twiggy-related utilities (#4569)
* feat(query-engine-wasm): move wasm-opt options from Cargo.toml to build.sh, to share subset of it between multiple build profiles * feat(query-engine-wasm): add wasm-inspect.sh to analyse human-friendly WebAssembly code (*.wat) * chore: fix shellcheck SC2155 * feat(query-engine-wasm): default to "dev" profile; one can still opt in for WASM_BUILD_PROFILE="profiling" * feat(query-engine-wasm): update README.md
