docs: address #1674 review — fix broken link + list rendering

- Root README no longer links to docs/mcp-server-configuration.md (not yet
  ported to v2); keep only the mcp-app-review.md pointer (review #3).
- Collapse the Local-fixture parenthetical onto one line so prettier no longer
  renders '- resource preset …' as a mid-sentence bullet (review #5).

Findings #1/#2 (documents unmerged #1576/#1577/#1665 behavior) and #4 (the
web-README #deep-link-auto-connect anchor) resolve in the Wave 4 rollup, which
lands this doc together with those code PRs — the reviewer noted the same.
