fix: durable inflight reload snapshots via localStorage (#367)

Browse Source 
* fix: persist durable inflight reload snapshots

* fix: remove duplicate loadInflightState stub, update CHANGELOG test count

The stub added in the previous review branch is superseded by the author's
real localStorage-backed implementation in the cherry-picked commit 36051c0.
Remove the duplicate. Update CHANGELOG to 961 tests and document the durable
inflight state feature.

## [v0.50.21] Live reasoning, tool progress, and in-flight session recovery (PR #367)
- **Durable inflight reload recovery** (`static/ui.js`, `static/messages.js`): `saveInflightState` / `loadInflightState` / `clearInflightState` backed by `localStorage` (`hermes-webui-inflight-state` key, per-session, 10-minute TTL). Snapshots are saved on every token, tool event, and tool completion, and cleared when the run ends/errors/cancels. On a full page reload with an active stream, `loadSession()` hydrates from the snapshot before calling `attachLiveStream(..., {reconnecting:true})` — partial messages, live tool cards, and reasoning text all survive the reload.
- **Live reasoning cards during streaming** (`static/ui.js`, `static/messages.js`): The generic thinking spinner now upgrades to a live reasoning card when the backend streams reasoning text. `_thinkingMarkup(text)` and `updateThinking(text)` centralize the markup so the spinner and card share the same DOM slot. Works with models that emit reasoning via the agent's `reasoning_callback` or `tool_progress_callback`.
- **`tool_complete` SSE events** (`api/streaming.py`, `static/messages.js`): Tool progress callback now accepts the current agent signature `on_tool(*cb_args, **cb_kwargs)` — handles both the old 3-arg `(name, preview, args)` form and the new 4-arg `(event_type, name, preview, args)` form. `tool.completed` events transition live tool cards from running to done cleanly.
- **In-flight session state stable across switches** (`static/messages.js`, `static/sessions.js`): `attachLiveStream` refactored out of `send()` into a standalone function; partial assistant text mirrored into `INFLIGHT` state on every token; `data-live-assistant` DOM anchor preserved across `renderMessages()` calls so switching away and back doesn't lose or duplicate live output.

- **Session-scoped message queue** (`static/ui.js`, `static/messages.js`): Global `MSG_QUEUE` replaced with `SESSION_QUEUES` keyed by session ID. Queued follow-up messages are associated with the session they were typed in and only drained when that session becomes idle — no cross-session bleed.
- **`newSession()` idle reset** (`static/sessions.js`): Sets `S.busy=false`, `S.activeStreamId=null`, clears the cancel button, resets composer status — ensures a fresh chat is immediately usable even if another session's stream is still running.
- **Todos survive session reload** (`static/panels.js`): `loadTodos()` now reads from `S.session.messages` (raw, includes tool-role messages) rather than `S.messages` (filtered display), so todo state reconstructed from tool outputs survives reloads.
