Restructure in anticipation of programming ARM CPUs (ARM7/9 via
EmbeddedICE, e.g. over an Olimex ARM-USB-OCD); FPGA path unchanged.
- modules/fpga -> modules/target; fpga_target -> jtag_target with a
`kind` (fpga|cpu) and grouped fpga/cpu sub-structs; data/targets.yaml
(env BS_TARGETS); API target_*; commands target_list/target_info
(kind-aware). Add arm7/arm9 families, arm_flash prog, embeddedice
debug, and cpu fields (ram_base/size, flash_base/size).
- new program/: `program <dev> <file>` dispatches by the target's prog
(svf wired; proxy_spi points at the flash workflow; arm_flash -> arm_debug).
- new arm_debug/: EmbeddedICE halt/resume/mem + arm_flash backend
declared, not implemented yet.
- bscan_* take const jtag_target* and read the fpga sub-struct.
- data/probes.yaml: arm-usb-ocd profile slot; data/targets.yaml: an ARM7
example entry. Docs + an ARM-debug design note in CLAUDE.md.
Builds; FPGA path re-validated on the IGLOO2 (target_list shows the CPU
example; jtag_open/autoinit/program 0 <svf> all work).

Separate the two concerns the repo root was mixing:
- src/ — bs/, modules/, libs/ (code + vendored libs)
- data/ — fpga_registry.yaml, probes.yaml, bsdl_files/, bscan_proxies/,
scripts/ (everything the tool reads at runtime, CWD-relative)
- doc/ — kept at the root
CMake: repoint DIR_MODULES/DIR_LIBS and add_subdirectory at src/; emit
the binary at the build/ root (build/bs) via CMAKE_RUNTIME_OUTPUT_DIRECTORY
instead of the nested build/src/bs/. The jtag_core ../../libs path still
resolves since modules and libs moved together.
Runtime default paths now point under data/ (fpga.c, probes.c, script.c
bsdl_files lookup, init.c config.script). Docs (README/tutorial/CLAUDE)
updated for the new layout, src/ module paths, and ./build/bs.
Validated on the IGLOO2/FlashPro: profiles, autoinit, and svf_play all
work run from the repo root.
