Implements AGENTS.md section 7 front-matter schema as a single-file, standard-library-only Python validator; no third-party YAML dependency and no framework. Adds the `make validate` gate, a 20-case fixture set and docs/content-schema.md. DoD satisfied: - make validate runs and exits 0 on an empty/clean content/ tree (missing dir and empty dir both exit 0; fixture ok-empty covers it). - Every violation class has a fixture under test/fixtures/fail-*; each exits non-zero with one line per violation (file:line: field: rule). `make test` runs all 20 cases: 20/20 pass. - Dangling artefact reference is fatal (fail-dangling-artefact; artefacts[].url must resolve to an existing in-repo L3 stub or asset). - Unknown front-matter field is fatal (fail-unknown-field), including unknown keys nested inside artefacts[]/metrics[]. - docs/content-schema.md committed; states the frozen schema, links to AGENTS.md section 7, and records that any later schema change is a breaking change requiring Sam's approval. - Scope respected: no content authored, no rendering, no site code. Files: Makefile, tools/validate_content.py, test/fixtures/**, docs/content-schema.md, .gitignore (__pycache__).
