test(canvas): add explicit STATUS_CONFIG shape coverage

STATUS_CONFIG exports 7 status keys (online, offline, paused, degraded,
failed, provisioning, not_configured) with dot/glow/label/bar per entry.
The existing statusDotClass.test.ts covered .dot indirectly but left the
constant's full shape (label, glow, bar) untested. Add a dedicated
design-tokens.test.ts that asserts all keys exist, every entry has the
correct fields, and field values match the known tailwind tokens.

-// agent_card_reconcile.go — server-side repair for the fleet-wide
-// agent-card identity gap.
-//
-// Root cause: the runtime builds its AgentCard from config.name
-// (workspace/main.py:198), and config.name is read from the
-// CP-regenerated /configs/config.yaml whose `name:` field is the raw
-// workspace UUID — NOT the friendly name the operator sees. The friendly
-// name IS captured: POST /workspaces and PATCH /workspaces/:id (the
-// canvas Details tab) write it to the trusted workspaces.name DB column.
-// But /registry/register stores the runtime-supplied card verbatim
-// (registry.go: `agent_card = EXCLUDED.agent_card`), so the stored card
-// served at /.well-known/agent-card.json and returned to peers via
-// agent_card_url ends up with name = UUID, description = "", role = null.
-//
-// Fix shape (deliberately minimal, no contract weakening): when the
-// runtime-supplied card's `name` is empty or equals the workspace UUID
-// (the placeholder the runtime had no better value for), the PLATFORM —
-// not the agent — substitutes the friendly value from the trusted
-// workspaces row. Identity stays platform-controlled: the agent never
-// gains the ability to self-set its own name/role; the platform sources
-// it from the operator-controlled DB column. We only ever FILL gaps
-// (empty / UUID-placeholder); a card that already carries a real
-// friendly name is never downgraded.
-//
-// list_peers / the /registry/:id/peers endpoint already resolve display
-// names from workspaces.name directly (discovery.go / mcp_tools.go
-// `SELECT w.id, w.name, ...`), so peer_name in delivered message tags
-// was already correct — this fix closes the remaining surface: the
-// agent_card blob itself (canvas Agent Card / Skills view, peer
-// agent_card_url fetches, the well-known card).
-//
-// description / role degrade discovery the same way: an empty
-// description and null role give peers nothing to reason about. We
-// default description from the (now reconciled) name when blank and
-// role from workspaces.role when the operator set one.
-
-// reconcileAgentCardIdentity patches identity gaps in a runtime-supplied
-// agent card from the trusted workspace DB row. It returns the
-// (possibly rewritten) card bytes and whether anything changed. On any
-// failure (malformed JSON, nothing to fill) it returns the input bytes
-// unchanged with changed=false so the caller can store them verbatim —
-// this is strictly no-worse-than-before, never a regression.
