Add a ProgressBar demo app

[moersoy]

Companion to geastack/core#69 (ProgressBar, geastack/core#42).

Change

apps/progress-bar, a demo of the @geastack/elements ProgressBar.

• Buttons:
  • step the value within [min, max];
  • push it above max and below min to exercise the bar's own clamping;
  • set a zero range;
  • toggle indeterminate and reducedMotion;
  • resize the bar.
• Fixed bars cover default props, the default range, a fractional value with an empty label, a negative range, an inverted range and NaN. The NaN bar's label prints progressFraction(NaN, 0, 100), because a native build parses a NaN% width as 0.
• core's run-gea-progress-bar-pipeline.sh builds and drives this app.
• The workspace is added to package-lock.json.
• The manifest enables web only and hides the app from launchers, because it has no icons. Following docs/DEVELOPMENT.md, esp32 is false until the app has run on a device.
• docs/EXAMPLE-CATALOG.md lists the app under UI components.

Merge order

The core test needs this app, and core's run-tests.sh picks up the new script automatically, so this PR should merge before the core one. The app depends on @geastack/elements ^0.1.6, which does not export ProgressBar yet. Until an elements release ships it, npm run check passes only against the core branch, not the published package.

Testing

• core's run-gea-progress-bar-pipeline.sh, run from this checkout against the core branch: exit 0.
• tsc 5.9.3 on a copy of the app with @geastack/core and @geastack/elements linked to that branch: exit 0.
• npm ci --dry-run --ignore-scripts on a copy of the workspace manifests and lockfile: exit 0. Without the lockfile entry it fails with "Missing: @geastack/example-progress-bar@0.1.0 from lock file".
• In the browser dev server, before the inverted and NaN bars were added, six Plus taps stop at 100, Over draws a full bar, and Zero range shows "value 40 of 50-50 (zero range)" over an empty bar. Not run on a device or in the WASM simulator.

Summary by CodeRabbit

• New Features
  • Added an interactive progress bar demo with controls for adjusting its value, range, width, motion, and busy state.
  • Added examples showing default, fractional, negative, inverted, zero-width, and invalid-value cases.
  • Added the progress bar demo to the examples catalog.

📝 Walkthrough

This change adds a progress-bar example with interactive controls and static cases for default, fractional, negative-range, inverted-range, and NaN inputs. It also adds the example’s app setup, styling, TypeScript configuration, and catalog entry.

Changes: Progress bar demo

Layer / File(s)	Summary
Progress state and display apps/progress-bar/stores/DemoStore.ts, apps/progress-bar/components/App.tsx, apps/progress-bar/styles.css	DemoStore holds progress and display state, provides update and toggle methods, and supplies a label. App connects that state to an interactive ProgressBar and renders static input cases. The stylesheet sets the page and demo layout.
Example app integration apps/progress-bar/index.tsx, apps/progress-bar/package.json, apps/progress-bar/env.d.ts, apps/progress-bar/tsconfig.json, docs/EXAMPLE-CATALOG.md	The entry point mounts App and imports its stylesheet. Package and TypeScript configuration and the CSS module declaration are added. The example catalog lists progress-bar.

Merge Risk: 🔵 Low · up to 8d99e

The new progress-bar demo will not type-check from a fresh install until an elements release exports ProgressBar. Existing apps are unaffected. Coordinate the release before treating the demo as independently buildable.

Make the declared elements dependency capable of building this app.

The published @geastack/elements package allowed by ^0.1.6 does not export ProgressBar. A fresh workspace install therefore cannot pass npm run check without linking the companion core branch. Coordinate the elements release and update this dependency before treating the app as independently buildable. (github.com)
