CLAUDE.md/README/tutorial: optional BS_ENABLE_DIGILENT backend, why
SMT2 modules need libdjtg, and the new jtag_open_probe index. Mark
phases 2 and 2.5 done.
doc/tutorial.md walks from probe detection to JEDEC ID over EXTEST and
forward-references the BSCAN proxy path. Includes:
- prerequisites and build/launch
- chain scan, FPGA identification, registry lookup
- IR/DR primitive sanity check via the IDCODE register
- SPI JEDEC ID over EXTEST (with the speed caveat)
- recipe to add a new FPGA target
- troubleshooting cheat sheet
README and CLAUDE.md updated to point at it.

Durable project context (architecture, roadmap, key decisions, external
references, commit conventions) so any Claude Code session on any
machine has the same baseline understanding. Machine-local facts stay
out of the repo, in ~/.claude/.
