fix: prevent trace platform header wrapping

 - Remove the outer gray trace card and tinted list shell, using a flat tab layout with toolbar/table separators in both themes.
 - Top hint and separate recording switch → a toolbar Start/Pause/Connecting button. Filters, recording, and refresh share gray icon-and-text styling and 36px input height; search fills available width and includes the message count in its placeholder.
 - Use Vuetify datatable with native rows, typography, spacing, and hover styling for the trace list; customize individual cells while retaining fixed headers, stable trace row IDs, keyboard activation, and explicit detail selection without adding pagination or automatic selection.
+- Shorten the Chinese duration column label and prevent the platform column header from wrapping with a minimum width.

 The trace tab has no outer gray card; its toolbar and list sit directly on the page with only the necessary separators. The former hint and switch are replaced by a toolbar button showing Pause (enabled and connected), Connecting (enabled but disconnected), or Start (disabled). Filters, recording, and refresh use matching light-gray icon-and-text buttons sharing the input's background color, all 36px high. Search fills the remaining width, pushing actions to the right. Its placeholder includes the message count instead of a separate counter. Click to pause or resume. Updates show loading and prevent repeated clicks; failures preserve the previous state and display an error. Pausing retains the list and open details in both themes.
 
-The `Trace` tab shows message execution chains: receipt, plugin handlers, Agent requests, responses, and completion. It opens as a full-width Vuetify datatable with columns ordered as status chip, platform logo, timestamp, duration, message, UMO, sender, and Spans. Headers, row height, and spacing use Vuetify defaults; only cell content such as status, platform icons, and messages is customized. Duration updates while execution is active. Click a row to open its timeline details on the right; use the close button or Escape to return to the list. History loading, incoming records, and filtering never automatically open another trace. Scroll horizontally on narrow screens. Spans counts timeline nodes after pairing start/end records; collapsing groups does not reduce it. The search placeholder counts message traces only. Open `Filters` next to search to select `Has errors`, `Has model calls`, and `Has plugin calls`. Multiple selections require all conditions and can be combined with search. No selection shows all traces; `Reset` clears selections, and closing the sidebar preserves them. This sidebar replaces the former `All / Errors / Agent / Plugins` single-select tabs. Use the toolbar recording button to enable or disable trace recording.

 Session aliases replace raw UMOs when available; hover over the dotted underline to see the full UMO. Plugins use their display name when available; hover to see the plugin ID. Handler names, event types, and duration are also shown. Plugin handler nodes use the plugin logo when available and the plugin card's default blue star icon if it is missing or fails to load. Titles show the category in parentheses, matching the plugin detail page: command/command group, event listener, event hook, or LLM tool.
