fix(e2e): harden input-ingestion wait against bursty rendering

3956809→main·

pfleidi·2w ago·2 files·+16 added/-5 removed

Require two consecutive stable polls in waitForInputIngested so a single quiet interval mid-paste can't fake stability, and document why it compares raw captures instead of stableContent. Re-print the vogon prompt when ignoring an empty line so manual REPL sessions stay readable.

Addresses PR #1599 review feedback.

// waitForInputIngested waits until the pane content has changed from preSend

// polls (the TUI's input handler has caught up), then returns the settled
// content. Gives up after 15s and returns the last capture.
// (the echoed input is visible) and held still for two consecutive polls
// (the TUI's input handler has caught up — droid renders long pastes in
// bursts, so a single quiet interval can fake stability), then returns the

// Compares raw captures: the input box lives in the bottom lines that
// stableContent strips, so stable comparison would be blind to the echo.
