alexmandClaude 88379d152c feat!: one paperspec command with subcommands, help and examples
The six console scripts (paperspec-check, -build, -validate, -load,
-stress, -site) become subcommands of a single `paperspec` command:
paperspec validate, load, check, build, stress and site. `python -m
paperspec COMMAND` runs the same thing.

- paperspec/cli/main.py builds the whole parser, apart from the commands,
  so `paperspec --help` and `paperspec COMMAND --help` work without a
  checkout or the tools extra; a command's module is imported only when
  it runs.
- `paperspec` with no command prints the overview: what each command does,
  examples, and which work anywhere (validate, load) and which need a
  checkout (check, build, stress, site). Each command's help has a
  description with advice, and worked examples; a misspelled command gets
  a suggestion (argparse suggest_on_error); `--version` prints the version
  and the pinned Unicode version.
- Each command module exposes run(args) and returns the exit status.
  Arguments that parse but do not fit together raise UsageError, which
  prints the command's usage and exits 2: load now also refuses
  --built-from or --store without --bundle.
- The failure messages say what to do: install paperspec[tools], clone the
  repository, rerun stress with the printed seed, or run paperspec build
  when the rebuild check differs. check and stress say how many failures
  they did not list.
- check runs the rebuild as `python -m paperspec build`.
- pyproject installs one script, `paperspec`; the pixi tasks and the docs
  use the subcommands.

pixi run check passes (run here as `python -m paperspec check` with src/ on
the path); the rebuild is byte-identical. pixi.lock still needs
`pixi lock`.

# Fixture sources
Each source describes a document as a converter first read it, mistakes included, in a shorthand that `paperspec build` expands.
The build mints IDs, applies the listed corrections, lays out synthetic geometry, signs the listed receipts and writes the package.
The shorthand is tooling, not a format.
| Shorthand | Becomes |
| --- | --- |
| `{"p": [...]}` | A paragraph of the listed sentences. |
| `{"s": [...]}` | A sentence; a string part is a text run. |
| `{"sup": t}`, `{"sub": t}`, `{"em": t}` | A styled text run. |
| `{"m": src}`, `{"t": src}` | A TeX or Typst math run. |
| `{"cite": [...], "text": t}`, `{"xref": target, "text": t}`, `{"fn": name, "text": t}` | Citation, cross-reference and footnote-mark runs. |
| `{"eq": {...}}` | A display equation inside the sentence. |
| `{"row": [...]}`, `{"c": [...]}` | A table row, and a cell with `role`, `rowspan`, `colspan` and `col`. |
| `"name": "@x"` | A local name, replaced by the minted ID; `ext:<doc>:@x` names a node of another source. |
| `"page": n` | The page the node and its descendants are laid out on. |
`corrections` lists the operations in order, naming nodes by local name; `crop` names the node whose crop is the evidence.
`anchors_at_rev0` lists the anchors whose resolution `vectors/resolve.jsonl` records, and `receipts` the receipts, spot-checks and revocations to sign.
