Untrack design_system + finish the SVG move + README fixes

design_system/
- `git rm --cached -r design_system/` so the 23 tracked files are
  removed from the repo's index but stay on disk for local
  reference. Anyone cloning will no longer pull this folder; it's
  been gitignored too.
- Added a `design_system/` rule to `.gitignore` so future
  `git add -A` invocations skip it.

SVG move
- Staged the rename `docs/job-agent-architecture.svg` →
  `docs/images/job-agent-architecture.svg` that was sitting as
  uncommitted in the working tree (the SVG file got moved into
  docs/images/ alongside the other image assets).
- Updated the README's `![Architecture overview]` link to point
  at the new path. The README revision in d638fec missed this —
  it would have rendered a broken image once pulled.

README — small markdown fix
- The "Output" comparison table separator had three dash-blocks
  (|---|---|---|) but the header + body rows have only two
  cells, after the modern_resume_render entry was dropped.
  Trimmed the separator to two blocks (|---|---|) so the table
  renders cleanly on GitHub.
