Completes i18n coverage of the conversation surface — the strings the
T-464 migration left as "decorative" English:
- running-indicator verbs (Pondering/Conjuring/… → catalog, Dutch added)
- pane chrome title (primary / secondary N) and banner role
- tool-card titles (Edit → Bewerken) via a tool.name.* key set, with
command/proper-name tools (Bash, Grep, Glob, LS) falling back to the
raw name
- collapser step/edit/agent counters
- the folded-activity ticker (result/error/thinking/image + tool name)
English degrades to the placeholder where a key is absent, so untranslated
or MCP tool names render unchanged. en_us and nl_nl stay at key parity.
