ci(probe): temporary image build probe, not for main

The Dockerfile, .devcontainer and .cnb.yml named Rust 1.88, below the 1.89
workspace floor, and worked only because rustup fetched the toolchain named by
rust-toolchain.toml inside the image. They now name 1.100.0 (tags
rust:1.100.0-slim-bookworm and rust:1.100.0-bookworm return 200 on Docker Hub),
matching the pin RU-01 puts in rust-toolchain.toml so no second toolchain
downloads during the build.

Checks: release-workflows.test.js green (11 event cases, 13 hermetic checks).

 ## 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.
