rajamesandJunie a8b70e88d3 Reorganize source tree: kernel/, v3/, v4/ split and board infrastructure
Source tree reorganization:
- Move StarForth v3 engine to v3/ (src/, include/, Makefile)
- Move kernel to kernel/ (src/, include/, linker/, Makefile)
- Create v4/ skeleton for F18-ISA golden model (DECOMPOSITION.md, JUSTIFICATION.md)
- Move FABRIC-0..4.md to docs/fabric/
- Move ONTOLOGY.md and ROADMAP.md to docs/

Board infrastructure:
- Add boards/ser5/, boards/raspi/, boards/milkv/, boards/zynq7020/
- Each board has board.mk (ISA, CPU flags, boot recipe) and README.md
- Root Makefile becomes thin dispatcher: boot_image, all, clean, docs take TARGET
- make boot_image TARGET=SER5|RASPI|MILKV builds one GPT/MBR image per board
- ZYNQ7020 target exists but stops with clear error (ARMv7 port not built yet)
- scripts/mkdiskimage.sh builds disk images for all boards

Docs pipeline:
- docs/book/ with LaTeX master (main.tex) and Makefile
- pandoc converts Markdown to LaTeX at build time
- Two Lua filters: table-widths.lua (wide tables wrap), code-breaks.lua (inline code breaks)
- make docs builds single PDF (754 pages, 0 missing characters)
- make docs TARGET=<board> adds board appendix
- build/docs/<book|board>/meta.tex stamps git commit into PDF

Bug fixes:
- 42 include paths that only worked by accident now use correct relative paths
- clang-18 hardcode replaced with configurable CC variable (fixed aarch64 build)
- Pi 5: kernel_2712.img linked at 0x80000, .bss zeroed, memory reserved
- Doxyfile, .clang-tidy, README.md, Kconfig paths updated

Verified:
- Hosted v3 build passes 1012 tests, 0 failures
- SER5 image boots in QEMU (OVMF), POST passes, K exact (65536 = Q48_ONE)
- Milk-V image boots in QEMU (OpenSBI + U-Boot + bootefi), POST passes
- make clean TARGET=<board> removes only that board and its ISA objects
- make all builds all boards, hosted v3, and docs in one run

/*
* zuse_genesis_marker.h -- on-disk record format for the system-resident
* "a root Zuse identity already exists" marker (FABRIC-2.md §F.21),
* stored in devblock_from_top=0 of the top-of-device system-metadata
* fence (block_subsystem.h's blk_meta_zone_read()/write(), same location
* zuse_cert_devblock_t used to occupy).
*
* Supersedes zuse_cert_devblock_t (zuse_cert_devblock.h, kept in the repo
* as historical record, no longer written): that type stored Zuse's own
* *seed* system-resident. Under the thumbdrive-resident Zuse design
* (§F.20/§F.21), the seed lives only on Zuse's own minted thumbdrive --
* this record deliberately holds only her *public* key, enough to (a)
* know genesis has already happened, so a second blank thumbdrive
* attached on some later boot never mints a second competing root, and
* (b) recognize which attached identity is genuinely hers. Losing this
* fence record is not a security problem (it's not a secret); losing the
* thumbdrive itself is what actually loses the identity.
