feat: support JP7 area items and world link rules

[nichinichisou0609]

Summary

• Preserve three-dimensional area-item effects, nullable ALL_MATCH rates, and master-row ordering. Add multi-unit evaluation modes shared by deck recommendations and area-item upgrades.
• Correct MySEKAI gate selection and missing-level handling, and extend area-item upgrade shop mappings through level 20.
• Apply WL3 finale limits and original-unit shuffle bonuses, preserve source support rates, and use skill caps directly from master data.
• Carry optional mixed-unit power tables through pool construction, exact search bounds, dominance, compaction, and result reporting.
• Expose the evaluation mode across typed, CLI, HTTP, and WASM APIs, with updated OpenAPI and parameter documentation.
• Fix zero-membership minimization bounds and reject out-of-range internal attribute indices before pool construction.

Validation

Validated on Windows MSVC with low-concurrency builds:

• Core library: 330 tests passed; 8 ignored.
• HTTP server: 28 tests passed.
• Independent synthetic CLI scenarios: 42 passed.
• Node execution of the WASM module: 46 scenarios passed.
• Formatting and strict Clippy checks passed for the core, server, and WASM packages. Server feature checks covered default, jemalloc, and mimalloc configurations.
• Rust 1.89 MSRV check passed.

GitHub CI additionally passed the Linux, macOS, and Windows test jobs, exhaustive search matrices, server checks, formatting/Clippy, and MSRV for the identical source tree. Browser execution and real-account data were not exercised. The local MSVC jemalloc feature check does not exercise native Linux jemalloc. Synthetic scenarios cover area items, gate selection, evaluation-mode propagation, upgrade recommendations, WL3 bonus components, and fixed-character constraints.
