fix: replace removed acp.TerminalHandle with Client terminal methods

[howardpen9]

Summary

• Replace all acp.TerminalHandle usage with the new ACP 0.8 request/response API in tools.py and kaos.py
• create_terminal() now returns CreateTerminalResponse with .terminal_id instead of a TerminalHandle object
• Terminal operations now use Client methods (wait_for_terminal_exit, terminal_output, kill_terminal, release_terminal) with explicit session_id and terminal_id parameters

Root Cause

agent-client-protocol 0.8.0 removed TerminalHandle from the public API (migration guide). Since kimi-cli v1.17+ pins agent-client-protocol==0.8.0, any ACP terminal tool call fails with:

Error running tool: module acp has no attribute TerminalHandle

Changes

src/kimi_cli/acp/tools.py

• terminal: acp.TerminalHandle | None → terminal_id: str | None
• Extract terminal_id from CreateTerminalResponse.terminal_id instead of asserting TerminalHandle
• Call self._acp_conn.wait_for_terminal_exit(session_id, terminal_id) instead of terminal.wait_for_exit()
• Call self._acp_conn.terminal_output(session_id, terminal_id) instead of terminal.current_output()
• Call self._acp_conn.kill_terminal(session_id, terminal_id) instead of terminal.kill()
• Call self._acp_conn.release_terminal(session_id, terminal_id) instead of terminal.release()

src/kimi_cli/acp/kaos.py

• ACPProcess.__init__ now takes client: acp.Client, session_id: str, terminal_id: str instead of terminal: acp.TerminalHandle
• All internal terminal operations updated to use Client methods with explicit IDs

Test plan

• ruff check passes on both changed files
• Run kimi-cli as ACP agent in Zed IDE and execute a shell command (e.g., git log --oneline -6)
• Verify terminal tool call succeeds without TerminalHandle AttributeError

Fixes #1380
