fix(ci): fix macOS Intel build and Linux ARM64 cross-compile

- macOS: Source cargo env before build to ensure Rust in PATH
- Linux ARM64: Use zig for cross-compilation from x86_64
- pathResolver: Use EnvConfig.workspaceRoot for env var compat
  (Fix: TAPTAP_MCP_WORKSPACE_ROOT was not being read because
   pathResolver directly used process.env.WORKSPACE_ROOT)
