docs: the README front page shows the tool and counts it right

The front page had to do two jobs it was not doing: make a visitor want the
download, and be true. It is now ordered badges, one paragraph, the star ask,
what it can do, two moving pictures, then the table of contents.

Measured before writing, because the README is the shop window:

  * All five badge endpoints answer, with real values - CI passing, release
    v0.2.0, downloads 82, GPLv3, platform. The green Download badge and the Go
    badge came off, and the three platform badges lost their links because a
    platform is a fact and not a place to go.

  * Anchors come from GitHub's own renderer, read back from this repository
    rather than worked out from the heading text. That found a trap worth
    keeping: an emoji carrying a variation selector leaves the selector behind
    in the slug, so "Commands" answers to an anchor beginning with an
    invisible U+FE0F while "Formats it generates" answers to a plain hyphen.
    A link written the way it looks on screen would be dead and would look
    right. Nineteen of the twenty entries are confirmed against that render.

Four sentences said things that stopped being true. The tool registers twenty
one formats, the intro claimed twenty and the feature table said twenty. TIFF
shipped and the question about what comes next still listed it. The manifest
sample quoted version 0.1.0. And the first sentence ended with two full stops.

The feature table is gone rather than duplicated: the same eight rows read
better as a list, and four more went in that the table never carried - the
boundary set, ten thousand files at once, an archive with real contents, and
per format settings. Every one of them is something the seven browser based
generators measured in August do not do.

window.png stays in the tree. The README no longer shows it, but the website
does, and a guard compares the two copies byte for byte.

+Testing Files Generator is a tool for QA engineers and developers who need real
+files to test against - an upload form, a parser, anything that takes a file and
+has an opinion about it. You pick one of its 21 formats and the size you want,
+and you get **exactly that**: ask for a 10 MB PDF and you get a PDF that a reader
+will open, at 10 MB to the byte. Every run also leaves a manifest saying **what
+your system should do with each file**, which is the part other generators leave
+to you. It runs from a desktop window or a command line built for CI, never
+touches the network, and works on Windows, macOS and Linux.

+## ⚡ What it can do
+
+- **Hit an exact size, to the byte** - ask for 10485761 bytes and get exactly
+  that, never a silently rounded file.
+- **Write 21 real formats** - a generated PNG opens in an image viewer, a DOCX
+  opens in Word, a ZIP extracts. Not padded zeros with an extension.
+- **Say what should happen to each file** - the manifest carries an expected
+  outcome, so your test reads the assertion instead of you writing it out.
+- **Repeat itself byte for byte** - same recipe and seed, same bytes, on any
+  machine. Commit a small recipe instead of large binary fixtures.
+- **Build a boundary set in one command** - one byte under a limit, the limit
+  itself, one byte over. That is where off by one errors live.
+- **Produce ten thousand files at once** - one command, one manifest, and sizes
+  drawn from the seed.
+- **Fill an archive for real** - a ZIP that holds 200 documents, not a stub with
+  the right extension.
+- **Take settings per format** - image dimensions, JPEG quality, PDF pages,
+  spreadsheet rows and columns.
+- **Fit into CI** - an exit code for every ending, machine readable output, and
+  nothing on standard output when a run fails.
+- **Clean up after itself** - `verify` tells you nothing moved, `cleanup`
+  removes exactly what it wrote and nothing else.
+- **Work completely offline** - no account, no cloud, no telemetry, no update
+  check. The command line binary has no network stack compiled into it at all.
+- **Cost nothing and stay out of your way** - GPL-3.0, and the files you
+  generate are yours with no strings attached.
