docs(readme): say what the client does, not what it enables

[adnaan]

This README mirrors to /client on the docs site, which now has a written voice — VOICE.md, added in livetemplate/docs#137.

The Overview opened with the product as subject and a verb standing in for the thing it actually does:

The LiveTemplate client enables reactive web applications by efficiently applying tree-based HTML updates from the server. It uses DOM morphing, intelligent static content caching, and WebSocket transport for real-time interactivity.

"enables reactive web applications" is not something the library does; applying updates to the DOM is. Now:

The server sends tree-based HTML updates; this client applies them to the DOM. It morphs the existing nodes rather than replacing them, keeps the static parts of the page cached, and carries actions and updates over a WebSocket.

Also ## How It Works → ## How it works, matching every other heading in the file.

Two lines total. No feature list, install steps, or API docs touched.

Verification

0 .ts/.js files touched. The repo's pre-commit hook ran lint, the full jest suite (824 passed, 39 suites) and the browser build — all green.

Reviewed — this is a clean, docs-only wording fix (2 lines, no code touched).

• Overview rewrite is accurate: it correctly describes what the client does (applies tree updates via DOM morphing, static caching, WebSocket transport) rather than the vague "enables reactive web applications" framing.
• ## How It Works → ## How it works is consistent — checked, every other heading in the file already uses sentence case.

No bugs, security issues, or quality concerns. LGTM.
