refactor(using-markitdown): rewrite MCP→CLI, drop Docker section v1.0.1

Replace all mcp__markitdown__convert_to_markdown invocations with the
native `markitdown <path|url>` CLI (v0.1.6, on PATH). Outputs to stdout
or `-o <file>`; sees the full host filesystem, so the Docker bind-mount
caveat (host→container file:// translation, [Errno 2] /c:/Users/...) is
gone and that whole section is removed. Updated the ingest pattern (-o
straight into .wiki/raw/), gotchas table (command-not-found → check
`markitdown --version`), and contrast table header (CLI, not MCP).
Description triggers unchanged. PATCH bump 1.0.0→1.0.1; dist artifact
rebuilt.

Decommissioned the Docker MCP containers: no container is named
`markitdown-mcp` (the server spawns anonymous ones from
markitdown-mcp:latest, 3 had piled up); removed all by image ancestor.
Left mcpServers.markitdown in ~/.claude.json untouched (out of scope) —
flagged as a follow-up in the concept page.
