v0.7.22 — starter packs, skill search, and an honest wheel size

mcptoon v0.7.22 — starter packs, skill search, and a README both readers can use

Added

• Four starter skill packs. mcptoon install --packs lists them; mcptoon install --pack essentials installs one. Each is a named bundle of MCP tools plus a ready prompt — essentials (files, browser, memory, search), web-research, code-review, docs. The wheel ships the manifest, never the tools: they install from npm/pip only when you ask. Preview with --dry. Two research packs need no API key.
• mcptoon skills search <query> — search the open skills.sh index by what a skill does, then skills add <git-url> the one you pick. Falls back to the local index when offline. mcptoon hosts no marketplace of its own.

Changed

• Both READMEs rewritten around two reader paths — "I just use AI tools" and "I build with MCP / agents" — with a plain-language explanation of the token saving up top, a CLI-vs-proxy rationale, and the third-party evidence promoted. The five directory badges the rewrite had dropped are restored.
• packs.json now ships in the wheel, so built-in packs work from an install and not only a source checkout.

Fixed

• The wheel-size claim was wrong on every surface. README (both languages), DEVELOPERS.md, docs/comparison.md and docs/tiktoken-benchmarks.md said 233KB. It is 227KB — 232,828 bytes, measured against the tree as CI builds it. The old number came from a Windows checkout with CRLF sources and the pre-rewrite README; line endings alone added ~1.4KB inside the archive. The footprint guard now pins 227KB and retires 233KB.
• Three tests asserted one machine's environment and failed in CI. Fixed so they hold on Windows, macOS and Linux, with or without tiktoken. Product behaviour is unchanged.
