opencode 1.19.3 for macOS 11 (Big Sur) x86_64

Patched opencode 1.19.3 that runs on macOS 11 Big Sur (x86_64).

Built with build.sh + build-sqlite.sh from the official opencode-darwin-x64@1.19.3 binary.

Assets:

• opencode-1.19.3-darwin-x64-bigsur.tar.gz - opencode + libicu.dylib + libsqlite3.dylib
• libicu.dylib - ICU compatibility shim (system ICU 66 is missing 11 symbols)
• libsqlite3.dylib - SQLite 3.50.4 (system 3.32 lacks RETURNING/jsonb)

Install on the Big Sur Mac:
mkdir -p ~/opencode ~/lib
tar xzf opencode-1.19.3-darwin-x64-bigsur.tar.gz -C ~/opencode
mv ~/opencode/libsqlite3.dylib ~/lib/
export PATH="$HOME/opencode:$PATH"

Verified on macOS 11.7.10 x86_64: version, models, chat, and tool calls.
