fix: restore guix.scm identity and licence (squisher-corpus clobber is live on main) (#143)

## Urgent: a licence misstatement is currently live on the public
default branch

`guix.scm` on `main` declares this repository as **`squisher-corpus`**
under **`PMPL-1.0-or-later`**. It is neither — this is `maa-framework`,
MPL-2.0.

```diff
-  (name "squisher-corpus")                          +  (name "maa-framework")
-  (synopsis "squisher-corpus")                      +  (synopsis "maa-framework")
-  (home-page ".../hyperpolymath/squisher-corpus")   +  (home-page ".../hyperpolymath/maa-framework")
-  "PMPL-1.0-or-later"                               +  "MPL-2.0"
```

Restored verbatim from `7b6a293`, the last commit where it was correct.
**One file, six lines.**

## How it got here

An automated sweep on **2026-07-26 ~16:00 BST** copied
`hyper-repos/squisher-corpus/guix.scm` **byte-for-byte** into a large
number of estate repos rather than generating one per repo. The sweep's
own commit message names the bug: `chore: update guix.scm from
squisher-corpus`.

In this repo it first appeared as local commit `f06ea94`, which was
dropped on 2026-07-27 — `origin/main` was still clean at `7b6a293` at
that point.

**It reached `origin/main` anyway, via #142** (`fix(ci): repoint
codeql-action at a SHA that exists`), a CI fix that swept up an
unrelated dirty working-tree file. This is the `commit -a` on a dirty
tree hazard.

## Why this matters beyond cosmetics

1. **Identity** — the package advertises the wrong name and home-page.
2. **Licence** — MPL-2.0 was replaced with `PMPL-1.0-or-later` on a
public default branch.

`absolute-zero/.claude/CLAUDE.md` lists `PMPL-1.0` / `PMPL-1.0-or-later`
as **BANNED** ("License: MPL-2.0 only"), so this is a policy violation
as well as a factual error.

## Scope check

`.editorconfig` and `aletheia/.editorconfig` on `main` are **clean** —
`guix.scm` is the only affected file in this repository.

## Wider context (not fixed here)

A scan of **279 repos against their ORIGIN refs** finds **65 clobbered
`guix.scm` files across 52 repositories**, including `standards`. An
earlier scan against local working trees reported only 9 — it
undercounted roughly 6× because repos whose local checkout lags origin
were invisible to it. Tracked separately; this PR fixes only this
repository.
