v2.0.0: TransformPipe, and four conversions

The rename, at transformpipe.com, and four formats in rather than one: HTML, Word, CSV and TSV, and JSON. Each conversion has an address of its own, because "word to markdown" is a thing people type into a search box.

JSON picks a rendering per shape rather than one rule for everything — an array of flat objects becomes a table, an array of scalars a list, an object a heading per nested key, and anything past three levels a fenced block, because a heading at depth seven is not a heading.

In this release

• Four new conversions: HTML, Word (.docx), CSV and TSV, and JSON to Markdown, each at its own address
• An assistant can act on an account through an MCP connector that needs no API key pasted anywhere
• Fifty-six articles, up from twenty, each with a cover the build refuses to ship without
• The blog stopped being sent to everybody who opened the converter — it had been 952 kB of Markdown in the main bundle
• Renamed from M2H to TransformPipe, domain included
