feat: group tool calls per turn + session entity graph in chat rail
Some checks failed
ci / build-test (push) Has been cancelled
ci / docker-build (push) Has been cancelled

Two chat UX changes (share Chat.svelte, committed together).

Tool-call grouping (ToolCallGroup.svelte):
- Replaced the one-<details>-per-tool-call list with a single
  collapsible group per assistant turn, headed by tool count + a
  name preview and a status icon (spinning wrench in progress, check
  done, X on error).
- The group auto-collapses the instant its turn finishes streaming, so
  a completed round shows as one compact pill; historical/loaded turns
  start collapsed. The auto-collapse fires once at the streaming→done
  transition, leaving manual toggles alone afterward.

Session graph rail (SessionGraph.svelte) — replaces the old
ContextRail (fleet health / pending approvals / live events), which is
deleted:
- A force-directed graph that starts empty (animated constellation
  empty state) and grows as the conversation references entities.
  Slugs are extracted from message text and tool *arguments* only —
  never bulk result rows, so a single get_health_summary doesn't dump
  all 168 entities — then validated against the backend via fetchGraph
  (cached) with check/execution probe entities excluded. Nodes are
  colored by health; edges appear once both endpoints are present.
- Clicking a node highlights it and its neighbors and opens an inline
  detail panel below: slug/type/state, health + freshness, top
  attributes, in-graph relations (clickable to hop), and a Full detail
  button opening the entity sheet.
- The rail is resizable via a drag handle (260–620px, persisted to
  localStorage). The header's global fleet-health dots are unchanged;
  only the right-rail content was replaced.

Risk: reversible_low (UI-only). The slug extractor is scoped to
focused mentions by design; edges may be slightly incomplete since
only root-fetched entities contribute edges, which is acceptable for a
session overview.

Verification: verified in the browser preview — loading a real session
built a 4-node graph (hubris/caddy/netbird-vps/strong) with the
hubris→caddy relationship edge; clicking hubris showed
"proxmox-host · active · healthy · checked 40s ago" with attributes and
relations; dragging the handle resized 320→440px and persisted; a
34-tool historical turn renders as one collapsed pill that expands on
click. tsc clean.
