Reconstruct SB4E01 source through 1.75% integration

[ekoka99]

This adds cumulative SB4E01 source reconstruction and integration across LiveActor, Map, collision, geometry, and supporting utilities. Verified source-integrated code reaches 109,996 / 6,281,816 bytes (1.7510222%), with 272 complete translation units. Exact objdiff code is 168,616 bytes and 1,692 functions; these metrics include original-linked matches and are distinct from source integration.

The changes include source ownership splits, symbol/alignment corrections, supporting declarations, and provenance. Partial implementations remain original-linked. The README and published progress assets retain the earlier 1% milestone snapshot; current verified figures are above. This is an intermediate mixed-source checkpoint, not a fully source-built game.

Validation on the cumulative working tree:

• Built with the configured compiler through the local wibo wrapper.
• Generated an explicit objdiff report and checked incoming and historical exact-match regressions.
• Compared accepted routines instruction by instruction, including dependency symbols, linked addresses, source selection, and retail padding.
• Full main.dol byte comparison against retail passed; SHA-1: 7d79810889824edd01c4ff02624713060a69818c.
• Applied the normalized cumulative patch against upstream baseline 8dcedb269f4b9164bda6dd11768be1ccd9bb126b and verified every publication file against the tested tree after encoding normalization.

The local Shift-JIS runner override is excluded. No retail assets or toolchain binaries are included. No gameplay testing was performed. Direct retail reconstruction and external adaptations are distinguished in docs/PROVENANCE.md.

mistakes

Yeah, no. I am not reviewing this behemoth. This is also very ai-generated. These files should be split properly before we even consider decompiling. Closing.

It is worth noting that we will focus more on SMG2 once 1 is completed, which shouldn't take much longer.
