Introduce a new `show_tool_calls_in_im` bot setting plus a full overhaul of
how tool calls are surfaced in IM channels:
- Add per-bot setting + migration (0072) and expose through settings API /
handlers / frontend SDK.
- Introduce a `toolCallDroppingStream` wrapper that filters tool_call_* events
when the setting is off, keeping the rest of the stream intact.
- Add a shared `ToolCallPresentation` model (Header / Body blocks / Footer)
with plain and Markdown renderers, and a per-tool formatter registry that
produces rich output (e.g. `web_search` link lists, `list` directory
previews, `exec` stdout/stderr tails) instead of raw JSON dumps.
- High-capability adapters (Telegram, Feishu, Matrix, Slack, Discord) now
flush pre-text and then send ONE tool-call message per call, editing it
in-place from `running` to `completed` / `failed`; mapping from callID to
platform message ID is tracked per stream, with a fallback to a new
message if the edit fails. Low-capability adapters (WeCom, QQ, DingTalk)
keep posting a single final message, but now benefit from the same rich
per-tool formatting.
- Suppress the early duplicate `EventToolCallStart` (from
`sdk.ToolInputStartPart`) so that the SDK's final `StreamToolCallPart`
remains the single source of truth for tool call start, preventing
duplicated "running" bubbles in IM.
- Stop auto-populating `InputSummary` / `ResultSummary` after a per-tool
formatter runs, which previously leaked the raw JSON result as a
fallback footer underneath the formatted body.
Add regression tests for the formatters, the Markdown renderer, the
edit-in-place flow on Telegram/Matrix, and the JSON-leak guard on `list`.
Migrate the imported WeCom adapter to current channel interfaces and stabilize stream delivery by preventing heartbeat/reply ACK timeout regressions and post-final overwrite updates.
