Updated local setup docs for host-based Ghost pnpm dev

[louisghost]

Summary

• Document the host-based Ghost pnpm dev setup: funnel Ghost's development port (2368 / worktree GHOST_DEV_PORT) instead of nginx on port 80.
• Replace config.local.json url guidance with the url= env override (and optional ACTIVITYPUB_PROXY_TARGET) that pnpm dev actually uses.
• Align AGENTS.md / CLAUDE.md with the same Tailscale + public URL flow.

Test plan

• Follow the updated README setup against a current Ghost checkout
• Confirm tailscale funnel --bg 2368 + url=https://…/ pnpm dev reaches the reader when ActivityPub is running on 8080

Walkthrough

The local-development instructions replace nginx on port 80 with Ghost’s pnpm dev proxy to the ActivityPub service on port 8080. They describe exposing Ghost’s development port through Tailscale Funnel and starting Ghost with a public URL override. The instructions also note proxy-target differences between Ghost checkouts and that Ghost must be restarted to apply the override.

Merge Risk: 🔵 Low · up to 91104

Worktree users may expose the wrong port and fail to reach Ghost through the public URL. The issue is limited to local setup and can be worked around by using the configured port.

Before / after behavior

• observed — Modified behavior in AGENTS.md: The local-services instructions replace nginx’s port-80 proxy and funneling port 80 with direct app access on port 8080. They document Ghost proxying ActivityPub routes to 127.0.0.1:8080, an explicit proxy target for older Ghost checkouts, and funneling Ghost’s development port (2368 or GHOST_DEV_PORT) before starting Ghost with the tailnet URL.
• observed — Modified behavior in README.md: The proxy description changes from nginx forwarding ActivityPub paths to a Ghost pnpm dev host-based proxy for those paths, with a default target of 127.0.0.1:8080. The setup replaces exposing nginx on port 80 and configuring Ghost through config.local.json with starting the ActivityPub service, exposing Ghost’s development port 2368 (or GHOST_DEV_PORT in a worktree), and starting Ghost with a public url= override and ACTIVITYPUB_PROXY_TARGET. It clarifies that pnpm dev sets url, recent Ghost checkouts default the proxy target while older ones may require it explicitly, and an already-running Ghost must be restarted.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Use the worktree port in each exposure command.

Both files identify GHOST_DEV_PORT for worktrees but hard-code 2368 in their Funnel commands. README.md also hard-codes 2368 in its ngrok command. When a worktree uses another port, these commands do not expose that worktree's Ghost server.

• README.md#L26-L26: Use the main-checkout port for the main checkout and the worktree's GHOST_DEV_PORT for both Funnel and ngrok.
• AGENTS.md#L45-L45: Use the worktree's GHOST_DEV_PORT in the Funnel command.
