v0.1.7 — UI improvements, bug fixes & Opus 4.7

Collapsible tool call list — ▸ Working... (12) collapsed by default, click to expand/collapse
"Working..." input placeholder with subtle red border while agent is running
Long file paths truncated with ellipsis — no more horizontal overflow

Stop button correctly reappears when CLI times out and agent retries automatically
Permission cards auto-cancelled on Stop — no more orphan "Allow once / Reject" cards
clearChat now resets streaming state, buttons and placeholder correctly
Session load restores manual mode — loaded sessions no longer inherit wrong mode
Process exit rejects pending requests — eliminates infinite hangs on CLI crash
cancelAndSend state fix — suppression flag correctly reset on error
Duplicate event listener fix — initClient() is idempotent, no more stacked listeners
Settings panel preserved while user types API key (no longer wiped on config update)
Copy button shows "Failed" on clipboard permission error instead of silently doing nothing
