Add the required README sections (closes #75)

Policy names five README sections that were missing or misnamed.

The Description first line now names the project, purpose, category,
WTFPL license, and author. A new Getting Started section gives a
copy-pasteable build-from-source block and gen/check/fetch usage; every
command was run against a built binary. Problem Statement and Proposed
Solution are consolidated under a new Rationale heading, keeping the
prose rather than duplicating it. A new Design section documents the
package layout: mfer/ library, internal/cli commands, internal/log and
internal/bork support, cmd/mfer entrypoint, and the committed protobuf
code. Authors is renamed Author with the canonical link.

Getting Started uses go build because the make build target invokes
protoc, which script/bootstrap does not install.

+# Getting Started
+
+`mfer` builds from source with a Go 1.23+ toolchain. The generated protobuf code
+is committed, so no `protoc` toolchain is required:
+
+```sh
+git clone https://git.eeqj.de/sneak/mfer.git
+cd mfer
+go build -o bin/mfer ./cmd/mfer
+```
+
+Generate a manifest for a directory tree, verify it later, and fetch a published
+tree by URL:
+
+```sh
+# Write .index.mf describing every file under the current directory.
+bin/mfer gen .
+
+# Verify the files on disk against the manifest. Exits nonzero if any file
+# is missing or corrupted.
+bin/mfer check .index.mf
+
+# Download and cryptographically verify a tree published over HTTP: mfer
+# fetches <url>/index.mf, then downloads every file it lists.
+bin/mfer fetch https://example.com/tree/
+```
+
+Run `bin/mfer help` for the full command list, or `bin/mfer <command> --help`
+for a single command's options.

+# Design
+
+The repository is split into a reusable library and a thin command-line wrapper
+around it.
+
+- `mfer/` is the reusable library and the heart of the project: it defines the
+  manifest format and implements building, scanning, checking, serialization,
+  and signing. The protobuf schema is `mfer/mf.proto`, and the generated code it
+  produces (`mfer/mf.pb.go`) is committed alongside it so the library builds
+  with `go get` and needs no `protoc` toolchain.
+- `internal/cli/` holds the command implementations — `gen`, `check`, `freshen`,
+  `export`, `list`, and `fetch` — that wire the library to the command-line
+  interface.
+- `internal/log/` provides the logging used across the commands.
+- `internal/bork/` provides error-handling support.
+- `cmd/mfer/` is the entrypoint: its `main` package assembles the pieces above
+  into the `mfer` binary.
+
+Everything under `internal/` is private to this repository; only the `mfer/`
+package is intended for import by other software.
