Tool hints should be kept as permanent content in the streaming card
so users can see which tools were called (matching the standalone card
behavior). Previously, hints were stripped when new deltas arrived or
when the stream ended, causing tool call information to disappear.
Now:
- New delta: hint becomes permanent content, delta appends after it
- New tool hint: replaces the previous hint (unchanged)
- Resuming/stream_end: hint is preserved in the final text
Updated 3 tests to verify hint preservation semantics.

Three fixes for inline tool hints:
1. Consecutive tool hints now replace the previous one instead of
stacking — the old suffix is stripped before appending the new one.
2. When _resuming flushes the buffer, any trailing tool hint suffix
is removed so it doesn't persist into the next streaming segment.
3. When final _stream_end closes the card, tool hint suffix is
cleaned from the text before the final card update.
Adds 3 regression tests covering all three scenarios.

Two improvements to Feishu streaming card experience:
1. Handle _resuming in send_delta: when a mid-turn _stream_end arrives
with resuming=True (tool call between segments), flush current text
to the card but keep the buffer alive so subsequent segments append
to the same card instead of creating a new one.
2. Inline tool hints into streaming cards: when a tool hint arrives
while a streaming card is active, append it to the card content
(e.g. "🔧 web_fetch(...)") instead of sending a separate card.
The hint is automatically stripped when the next delta arrives.
