Bring the docs up to date and keep each in its lane:
- README (overview): both programming paths (Xilinx proxy flash + SVF),
probe profiles, neutral JTAG clock + per-device cap, runtime YAML
registry, IGLOO2 bundled; run-from-repo-root fixed
- tutorial (user view): probe profiles + jtag_close, the prog tag, a
JTAG-clock section, a new "Programming via SVF" section, prog/max_tck
in the add-a-target table, troubleshooting rows
- CLAUDE.md (design): architecture tree lists the project modules + YAML
data files; roadmap gains phases 5 (probes/JTAG-link) and 6 (SVF)
