docs(readme): remove em dashes and drop project status table

[joalves]

Summary

• Replace every em dash in README.md with punctuation that fits the sentence (comma, colon, or period)
• Remove the "Project status" heading, blockquote, and Area/Status table
• The install snippet that sat under that heading now has its own ## Install heading so the document still flows

Docs only; no code or behavior changes.

🤖 Generated with Claude Code (via agent-run, /start-feature)

Poem

A rabbit reads the README bright,
Where commas hop in neat delight.
The dashes rest, the words stay clear,
No changed commands or APIs here.
“Thump, thump!” says Bun, “the docs are right!”
