fix: add --force to npm/pnpm/bun upgrade to prevent stale native binaries

Without `--force`, package managers may serve cached platform binaries from
`@altimateai/altimate-core`'s `optionalDependencies`. The caret range (`^0.2.5`)
lets npm skip re-downloading if the cached version satisfies the range, even when
a newer version with additional exports exists. `--force` ensures all dependencies
are re-resolved and re-fetched from the registry during auto-upgrade.
