fix(cli): point @socketaddon/iocraft file: ref at the template, not gitignored build output

The previous file: ref pointed at
`packages/package-builder/build/dev/out/socketaddon-iocraft`,
which is gitignored — the directory only exists after running
`pnpm --filter package-builder run generate:socketaddon`. In a
fresh checkout or git worktree, the path doesn't exist, and pnpm
v11.0.0 GA's `verifyDepsBeforeRun: install` default flushed this
out: every pnpm-prefixed command pre-flight-installs and trips on
`ERR_PNPM_LINKED_PKG_DIR_NOT_FOUND`.

Repoint to `packages/package-builder/templates/socketaddon-main`,
which IS committed (it's the handlebars-free static template the
generator copies into the build output). Same files,
byte-identical content: package.json declares
@socketaddon/iocraft@1.0.0-pre.0 with the per-platform native
addons as optionalDependencies, and the index.mjs does runtime
platform detection + require() of the matching .node binary.

Tests that depend on the native .node binary still need the per-
platform addon to be present (built by the package-builder Rust
generation step); that's a separate concern from install-time
resolution.
