fix(chat): isolate concurrent session events and workspace dialog i18n (#351)

* feat: per-session workspace with folder picker, HERMES_HOME support, esbuild fix

* fix(chat): isolate concurrent session events and workspace dialog i18n

Two user-visible bugs are fixed here:

1. Workspace dialog title showed the raw i18n key 'chat.setWorkspaceTitle' because the key was never added to en.ts / zh.ts. The dialog is opened from ChatPanel.vue but only 'setWorkspace' existed. Add the missing 'setWorkspaceTitle' translation in both locales.

2. With two concurrent runs the assistant text from session A would show up in session B (and vice versa). The /chat-run namespace uses a single shared Socket.IO connection on the client; every startRunViaSocket() call registers its own listeners on the same socket. The server fans events out via 'session:<id>' rooms, but a single socket can be in multiple rooms at once and there was no per-event filtering on the client. Each run's closure captured its own sid and wrote into the wrong session. The server already tags every payload with session_id, so the fix is a guard inside handleEvent() that drops events whose session_id does not match this run's body.session_id. Untagged events are still accepted for backwards compatibility.

3. Also fix a related crash where setting a workspace on a session that had not been persisted yet (no first message sent) threw because the row did not exist. Create the row on demand inside setWorkspace controller.

* fix: upgrade esbuild to 0.27+ for vite 8 compatibility
