What

Adds a new "Project Architecture" section to README.md, briefly explaining
the purpose of crates/, tests/, examples/, docs/, benches/, and
scripts/, plus a simple repository tree diagram.

Why

The README currently covers vision, goals, and tech stack, but gives new
contributors no overview of how the repo is structured, making it harder to
know where to start. Closes #282.

How

Inserted the new section between ## what's coming and ## status, matching
the existing README's lowercase header style and plain bullet formatting.
No code was changed — this is a documentation-only edit.

Checklist

  • cargo test --workspace passes — N/A, no code changed
  • cargo clippy --workspace -- -D warnings passes — N/A, no code changed
  • cargo fmt --all applied — N/A (Markdown file, not applicable, unchanged)
  • CHANGELOG.md updated (if user-facing change) — not applicable, internal docs addition only
  • Benchmarks added or updated (if performance-sensitive path) — N/A, no performance-sensitive code touched

Fence the tree diagram.

As written, this block will render like normal list text, so the tree alignment is likely to break in Markdown. Wrap the diagram in a fenced code block to keep the layout readable.

Match the README’s existing capitalization style.

The new section prose and both headings are lowercase, while the surrounding README uses title-case headings and normally capitalized sentences. Please use Project Architecture, Status, and standard sentence capitalization for consistency.
