feat(skills): document webflow apps commands

[agustinchiarotto]

Summary

Documents the canonical webflow apps namespace in the Webflow Cloud CLI skill (plugins/webflow-skills/skills/webflow-cloud-command/SKILL.md) and refreshes stale cloud-namespace content. Command surface mirrors apps.ts / registerAppCommands.ts on webflow-cli main.

• New "Managing apps" section — apps list / get / domains, environments list, deployments list / get (with the starting|building|deploying|success|failed|canceled|unstaged status enum, deploying = build-done/deploy-running, pollable-but-no---watch), logs build / runtime (--since / --q / --limit / --cursor, no --level), env-vars list / set / delete / import, and update / delete. Each has a --json example, --fields defaults, the appId/envId resolver precedence, and the --no-input machine-readable missingFlag contract. Read commands derive the workspace server-side (no --workspace-id).
• Canonical vs deprecated — apps init / apps deploy and --app-name / --app-id presented as canonical; cloud init / deploy / create and --project-name / --project-id marked as deprecated (but working) aliases.
• Config/detection — cloud.app_id (legacy cloud.project_id still read as fallback), env vars, and the CLD-1960 resolver precedence table.
• Scaffold ref note corrected (Astro v2 + astro7 betaRef, Next.js v1).

⚠️ Do not merge until CLD-2201 ships

These apps commands only reach stable @latest once the beta gate (if (isBetaBuild()) initApps(program) in cli/webflow.ts) is removed. Hold this PR until that gate removal / prod release lands.

Notes for reviewers

• apps update / apps delete are documented as stable, but the source keeps them behind a second, independent isBetaBuild() gate inside apps.ts that CLD-2201 does not remove. As written, the docs describe two commands that won't exist in @latest until they're separately promoted. Flagging explicitly — may need a follow-up (either gate them in the docs or promote the commands).
• Env var for the environment ID is documented as WEBFLOW_APP_ENVIRONMENT_ID (the actual name in resolveResourceId.ts).
• cloud list is documented as the scaffold-template lister (distinct from apps list), since the code keeps create/list only under the cloud namespace.
• File is now ~1091 lines, over the 500-line CONTRIBUTING guideline. Not split in this PR — a future split may be warranted.

Test plan

• CI structural checks pass (frontmatter name: / description: present)
• Cross-check documented flags/commands against webflow-cli main at release time
• Re-confirm apps update / apps delete gating decision before un-drafting

LGTM, all mentions of standalone, beta and @next are removed as this will be released once CLI hits GA 👍
