docs: replace em dashes and move previous version section higher

Replace all em dashes with regular dashes in README. Move the
"Previous Version" section to right before Quickstart so existing
users find it immediately.

 Archon fixes this. Encode your development process as a workflow. The workflow defines the phases, validation gates, and artifacts. The AI fills in the intelligence at each step, but the structure is deterministic and owned by you.
 
-- **Repeatable** — Same workflow, same sequence, every time. Plan, implement, validate, review, PR.
-- **Isolated** — Every workflow run gets its own git worktree. Run 5 fixes in parallel with no conflicts.
-- **Fire and forget** — Kick off a workflow, go do other work. Come back to a finished PR with review comments.
-- **Composable** — Mix deterministic nodes (bash scripts, tests, git ops) with AI nodes (planning, code generation, review). The AI only runs where it adds value.
-- **Portable** — Define workflows once in `.archon/workflows/`, commit them to your repo. They work the same from CLI, Web UI, Slack, Telegram, or GitHub.

 ## Web UI
 
 Archon includes a web dashboard for chatting with your coding agent, running workflows, and monitoring activity. To start it, ask your coding agent to run the frontend from the Archon repo, or run `bun run dev` from the repo root yourself.
 
-Register a project by clicking **+** next to "Project" in the chat sidebar — enter a GitHub URL or local path. Then start a conversation, invoke workflows, and watch progress in real time.

 **Key pages:**
-- **Chat** — Conversation interface with real-time streaming and tool call visualization
-- **Dashboard** — Mission Control for monitoring running workflows, with filterable history by project, status, and date
-- **Workflow Builder** — Visual drag-and-drop editor for creating DAG workflows with loop nodes
