Add Cloud Agent development environment

[mrnugget]

Summary

Adds a Cursor Cloud Agent development environment for the monkeylang.org Hugo site so future agents can build and preview the site out of the box. This is a repo-managed environment: the committed .cursor/environment.json is the highest-precedence config and takes effect automatically once merged.

The site is a Hugo Extended project (it compiles Bootstrap SCSS via toCSS/libsass in layouts/_default/baseof.html) pinned to Hugo 0.157.0 in netlify.toml. The default Cloud Agent image ships Go and Node but not Hugo, so the environment installs the matching Hugo Extended release.

Changes

• .cursor/install.sh — idempotent install script that installs Hugo Extended 0.157.0 (kept in sync with the HUGO_VERSION pin in netlify.toml), skips the download when the correct version is already present, and runs hugo --gc --minify so setup fails loudly on a broken checkout.
• .cursor/environment.json — runs the install script, exposes port 1313, and starts hugo serve -D --disableFastRender as a persistent terminal (the dev command documented in README.md).
• .gitignore — ignore Hugo's .hugo_build.lock, which the dev server creates.

Validation

Validated end-to-end on the current VM and on a fresh Cloud Agent booted from a draft build of this branch (bld-20260814-01fb285d-...):

Check	Result
Hugo Extended version	0.157.0+extended
Production build (hugo --gc --minify)	5 pages built, SCSS compiled
Install script idempotence	Passes on both fresh-download and already-installed paths
Dev server (hugo serve)	HTTP 200 at localhost:1313, serves ~98 KB compiled stylesheet, renders all sections
Fresh Cloud Agent (from tested build)	All checks passed

Rendered site served by the environment's dev server:
