Promote daKrpa_c as a genuine class TU

[andrewboudreau]

Dependency

Stacked on #2000. After it merges, this branch will be rebased onto current main.

Summary

• promote ov070/daKrpa_c from 25 one-function sources into src/actors/daKrpa_c.cpp
• let mwccarm emit the real D1/D0 lifecycle, vtable, RTTI, SpawnInfo, and typed class behavior; no D2 or generated destructor shells remain
• replace local shadows, raw actor offsets, and manual lifetimes with typed members and genuine C++ calls where exact, retaining only documented ABI seams

Verification

• tubuild verify: 25/25 MATCH, objisolate clean, relocation destinations clean
• emission order: all 25 functions in ROM order; compiler-only Vector3 D1 is exact and fail-closed
• romdata_check: 4 VERIFIED, 6 PARTIAL, 0 DIFFERS, 0 UNNAMED
• check_src_tu_compiles: 88/88
• full rombuild.py -j 16: 11,085/11,085 reproducing, 0 mismatches, 106/106 modules exact, 0 ROM-gap fallback, PASS
• port, dead-reference, header-offset, language-mode, converted-tier, TU-state, reference, and attribution gates pass; 25/25 credits preserved

Byte-verified means the range carries complete in a delinks.txt, so the ROM build compiled it and compared it to the cartridge. The 218 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 11,216 this project calls matched.

Warnings: 25 address range(s) left the byte-verified set while enrolled totals held steady: ov070:0x02121118-0x02121160, ov070:0x02121160-0x021211bc, ov070:0x021211bc-0x021211c4, ov070:0x021211c4-0x02121298, ov070:0x02121298-0x02121310, +20 more; 24 more function(s) now claim a match that nothing compiles; enroll them in a delinks.txt to have the ROM build check them.

Per-file link-check detail

All 1 changed file(s) compile to the ROM byte-for-byte with correct relocation targets.
