/**
 * File system abstraction (browser stub).
 *
 * This stub is used in browser/bundler builds via the package.json browser
 * field. Async operations are no-ops; sync operations are no-ops that return
 * safe defaults. Higher-level consumers (e.g. prompt_cache/fs.browser.ts) may
 * still throw on their own if browser use is unsupported at that layer.
