fix(acp): set CLAUDE_CODE_EXECUTABLE to fix musl binary resolution

The v0.30.0 adapter resolves its native binary via require.resolve()
on platform-specific optional deps. On Linux it tries the musl
variant first; if that file exists but the musl loader is missing,
the binary silently fails to execute, causing "Failed to create ACP
session". Setting CLAUDE_CODE_EXECUTABLE to the system-installed
claude binary sidesteps this entirely.

Also adds @latest suffix to the package name to force bunx to resolve
the correct scope instead of a stale @zed-industries cache entry.
