docs(readme): tighten Usage, add visualize/slides to Quick Start

Critical pass on Usage — it described the generators twice (Layer 2 table +
narrative subsections):

- drop the (i) Query & Chat and (iii) Visualize subsections (already in the
  Layer 2 table; depth is in examples/)
- shorten Skill Factory to a flagship blurb + pointer (no walkthrough)
- add the missing deck/slides generator to the Layer 2 table
- fix the Skill Factory anchor link; remove a dead commented-out lint row

Quick Start: add optional visualize + deck (deck noted as needing a theme).

-### (i) 💬 Query & Chat — *ask the wiki*
-
-`openkb query "..."` answers a single question. `openkb chat` is interactive — each turn carries history, so you can dig into a topic without re-typing context. Both use the same underlying wiki and retrieval primitives.
-
-```bash
-openkb query "What does the literature say about attention scaling?"
-
-openkb chat                       # start a new session
-openkb chat --resume              # resume the most recent session
-openkb chat --resume 20260411     # resume by id (unique prefix works)
-openkb chat --list                # list all sessions
-openkb chat --delete <id>         # delete a session
-```
-
-Inside a chat, type `/` to access slash commands (Tab to complete) — `/add`,
-`/skill new`, `/save`, `/lint`, and more. See [`examples/chat/`](examples/chat/)

-The newest generator. `openkb skill new` distills an [agent skill](https://docs.claude.com/en/docs/build-with-claude/skills) from any subset of your wiki, a portable folder that major agents (Claude Code, Codex, etc.) can install and load natively. Drop in a book's worth of papers; out comes a specialist that other agents can call on.

-
-### (iii) 🗺 Visualize — *see the shape of your knowledge*
-
-`openkb visualize` renders the wiki as a single self-contained, offline HTML page with three views of the same knowledge base — a **3D** force graph, an OpenKB-rooted **mind-map**, and a **radial** tree — coloured by type and linked by `[[wikilinks]]`.

-openkb visualize            # build + open output/visualize/graph.html
