v0.4.0

Added

• Snapshot filters — --compact (strips bbox/selector), --limit <n> (max elements), --viewport-only (elements in viewport), --filter <expr> (by role/tag/name), --uid <uid> (single element). All available on the cloak snapshot command. (O2)
• Snapshot iframe support — --frames flag includes elements from same-origin iframes in the snapshot result, with an origin field for disambiguation. (O4)
• cloak batch command — Execute multiple daemon RPCs from stdin JSON lines. Supports --session <sid> (default session) and --abort-on-error. Guards: CLOAK_BATCH_MAX_BYTES (1MB) and CLOAK_BATCH_MAX_LINES (200). (O1)
• wait --stable — New wait condition using MutationObserver to detect DOM stability. Configurable quiet period via --quiet-ms (default 500ms). Returns { stable, mutations }. (O5)
• Shared SNAPSHOT_TAGGER_SCRIPT — In-page element tagger extracted to params.ts, shared between page.snapshot and maybeSnapshot to eliminate code duplication. (R2)

Fixed

• Missing stable in wait error message — Error prompt now lists stable as a valid wait condition. (O5 cleanup)

Changed

• Default RPC timeout — DaemonClient.call() now defaults to 30s timeout instead of no timeout. Can be overridden per-call. (O3)
• Code deduplication — Removed duplicate optStr/reqStr definitions from eval.ts and network.ts; all daemon methods now import from params.ts. (R1)
