andrew 617a77d7c8 schema-lint chassis v1 (WIP): tier surfacing + plan doc
First commit of the chassis v1 branch. Lands a small, foundational
slice without behavior change, plus a planning doc that lays out the
remaining 7 commits in sequence so the PR can be reviewed
incrementally.

This commit:

- Adds SchemaMigrationStep::diagnostic() returning the full
  &'static DiagnosticCode (family + tier + severity) for
  UnsupportedChange steps with codes. Renderers can now reach the
  tier without re-implementing the code → tier lookup.

- CLI `omnigraph schema plan` output now displays tier alongside
  code:

    unsupported change on node:Person.age [OG-DS-104, destructive]:
        removing property 'Person.age' is not supported in schema
        migration v1

  Operators see at-a-glance the kind of risk each rejection
  represents — not just the rule identifier.

- No behavior change. All 11 existing schema_apply tests still pass.

Planning doc at docs/schema-lint-v1-plan.md tracks the 7 remaining
commits to bring v1 to feature-complete:

  1. (this commit) Tier surfacing in plan output.
  2. Soft / Hard mode enum on drop steps.
  3. Tombstone fields on catalog IR.
  4. Planner emits DropProperty { Soft } by default.
  5. Apply path implements Soft mode.
  6. Convert PR #62 destructive-rejection tests.
  7. --allow-data-loss flag + Hard mode.
  8. (optional) Tombstone unhide / restore command.

Delete the planning doc when v1 lands. Intentionally checked in to
the WIP branch so the scope is reviewable; not intended as a
permanent doc.
