waste_lens 0.1.1

Live in-app detector for wasted Flutter work — dead rebuilds, redundant API calls, memory leaks, and memory pressure. Debug/profile only, a no-op in release.

/// Minimal `waste_lens` setup: wrap your app once. The diagnostics overlay
/// appears in debug/profile; in release this is a zero-overhead no-op.
///
/// The full "Evidence Ledger" demo — one screen per module, each committing a
/// deliberate offence the overlay catches live — lives in the repository's
/// top-level `example/` directory.
