rajamesandClaude Opus 5.5 a28b5f2230 fix(v4): the final review's six minors in the ROM boot
- Text after start is refused, as text.c refuses it: before it jumps, the
  ROM reads on to the end of the source; blanks, comments and the ends of
  blobs may follow, a token is ERR-AFTER (26), "text after start".
- A token too long where a name, a target or a value is wanted is "name
  too long", as text.c says: (MISSING) reports "missing" only when no error
  came first.  `", keeps "missing", which is text.c's word for both.
- text.c's "address out of range" names the address, not the value.
- The system's source files are one list, v4/sys_files.h: boot.c, the
  harness and the nucleus test are made from it.
- The ROM's error codes and words are one list, v4/rom_errors.h: boot.c's
  messages, host_map.h's ROM_ERR_* and mkmap's ERR-* are made from it.
- node.h says what v4_node_store does with a ROM address (nothing, as for
  any address outside RAM, D-14); test_host_rom_range pins it.

ROM: 2095 words, rom_hash 0x06d0dcb7a0cb41a1.  dict_hash unchanged,
0xe5a57f3eb72ff94a.  make -C v4 test test-32 hosted-check pass.  QEMU:
amd64, aarch64, riscv64 to ok>, POST 538/538, POST: PASSED.

/* rom_errors.h -- the ROM's error codes and what they mean.
*
* The ROM (capsules/v4/rom) stops at (ROM-FAILED) with one of these codes in
* (FAILED); the loader, which owns the console, prints its words
* (v4/system/boot.c). This is the one list: the map's constants ERR-* the
* ROM is assembled with (v4/tools/mkmap.c, through v4/tests/host_map.h's
* ROM_ERR_*) and the boot's messages are both made from it. The codes run
* 1, 2, 3 ... in order; a new one goes at the end.
*
* X(NAME, CODE, WORDS)
