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

/**
* rpi5_native_entry.h - Raspberry Pi 5 native (non-UEFI) boot entry point
* (FABRIC-3.md §IV.3 item 1).
*
* `native_rpi5_entry.S`'s `rpi5_native_start` is the very first code that
* runs on this path -- entered directly by Pi 5 firmware, no UEFI, no
* ACPI, none of `boot/uefi_loader.c`'s PE-loader shape applies. It masks
* the firmware's raw entry register down to the documented 32-bit DTB
* pointer (§IV.1: upper 32 bits of the 64-bit register are unspecified)
* and stores it here, then establishes its own dedicated stack (this path
* has no EDK2 boot stack to inherit) and halts.
*
* `g_rpi5_dtb_ptr` is this stub's one real output -- the still-open
* DTB->BootInfo constructor (§IV.3 item 2) reads it from here once it
* exists; nothing calls that constructor yet, so `rpi5_native_start`
* halts rather than tail-calling into a function that isn't real.
