* Downloads micron-parser-go WASM release assets and matching wasm_exec.js for Vite public/.

* Generates SRI hashes for integrity verification at runtime.

* Skips large downloads when upstream hashes match local files (SHASUMS256.txt + conditional GET).

* Safe to run offline: exits 0 without deleting vendor files when MICRON_WASM_SKIP=1 or network fails.

* Override URLs:

* MICRON_PARSER_GO_WASM_URL
