Description

When the lossless-claw plugin is active, the webchat UI flickers (messages disappear and reappear) after every message send/receive. This makes the webchat nearly unusable.

Root Cause

1. lossless-claw fires session.message events when it ingests messages into its database
2. The webchat client's jC handler listens for these events and calls Qf (history fetch)
3. Qf sets chatLoading=true before fetching, which triggers a loading state in the UI
4. This causes messages to visually disappear during the fetch, then reappear when it completes
5. With lossless-claw firing multiple events per turn, this creates rapid flicker

Steps to Reproduce

1. Enable lossless-claw plugin
2. Open webchat UI
3. Send a message
4. Observe messages flicker (disappear/reappear) after send

Suggested Fix

Either:

1. Debounce the session.message handler — wait 500ms after last event before fetching
2. Don't set chatLoading=true for incremental refreshes — only show loading state on initial load
3. Skip loading state entirely in jC pathway — call a variant of Qf that doesn't set chatLoading

Workaround

Patch index-CsLHusjn.js to make jC a no-op:

// Original:
function jC(e,t){let n=t?.sessionKey?.trim();!n||n!==e.sessionKey||Qf(e)}

// Patched:
function jC(e,t){return}

This disables session.message refresh entirely. History still loads on page load and run completion.
