docs: full prose sync for zig-lsp registration

Bump plugin-count mentions across docs and site spec; add zig-lsp to
the inline plugin-repos list in ARCHITECTURE.md; rewrite the
agent-coverage parenthetical in reference/AGENTS.md to call out
zig-lsp as config-only (no commands or agents).

ORG_ARCHITECTURE.md milestone records ('All 19 plugins extracted',
'sync pipeline extended to 19 repos', '#250 - all 19 plugins
extracted') are deliberately preserved at 19 - those are historical
extraction milestones, and zig-lsp was born standalone, not extracted.
A new 'Post-extraction additions' block notes zig-lsp's registration
and the open agent-core sync wire-up.

site/index.html tab UI is intentionally not touched: that section is
keyed on slash commands ('20 Commands. One Toolkit.'), not plugins.
zig-lsp ships zero commands, so adding a tab would lie about the
plugin's surface. Plugin count is reflected in the stats counter,
hero badge, meta tags, and skills heading - all already bumped.

Files:
- AGENTS.md: 47 agents 'across 19 plugins' -> 'across 20 plugins
  (zig-lsp ships as config-only)'
- README.md: 2 prose mentions 19 -> 20
- docs/ARCHITECTURE.md: 'All 19 plugins are now standalone' -> 20;
  zig-lsp added to the inline plugin-repos list; 'sync pipeline -
  19 repos' -> 20
- docs/reference/AGENTS.md: agent-coverage parenthetical rewritten
- docs/ORG_ARCHITECTURE.md: 3 milestone records preserved at 19;
  new 'Post-extraction additions' block with zig-lsp entries
- site/ux-spec.md: 6 mentions in spec text and meta strings 19 -> 20

Each plugin lives in its own standalone repo under the [agent-sh](https://github.com/agent-sh) org. agentsys is the marketplace and installer that ties them together.
 
 Each agent has a single responsibility, a specific model assignment, and defined inputs/outputs. Pipelines enforce phase gates so agents can't skip steps. State persists across sessions so work survives interruptions.
