perf: use lzma-wasm for SWF decompression and drop vite

Replace the pure-JS lzma decoder with lzma-wasm (Rust/WASM, base64-inlined,
zero-alloc decompress), giving an order-of-magnitude speedup on furni
imports. Remove the obsolete lzma type shim and the redundant top-level
vite dev dependency, which nothing imports directly.
