feat(dashnote): add single-file read-only lite companion

Mirrors dashmint-lite / dashproof-lite: zero-build static HTML loading the
Evo SDK from esm.sh. Recent notes (with optional owner filter), get note by
ID, click-to-copy on truncated identifiers.

+- **[public/dashnote-lite.html](public/dashnote-lite.html)** — single-file zero-build companion. Read-only Recent notes (with optional owner filter) + Get-by-ID only, loads `@dashevo/evo-sdk` from `esm.sh`, and ships alongside the React app at `<...>/dashnote/dashnote-lite.html` (Vite copies `public/*` into `dist/`). Intentionally self-contained as a learning reference — don't import app code into it.
 - **[test/](test/)** — Vitest + Testing Library. All test files live in this flat directory and are named after the subject under test (e.g. `NotesWorkspace.test.tsx`, `SessionContext.test.tsx`, `notesCache.test.ts`) — they are **not** co-located next to source files, and the directory is **not** mirrored against `src/`. Default Vitest env is `node`; component tests opt into DOM with a `// @vitest-environment jsdom` pragma at the top of the file.
