Computer Use Delivery State

This follow-up preserves delivery uncertainty after a native or Electron action has reached the executor.

Problems

• AX and CDP text writes became capture_failed when readback did not confirm the value, even though the write had already been delivered.
• A successful semantic action became capture_failed or sensitivity_blocked when its required fresh screenshot failed.
• A failed screenshot observation was stored before normalization and could evict an earlier usable observation.
• The model-facing description still claimed Electron text was always refused.

Fix

• Delivered but unverifiable writes and semantic actions return outcome_unknown.
• Fresh-capture errors after dispatch retain the action's delivered state.
• Observations enter the bounded FIFO only after screenshot normalization succeeds.
• The tool description documents the unique CDP click and text path.

These changes do not weaken pre-dispatch freshness, identity, occlusion, or physical-input checks.
