fix: add postinstall patch for @fluxstack/live bun export condition

The published @fluxstack/live packages (v0.3.0) include a "bun" export
condition pointing to ./src/index.ts, but the npm tarball only ships
dist/. On Linux, Bun's bundler strictly follows the "bun" condition and
fails with "Could not resolve" because src/ doesn't exist.

This adds a postinstall script that strips the "bun" condition from
package exports, forcing Bun to fall back to the "import" condition
(./dist/index.js) which works correctly on all platforms.

TODO: Remove after publishing @fluxstack/live >= 0.3.1
