alexmandClaude a4eecb4d5b refactor: move the reference implementation to src/paperspec
The oracle had two import names, `tools.oracle` for the tools and
`paperspec` for other repositories, which could load the same code twice
in one process and needed a gate keyed on the module name. It now lives
in the standard src layout under its one name.

- git mv tools/oracle -> src/paperspec; the 22 rule modules are unchanged.
- The tools import `paperspec`. `tools/__init__.py` now holds the Python
  3.14 and cryptography/jsonschema check and puts src/ first on sys.path,
  so the tools run this checkout's code with or without pixi. The
  package's own __init__ checks nothing and exposes __version__.
- pyproject.toml: version from git tags via setuptools-scm
  (guess-next-dev, node-and-timestamp, src/paperspec/_version.py,
  gitignored). The packages stay listed rather than found because
  schemas/, sql/ and vectors/ stay at the root: the spec links to them and
  the site serves the schemas at their $id URLs.
- pixi.toml: a `dev` feature and environment with setuptools,
  setuptools-scm and python-build, and `pixi run -e dev wheel`.
- check.py scans src/paperspec for rule IDs; README, CONTRIBUTING, the
  FAQ, the overview, the vectors and tools READMEs and the changelog point
  at the new path. The FAQ no longer says the oracle is not a library.

pixi.lock is not re-solved in this commit: with a dynamic version, pixi
builds the package metadata to lock, which needs the conda environment
installed. Run `pixi lock` and commit the result before pushing; the site
workflow installs with --locked.

pixi run check passes; no computed value, vector, fixture, schema or SQL
file changed.

"""Validate packages, or run the correction gate on proposals against a package.
Non-normative tooling.
Usage: python3 tools/validate.py PACKAGE [PACKAGE ...]
python3 tools/validate.py --correction PROPOSALS PACKAGE
A package is a folder, or a zipped package (`.sct.zip`), which is unpacked under the rules of spec/12 §12.2
before it is checked. Each is checked as spec/22 §22.2 describes, and each failure printed as
`package: where: rule: message`.
With --correction, PROPOSALS is a JSON file holding one proposed correction, or a JSON Lines file of several
applied in order. Each runs through the gate (spec/11 §11.4) against the package's current state, and the record
it would append to corrections.jsonl is printed, until one is refused. Nothing is written.
Exit status: 0 when everything is valid, 1 when something is refused, 2 for a usage error.
