probes: add probe-config profiles loaded from probes.yaml

Browse Source 
- new modules/probes/ parses probes.yaml (libyaml): a defaults: map
  applied on every jtag_open + named profiles: selected with
  `jtag_open <idx> <profile>` (jtag_profiles lists them); each value is
  pushed into the script envvar store the driver reads at open time
- ships a flashpro profile (ADBUS4 high-Z) that lets the IGLOO2 kit's
  embedded FlashPro (FT4232H, port 0) detect the chain
- CLAUDE.md: decision entry for probes.yaml + a design note on the
  probe / JTAG-link / device config strategy (driver-neutral link layer)
