docs: align Skills corrections with the final SEP and website (#147)

The stable Skills page missed the final SEP's Agent Skills compatibility
clause, and its examples used abbreviated hashes and inconsistent byte
sizes. Archived drafts also retained current-sounding source-of-truth
guidance.

This corrects the stable page directly to match already-established
requirements: restores the compatibility clause, shows the resources
capability and server/discover, explains omitted request metadata, and
makes the example manifests and content consistent. It also labels
archived documents as historical and fixes the SEP domain in AGENTS.md.
This is an editorial alignment, not a new extension proposal; #142
remains separate.

Validation: all JSON examples parsed; all 13 manifest entries checked
against sample bytes for SHA-256 and size; the corrected specification
builds with the VitePress publishing site; git diff --check passed.

AI assistance: prepared with Codex.

# Agent Plugins x Skills Over MCP
> **Historical document.** Frozen during development of SEP-2640; statements of current status and requirements below describe that draft-era context. See the [stable specification](../../specification/stable/skills.mdx) for current requirements and the [archive index](README.md) for context.
## Summary
Agent Plugins 1.0 is a portable *packaging* format — a directory with a `plugin.json` manifest whose two component types are Agent Skills (a `skills/` directory) and MCP server configurations (`mcp.json`). It deliberately layers on top of the Agent Skills spec and MCP rather than redefining either, so it is overwhelmingly a **complement** to SEP-2640: the SEP moves skills over the wire at runtime; Agent Plugins moves them onto disk at install time. The two even compose — a plugin's `mcp.json` can point at a server that itself serves skills under the extension.
