Fix npm install by requiring the linux payload

The 0.129.10 meta package put the only published linux-x64 native payload in optionalDependencies. Some global installs can leave that optional alias missing, which makes the launcher fail before it can find the native codex binary.

When the release script is explicitly constrained to a platform payload, emit a hard dependency instead. Keep the default multi-platform path optional so full platform builds can still skip incompatible native packages.

Also bump the release version to 0.129.11 for the npm recovery publish.
