Add first-class profile support to the desktop app without app reloads.
- Swap the single live gateway onto a session's profile lazily (spawned on
demand by the Electron backend pool), so one backend serves the active
profile and others stay cold — no OOM with many profiles.
- Aggregate sessions across profiles by reading each profile's state.db
read-only; unified "All profiles" view groups sessions per profile with
per-profile pagination, while the default view stays scoped to one profile.
- Add an Arc-style profile rail at the sidebar foot: a default<->all toggle
pinned left, colored named-profile squares scrolling between, Manage pinned
right. Profile identity is a deterministic per-name color.
- Route profile-scoped REST (config/env/skills/tools/model) to the active
gateway profile and invalidate React Query caches on swap. Single-profile
users never trigger a swap, so their path is unchanged.
Backend:
- web_server: profile-aware active/list endpoints + per-profile session
totals; hermes_state: session_count(exclude_children); main.py: honor
--profile over HERMES_HOME env for pooled backends.
UI primitives:
- Add a position-aware Tip tooltip (instant, themed) as a drop-in for native
title=, and strip redundant tooltips from self-descriptive chrome.
The reconnect and boot paths resolved the WS URL with
`(await getGatewayWsUrl().catch(() => null)) || conn.wsUrl`. For OAuth
gateways the cached conn.wsUrl carries a single-use, ~30s-TTL ticket; the
desktop connection is memoized for the process lifetime, so on reconnect
that ticket is both expired and already consumed. A failed fresh mint
therefore fell back to a guaranteed-dead ticket and surfaced as an opaque
"connection closed", masking the gateway's actionable "session expired,
sign in again" message.
Extract resolveGatewayWsUrl() (with unit tests): in OAuth mode a mint
failure throws a tagged GatewayReauthRequiredError instead of falling back;
token/local modes keep the long-lived-token fallback. Thread that error
through the reconnect path so requestGateway surfaces the reauth message
rather than the generic transport error that triggered the retry.
