Note

Low Risk
Low risk: changes are primarily a version bump and additive SDK typing updates; the only behavioral change is readEnv now treats empty-string environment variables as undefined, which could affect edge-case configuration parsing.

Overview
Releases 0.48.0 by updating package/version metadata (package.json, lockfile, src/version.ts) and regenerating changelog/stats from the latest OpenAPI spec.

Adds optional base_url to browser session response types across browsers, browserPools.acquire, and invocations browser listings.

Tweaks readEnv to return undefined for empty-string values (using || undefined), aligning behavior across Node and Deno.
