first-party tier parses Microchip-maintained pyedbglib and pykitinfo
• weak supplemental tier parses AVRDUDE plus selected Arduino/LowPowerLab board package rows after stronger sources
• wires both tiers into the nightly workflow and documents the source priority/caveats

Notes

Third-party SDK/package data is intentionally weak: it fills gaps after Microchip first-party and generic USB-ID data, but does not override them.

The README also records the LowPowerLab current_ranger mismatch: the current external package maps CurrentRanger to 04d8:ee44/ee48/ee4c, while local FastLED board JSON carries current_ranger as 04d8:eee5.

Closes #728.

Summary by CodeRabbit

• New Features
  • Added support for collecting and merging additional Microchip USB PID data into the aggregated USB device catalog.
  • Added a new data-fetching utility for Microchip USB VID:PID records with tiered output options.
• Bug Fixes
  • Improved handling of partial data updates so available sources can still be included when some fetches fail.
• Tests
  • Added coverage for Microchip USB PID parsing, merging, and command-line output.
• Documentation

📝 Walkthrough

Walkthrough

Adds fetch_microchip_usb_pids.py, a new Python script that fetches Microchip/Atmel USB VID:PID data from pyedbglib, pykitinfo, AVRDUDE, Arduino boards, and LowPowerLab sources across two tiers (first-party and supplemental). Both tiers are wired into the update-data.yml workflow. A pytest suite validates all parsers using network-free fixtures. README is updated accordingly.

Changes

Microchip USB PID Ingest

Layer / File(s)	Summary
Constants, data shapes, and regex patterns online-data-tools/fetch_microchip_usb_pids.py	Defines VID constants, upstream URLs, PYEDBGLIB_PRODUCTS mapping, AvrdudeEntry dataclass, AVRDUDE_PRODUCTS table, and compile-time regex patterns for all parsers.
HTTP fetch helpers and mapping utilities online-data-tools/fetch_microchip_usb_pids.py	Implements _fetch_text/_fetch_bytes, _vendor_for_vid, PID-to-entry converters, supplemental merge helper, and product name normalization.
First-party parsers: pyedbglib and pykitinfo online-data-tools/fetch_microchip_usb_pids.py	Implements parse_pyedbglib_toolinfo (regex with validation) and parse_pykitinfo_tools (AST-based resolver with CDC/name normalization), plus _literal_with_names.
Supplemental parsers: AVRDUDE, Arduino boards, LowPowerLab online-data-tools/fetch_microchip_usb_pids.py	Implements parse_avrdude_usbdevs, _collapse_board_products, parse_arduino_boards, and parse_lowpowerlab_package with ZIP extraction.
Tier dispatch, collect functions, and CLI main online-data-tools/fetch_microchip_usb_pids.py	Implements collect_first_party, collect_supplemental, collect tier dispatcher, main() CLI with argparse and JSON output.
Test fixtures and pytest suite online-data-tools/test_microchip_usb_pids.py	Network-free string/zip fixtures and pytest tests covering all parsers, collect tier precedence, and main() via monkeypatching.
Workflow wiring and README docs .github/workflows/update-data.yml, online-data-tools/README.md	Adds two continue-on-error fetch steps (first-party and supplemental) to the workflow, conditionally merges their outputs, updates the summary table, and documents the script in README.

Poem

🐇 Hop hop, the PIDs align,
From pyedbglib's constants so fine,
AVRDUDE, Arduino too,
Each tier fills gaps right on cue,
No duplicate shall override,
With JSON sorted, test-verified! ✨
