docs: add Cursor Cloud environment setup notes

[rrama]

What

Adds a ## Cursor Cloud specific instructions section to AGENTS.md documenting the non-obvious environment setup needed to build/run/test the Snyk CLI in Cursor Cloud.

Why

Cursor Cloud has restricted egress and a specific pre-provisioned toolchain. The notes record durable caveats future agents need:

• Node/npm: /exec-daemon/node is first on PATH but has no npm; use nvm Node 22.22.3 which provides npm 11.12.1 (this repo pins engine-strict=true with npm ^11.12.1).
• Go toolchain pinned to go1.26.5 (auto-download from go.dev is blocked).
• Build with make build BUILD_MODE=public (cliv2-private/ is inaccessible); output binary-releases/snyk-linux.
• convco is installed at /usr/local/bin/convco (required by release-scripts/next-version.sh).
• The prepare-3rd-party-licenses build step downloads Go's LICENSE from the blocked go.dev; a copy is pre-placed at the gitignored cliv2/internal/embedded/_data/licenses/go.dev/LICENSE so the step skips it.
• How to run acceptance tests against the built binary + fake server; some specs need real registries and fail under restricted egress.

Docs-only change.

Verification

• npm ci ✅
• make build BUILD_MODE=public ✅ → binary-releases/snyk-linux --version works
• cd cliv2 && go test ./pkg/... ./internal/... ✅
• npx jest test/jest/unit/lib/formatters ✅ (120 tests)
• Acceptance snyk-test/all-projects.spec.ts against the built binary ✅ (20/20)

	Warnings
⚠️	Since the CLI is unifying on a standard and improved tooling, we're starting to migrate old-style imports and exports to ES6 ones. A file you've modified is using either module.exports or require(). If you can, please update them to ES6 import syntax and export syntax. Files found: AGENTS.md

Superseded by #7050, which now carries the consolidated notes (including the more accurate account of the license-prep workaround: because go-licenses save --force wipes the tree, the Go LICENSE has to be placed after a build, not before). Closing to leave one cloud-setup PR per repo.
