chore(engine): drop unused dev-deps, dead one-hit symbols and stale allows (CW-8027 slice 6)

Unused manifest entries (grep-verified, proven with cargo check --tests):
account-cli toml; core dev tokio; runtime dev futures-util; engine dev
cucumber, tiny_http, pretty_assertions, rio-vt, tokio-tungstenite; tui dev
pretty_assertions, rusqlite, schemars, tokio-tungstenite; repl test-support
feature. Cargo.lock regenerated offline (edges only).

Dead symbols with a single hit (the definition): core Thread::set_leaf,
ModelRegistry::is_known_for_other_provider, FleetRoleMap::contains_role,
config MODELS_DEV_API_URL / MODELS_DEV_MODELS_URL / get_raw_string /
OfferingPricing::price_per_million, telemetry NOTICE_HEADLINE,
engine auto_route_usage_source_id, paths legacy_deepseek_home_override, and
the four workflow aliases WorkflowIr/Phase/Task/Role.

Stale allow(dead_code) dropped on SidebarRowAction::PrefillCommand and
set_tail_mode; test-only mode/is_active/is_selecting moved behind cfg(test);
false GPUI sentence removed from palette rgb.rs.

Kept: DEFAULT_GOAL_MAX_STEPS (documented as retained for public runtime API).

 ## Unreleased — 0.2.0
 
+- Add data displays: `DataSparkline`, `DataBars` and `DataTrend` (a braille
+  line chart). The words carry every value; the ink draws in from a caller
+  progress (`MotionStep::drawn`) and is at its end state under reduced or
+  still motion. Bars glide from their previous values.
+- Add `DataDisplay`, the same displays as JSON an agent can send:
+  `DataDisplay::from_json` validates it (finite numbers, at most 1024 points
+  or 24 bars, labels up to 120 characters), `describe` says the same facts as
+  plain text, and `DATA_DISPLAY_SCHEMA` is its tool schema. Try
+  `cargo run --example data`.
+
 - Reexport the shared avatar contract from Codewhale Protocol. Rendering and
   artwork stay in this library. Protocol 0.10.3 registry proof must precede
   this package publication.
