Promote daObjKm3_Kaitendai_c intact translation unit

[andrewboudreau]

Replacement for #2111, which was reviewed and validated but merged into the superseded #2109 branch rather than main. This is the same Kaitendai source promotion re-cut as one commit on the clean #2103 tooling head.\n\nPromotes five legacy functions into one genuine typed C++ translation unit. mwccarm emits D1/D0, RTTI, type name, descriptors, and vtable storage; the manifest keeps inherited RTTI copies exact-externalized and preserves the measured non-text section order.\n\nFresh validation at dedaed4:\n- strict TU text: 5/5 exact with relocation destinations clean\n- full production: 11,088/11,088 functions, 3/3 source-owned data claims, 106/106 modules, zero mismatches, exact stock ROM\n- strict control: 11,060/11,060 and the same stock ROM\n- nine symbol diagnostics identical in control and candidate; zero new errors\n- all 97 C++ TUs compile; port references 405/405\n- header fan-out: one source, zero blocking link failures\n- attribution: four consolidated legacy credits retained; generated state note current\n\nNo claims, attempt-ledger, or dashboard artifacts are included.

Byte-verified means the range carries complete in a delinks.txt, so the ROM build compiled it and compared it to the cartridge. The 440 claimed functions have a src/ file named after the symbol with no NONMATCHING banner, and nothing compiles them -- dsd fills their addresses with the ROM's own bytes. Both together are the 11,217 this project calls matched.

Recovers the stranded #2111. Verified independently, merging.

#2111 was reviewed and validated but merged into #2109's branch, which was superseded — so the Kaitendai promotion never reached main. This re-cut is the recovery, and it retargeted to main cleanly the moment #2103 landed.

Independently measured, not taken from the body:

premerge, base origin/main @ f7fccf68d0bf, merge tree 81df5cb86656
  all 8 static gates  pass -> pass
  source-coverage info: entries 10814 -> 10811 (-3)  consolidation, bytes flat

full build of main + this PR:
  source-built functions: 11,088   reproducing: 11,088   mismatching: 0
  source-owned data claims: 3  (reproducing 3, mismatching 0)
  module fidelity: 106/106 exact, 100.000000%
  intact TU gates: dsd modules PASS, zero new symbol errors, storage aliases exact
  ROM data from source: 529 verified (527 -> 529, +2 from this TU)
  ROM-build analysis: PASS

The -3 on source-coverage is five legacy files collapsing into one TU; code bytes are unchanged, which the 11,088/0 confirms.

One thing I checked and want on the record: I tried to land this without #2103, to avoid the stack. It does not build — _ZTI20daObjKm3_Kaitendai_c and data_ov047_02112334 link at each other's addresses and all eight .data relocations follow the swap. The dependency on #2103's manifest section ordering is real, so the original stacking was correct.

Merging.
