Remove executable Dolt validator package

[TonisOrmisson]

What changed

• removes the installable openstatspec-specification Python package
• removes the executable Dolt declaration validator, its tests, and its tool wrapper
• removes package installation and validator-test steps from specification CI
• removes the package-specific PyPI publishing workflow
• removes the unreleased 0.2.1 package path from the changelog and roadmap
• removes the validator-coupled Dolt declaration manifest and empty evidence-registry guidance
• records that Transformation Plan/frontend profile 0.2 is already merged

What remains

• the authoritative Dolt dialect profile in sql/dialect-profile-baseline.json
• existing cross-adapter capability declaration requirements in the normative SQL profile documents
• existing specification repository validation
• all pending adapter, service-matrix, exact-commit, and tag-protection gates for v0.3.0

Architecture boundary

The specification repository publishes normative documentation, schemas, and declarative fixtures. Executable adapter/declaration validation belongs in implementation or adapter repositories.

Validation

• python3 tools/validate_repository.py
• git diff --check
• exact-head CI: https://github.com/OpenStatSpec/specification/actions/runs/30906027254
• independent strong review: clean

Release impact

No corrective release is required. openstatspec-specification==0.2.1 was never published, and no v0.2.1 tag or GitHub Release exists. Keep this work under Unreleased; the next possible specification release remains v0.3.0 after the documented gates pass.

Resolved the Codex P2 on exact head 99dd1cee378be918cbcd066b9fd934eb5a92aa8c without restoring executable validation. The remaining declaration manifest and empty declaration/evidence registry guidance were removed entirely because their cross-artifact evidence invariants cannot be expressed by that metadata file alone. The authoritative Dolt dialect profile and existing normative capability-declaration requirements remain unchanged; concrete declarations and evidence belong in implementation/adapter repositories with their own validation. Exact-head push and PR CI are green.

Please review exact head 99dd1cee378be918cbcd066b9fd934eb5a92aa8c. The executable/package validator stack and its declaration/evidence registry artifacts are removed; the authoritative Dolt dialect profile remains unchanged. Please assess the specification/implementation boundary and release metadata.
