Fix CI blockers: changelog format, oxlint, arch-docs

1. changelog.d/1438-workflow-ui-unify.added.md: remove blank lines
   between paragraphs (one continuous fragment entry).

2. MiniFlowchart: remove unused roster parameter from function
   signature and all call sites (lines 261, 516, 957).

3. arch-docs: core/src/client/i18n.js changes are translation keys
   only for Workflow inspector UI ('Select a node to edit',
   'Node settings', 'Tools', 'Inputs and outputs'). No behavior
   change to core-client owned paths.

All 55 tests pass. Patches regenerated.

Docs-not-needed: core/src/client/i18n.js adds i18n keys for Workflow inspector UI only

-**Settings → Workflow graphs** is now canvas-first with a per-node inspector panel. Select a node to edit its system prompt, role, and tools — no more wall of textareas.
