Add 0.0.1 ProvenanceRecord spec (common, model-agnostic parts)

[ANierbeck]

What this does

Fills in the 0.0.1 skeleton on main with the concrete ProvenanceRecord shape developed and stress-tested across four open-model corpora. Only the common, model-agnostic solution parts land here; the model-specific example records and stress-test notes stay on dedicated branches for dev-list discussion.

What lands (10 files)

• schema/0.0.1/sourcelume.schema.json — ProvenanceRecord JSON Schema. Required: id, type, identifier, name, license, creator[], created, added, contentCreated, origin, custodyChain[]. Optional: version, licenseScope, licenseNote, licenseCategory, licenseHistory.
• schema/0.0.1/sourcelume.shacl.ttl — matching SHACL shapes.
• context/0.0.1/sourcelume.jsonld — JSON-LD context. Reuses dct:/schema: where equivalents exist; keeps the sl: namespace minimal. Uses main's sl: prefix and version-inclusive namespace IRI.
• spec/0.0.1/index.md — normative prose (field table + License IRI conventions subsection).
• tools/validate.py — Python validator (JSON Schema + SHACL). Exits 0 with "nothing to validate" when examples/ is empty.
• mappings/ — draft crosswalks to Croissant, the SPDX AI Profile, and OTDI.
• pyproject.toml, uv.lock — Python tooling.

What stays on branches (not in this PR)

• All 30 examples/*.jsonld model-specific records + 3 examples/prototypes/
• All notes/stress-test-*.md and notes/mimir-dynaword-sources.md

These remain on common-corpus-stress-test (and future dedicated branches) for dev-list discussion of the still-open gaps (B, C, D, E).

The four additive license fields

All optional, non-breaking; records that omit them validate.

Field	Purpose
licenseScope	Qualifies jurisdiction-scoped licenses (esp. public-domain claims whose PD status is not worldwide).
licenseNote	Flags when a license IRI is materially misleading (e.g. reflects a processing artifact rather than intended selection).
licenseCategory	Classifies the licensing model (open-source, open-data, public-domain, agreement-supplied, use-restricted, risk-based, other) so it is checkable at a glance rather than only by reading the IRI.
licenseHistory	Records prior licenses when a dataset's own license changed over time; current license stays in license.

Conventions followed

• Namespace: main's sl: prefix + version-inclusive IRI (https://sourcelume.apache.org/ns/0.0.1#), preserved.
• Vocabulary reuse: dct:/schema: terms where equivalents exist; sl: kept minimal.
• Generic descriptions: no model-specific names appear in the common files (descriptive text uses generic examples).
• No examples/ or notes/ dependency: validator is tolerant of an empty examples/ dir; spec has no dangling links to example files.

Validation

• tools/validate.py exits 0 on main + this PR (no examples present).
• On the stress-test branch (with examples), 30/30 records PASS against this schema + SHACL.
