Link ov023 actor sections from one intact TU

[andrewboudreau]

Summary

• make src/actors/daObjFm_Battan_c.cpp the intact owner of ov023's actor .text, .init, .ctor, class .data, and resource .bss
• generate the retail static initializer and destructor-registration topology organically from two C++ resource-handle globals
• retain the independently extracted old level-data bands as ROM-gap linker inputs
• record exact section, relocation, symbol-binding, address-point, and source-name provenance in the TU manifest

Stacked on #2170. This PR should be retargeted to main after the tooling PR merges.

Validation

• python tools/tubuild.py linkcheck --baseline --clean -j 16 — 106/106 modules exact; stock 16 MiB ROM SHA-256 reproduced
• python tools/tubuild.py linkcheck ov023/daObjFm_Battan_c --clean -j 16 — all 5 owned ranges, 9/9 functions, and 48 non-text relocations exact; 0 new symbol errors; full ROM identical to strict control
• python tools/rombuild.py -j 16 --no-rom — 11,088/11,088 functions, 10/10 data claims, 40-byte BSS claim, and 106/106 modules exact
• python tools/cpp_tu_compat.py --require-ready — READY
• python tools/prepush_attribution.py --base tools/intact-multisection-tu --head cpp/ov023-complete-overlay — 0 changed, 0 lost
• pre-push gates — 405/405 port references and 98/98 reconstructed TUs compile

The repository-wide symbol checker still reports the same nine pre-existing control errors; this candidate introduces zero new errors.

Byte-verified means the range carries complete in a delinks.txt, so the ROM build compiled it and compared it to the cartridge. The 582 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.

Warnings: contributor attribution changed, not a blocker (1 changed, 0 lost -- src/actors/daObjFm_Battan_c.cpp: tangosdev -> andrewboudreau); 1 linkcheck result(s) have unresolved relocations.
