Sub-area #3 of the v0.6.6 UI redesign (issue #121).
Introduces `crates/tui/src/tui/widgets/tool_card.rs` — a small,
self-contained vocabulary module that owns:
- `ToolFamily` enum (Read / Patch / Run / Find / Delegate / Fanout /
Think / Generic) and the verb-glyph + label per family
(▷ read, ◆ patch, ▶ run, ⌕ find, ◐ delegate, ⋮⋮ fanout, … think)
- `tool_family_for_title` — maps the legacy header titles
(`"Shell"`, `"Patch"`, `"Workspace"`, `"Search"`, `"Diff"`, `"Image"`)
to a family, so existing call sites pick up the new glyph without
re-architecture
- `tool_family_for_name` — maps actual tool names
(`agent_spawn`, `apply_patch`, etc.) for `GenericToolCell`, which
shares the catch-all `"Tool"` title across every model-facing tool
- `CardRail` + `rail_glyph` — the `╭ │ ╰` rail vocabulary, declared
here so any future per-card refactor has the matching glyphs
Wires the verb glyph + label into `render_tool_header` and adds a
`render_tool_header_with_family` overload so `GenericToolCell` can
route by tool name rather than the generic title. The header now reads
`<spinner> <verb-glyph> <verb> <state>` instead of
`<spinner> <Title-Case-Word> <state>`.
Existing parity tests for ExecCell / PlanUpdate are updated to assert
against the new header structure (verb + glyph) — the colour wiring is
unchanged. New tests pin the verb-glyph format end-to-end:
`agent_spawn` → `◐ delegate`, exec → `▶ run`.
Spinner cadence (TOOL_STATUS_SYMBOL_MS = 720 ms) is unchanged — the
spec already matched.
Deferred to a follow-up: full per-card rail (`╭ │ ╰`) refactor that
threads `CardRail` through every cell render path. The vocabulary is
in place; the layout pass is the next bite.
