alexmandClaude 607062056f feat!: pin Python 3.14 and Unicode 16.0, and make the tools commands
Python and Unicode
- requires-python is >=3.14,<3.15: 3.14 is the only Python with the
  Unicode 16.0 data the specification pins (3.13 has 15.1, 3.15 has 17.0).
- `import paperspec` raises ImportError unless unicodedata reports
  paperspec.UNICODE_VERSION (16.0.0), so a source checkout or an install
  that bypasses requires-python cannot compute values on other data.

Commands
- tools/{check,build,validate,load,stress,site}.py move with history to
  src/paperspec/cli/ and install as paperspec-check, -build, -validate,
  -load, -stress and -site; each also runs as `python -m paperspec.cli.X`.
- paperspec.cli.require() exits with "install paperspec[tools]" when
  cryptography or jsonschema is missing; paperspec.cli.checkout() finds
  the repository the check, build, stress and site commands work on (the
  editable install's own checkout, else the one around the current
  folder) and exits with a message outside one. tools/__init__.py is gone.
- validate and load read the schemas and SQL through the new
  paperspec.resources.path(), which finds them in a wheel and in an
  editable install alike, so they work anywhere the package is installed.
- check runs the rebuild as `python -m paperspec.cli.build`.
- build still writes the provenance tool label "paperspec tools/build.py":
  it is part of every hashed and signed fixture.
- pixi tasks and the check workflow run the commands; tools/README.md
  documents them, and the other docs name the commands instead of paths.

License
- LICENSE.md gives `src/` Apache-2.0 alongside `tools/`. Since the
  previous commit moved the code to src/, no row had covered it.

pixi run check passes (run as `python -m paperspec.cli.check` with src/ on
the path, since this environment cannot install the entry points); the
byte-for-byte rebuild matches, so no fixture or vector changed.
pixi.lock still needs `pixi lock`.

The paperspec specification

This specification states exactly what each paperspec file holds and how every value in it is computed. The schemas, SQL, JSON-LD context, registries, vectors and fixtures are normative too, and each chapter says which of them it relies on. A chapter and a vector that disagree signal a bug, so please report it in the repository, https://git.scient.ing/infra/paperspec.

Two readers will get the most from it: implementers who build a reader, writer, converter or checker, and experts who want the precise rules. Newcomers should start with the guides, which explain what the formats are for. This text assumes you know why and tells you how.

Reading paths

Find the row for the job you are doing and read its chapters after those in the first row. Chapter numbers are those in the table below.

If you are writing Read
Anything at all 0, 1, 3, 4 and 5: introduction, conventions, nodes, identity and the content values.
A reader of packages Then 2, 6, 7 and 12: the model, anchors, geometry and the package.
A converter Then 9, 10 and 11: figures and tables, references, and corrections with the gate.
A store or a server Then 8, 13, 14 and 23: receipts, the database form, rights, and the transparency log.
A writer or reader of annotation, teaching or data files Then 15 to 21.
A validator Chapter 22, with registry/rules.json.
