📝 Fix README accuracy and section order 📝

Audit found three accuracy bugs and one section ordering violation:
- Add wasm-opt (binaryen) to WASM tools table — installed via pkmgr
in 05-custom.sh but was missing from the tools reference entirely
- Fix wasm32-emscripten → wasm32-unknown-emscripten in cross-compile
targets table (wrong triple name)
- Move "Install and run container" (dockermgr) from position 10 to
immediately after "Pull" — both are production install paths and must
appear before the Development section per canonical section order rules
- Rename "Build the image locally" → "Development" to match canonical
section naming; it is the last substantive section before License
- README.md: add binaryen/wasm-opt row to WASM tools table
- README.md: correct wasm32-unknown-emscripten triple
- README.md: move Install and run container section to top (after Pull)
- README.md: rename build section to Development; move to end
