feat(blog): add five blogs (#5268)

* feat(blog): add five AI agent articles

Add how-to-create-an-ai-agent, ai-agent-vs-chatbot, ai-agents-vs-rpa, ai-agent-ideas, and best-zapier-alternatives posts.

* fix(blog): correct ai-agent-ideas pronoun and complete zapier TL;DR

Fix 'everyone' -> 'every idea' in ai-agent-ideas intro; add the four missing tools (Power Automate, Pipedream, Relay.app, Integrately) to the best-zapier-alternatives TL;DR so it lists all 10.

* fix(blog): remove HIPAA compliance claims

We are not HIPAA compliant; drop the claim from ai-agents-vs-rpa and best-zapier-alternatives, keeping the SOC2 claim.

* feat(blog): add cover images for new posts, refresh older post covers

- Add cover.jpg for the 5 new AI agent blog posts
- Replace existing cover art for enterprise, mothership, v0-5, multiplayer,
  executor, series-a, and openai-vs-n8n-vs-sim
- Standardize openai-vs-n8n-vs-sim's og image to cover.jpg (was workflow.png)
- Update ogImage frontmatter paths to match

* fix(blog): move new post dates closer to today

Shift the 5 new AI agent posts from June 23-27 to June 27 - July 1,
keeping the same order and 1-day spacing, ending on today's date.

* fix(blog): use current Sim terminology instead of legacy Mothership/Copilot names

Per the constitution language rules, Sim's own natural-language agent
surface is "Chat" and the agent you talk to is "Sim" — not "Mothership"
or "Copilot" (those are prior internal names, still used correctly in
the historical announcement posts but not for new content). Leaves
references to Zapier's and Microsoft's own "Copilot" products as-is
since those name real third-party features.
