4ee1c2b631 probes: add probe-config profiles loaded from probes.yaml
- 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)

00320d87ec script: add jtag_close to release the current probe
Lets a session hand a probe back (frees its USB handle) without opening
another, e.g. to flash two FPGAs on different probes in turn:
jtag_close, then jtag_open the next one and jtag_autoinit. Mirrors the
DeInit teardown jtagcore_loaddriver already does when switching drivers.

Also fix the help printer: no-arg commands (whose params slot is "")
printed an empty body because "" was treated as the terminator. Params
are now optional and the description always shows.

3579c5efb0 fpga: load registry from yaml at runtime, not compile-time
- registry moves from the array in fpga.c to fpga_registry.yaml at the
  repo root, parsed via libyaml (pkg-config yaml-0.1); adding a part is
  now a YAML edit, no rebuild
- looked up CWD-relative (like bsdl_files/), overridable with
  $BS_FPGA_REGISTRY, loaded lazily once; public API unchanged
- fpga_list shows the source file (fpga_registry_source())
- add microsemi_igloo2/smartfusion2 and lattice_machxo2/3 families,
  ready for the non-Xilinx targets
- docs updated: CLAUDE.md, README, tutorial "add a target" walkthrough

4b924629be doc: update README for the proxy flash path and current state
Reflect what now works: per-FPGA registry, BSCAN proxy SPI bridge, and
flash detect/read/erase/program/verify (~100 KB/s). Switch the typical
flow to the proxy path, add the fpga/bscan/flash command rows, note
persistent history, the KU040 BSDL, the new modules + bscan_proxies/ in
the layout, and the quartiq MIT proxies in the license section.

8e3428788c build: Digilent backend on by default on UNIX
The driver dlopen's libdjtg/libdmgr and degrades to "no probe" if
they're absent, so building it in has no cost or dependency.
BS_ENABLE_DIGILENT now defaults ON on UNIX (needs <dlfcn.h>); disable
with -DBS_ENABLE_DIGILENT=OFF. Docs updated; also fixes the quartiq
license note in CLAUDE.md (MIT, not BSD-2).

952c010c63 script: shorten jtag_* command names
Drop the get_/set_/_pin/_list noise from the JTAG commands (e.g.
jtag_get_probes_list -> jtag_probes, jtag_set_spi_cs_pin -> jtag_spi_cs,
jtag_spi_rd_wr -> jtag_spi_xfer). jtag_open_probe -> jtag_open (not
jtag_probe, which would clash with jtag_probes under tab-completion).

Hard rename, no aliases. Updates the state-dump emitter, help text,
example script and docs accordingly.

cacbb9d00e doc: document Digilent backend and probe-open by index
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.

1febae7377 doc: add end-to-end tutorial
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.

7cb3627754 phase 1: cleanup, REPL polish, README
- fix format-string in jprint/script_print (printf(msg) -> fputs)
- fix bsexp_deinit: deinit_script guarded by sctx, not jc
- silence "config.script not found" when the optional override is absent
- remove dead code: bs/cmds/, bs/args.{c,h}, bs/utils.h, commented blocks
- REPL: welcome banner with version, readline tab-completion on
  script_commands_list, skip blank lines, clean Ctrl-D exit
- README: build, REPL usage, typical SPI flow, command table, probes,
  Xilinx STARTUPE3/CCLK caveat
