[prathikr]

allows users to do npm install foundry-local-sdk-winml and then do import { FoundryLocalManager } from 'foundry-local-sdk'; like the other SDKs do

Pull request overview

This PR restructures the JS WinML variant into a thin wrapper package (foundry-local-sdk-winml) that depends on foundry-local-sdk, intending to let users install the WinML variant but continue importing from foundry-local-sdk while swapping in WinML native binaries.

Changes:

• Updates the packaging script to publish foundry-local-sdk-winml as a wrapper that depends on foundry-local-sdk and does not ship dist/.
• Updates the WinML install script to target the standard SDK’s installation directory for native binary placement.
• Extends the shared install utilities to support installing binaries into an explicit SDK root (rather than only this package’s own directory).

File	Description
sdk/js/script/pack.cjs	Converts the WinML package into a thin wrapper (no dist/, depends on foundry-local-sdk).
sdk/js/script/install-winml.cjs	Attempts to run preinstall + download WinML-native binaries into the standard SDK’s platform directory.
sdk/js/script/install-utils.cjs	Adds sdkRoot support to direct extraction to a different @foundry-local-core/<platform> directory.

• runInstall() returns early if the required files already exist and npm_config_nightly isn’t set. For the WinML wrapper use-case (overwriting an existing standard install), this prevents the WinML artifacts from ever being applied. Add an explicit force/overwrite option (or a check that detects whether the existing Core is the WinML variant) and use it from install-winml.cjs.

async function runInstall(artifacts, sdkRoot) {
    if (!RID) {
        console.warn(`[foundry-local] Unsupported platform: ${platformKey}. Skipping.`);
        return;
    }

    const binDir = sdkRoot
        ? path.join(sdkRoot, 'packages', '@foundry-local-core', platformKey)
        : DEFAULT_BIN_DIR;

    if (fs.existsSync(binDir) && REQUIRED_FILES.every(f => fs.existsSync(path.join(binDir, f)))) {
        if (process.env.npm_config_nightly === 'true') {
            console.log(`[foundry-local] Nightly requested. Forcing reinstall...`);
            fs.rmSync(binDir, { recursive: true, force: true });
        } else {
            console.log(`[foundry-local] Native libraries already installed.`);
            return;
        }
