andrew 7ecbda6b4e schema-lint v1 commit 2: DropMode + dormant Drop* variants
Second commit of the chassis v1 branch. Lands the type-level shape
of soft/hard drops without wiring them up. Variants are reachable
from emitters but the planner doesn't produce them yet; the apply
path returns an explicit not-yet-implemented error if one shows up
via deserialization.

Added:

- `DropMode { Soft, Hard }` — orthogonal to `SafetyTier`. Tier
  classifies the rule's risk class; mode is the operator's intent
  for data treatment.
    - `Soft` → catalog tombstone, data retained. Tier: safe.
    - `Hard` → Lance-level removal. Tier: destructive; will require
      --allow-data-loss to apply (commit 7).

- `SchemaMigrationStep::DropType { type_kind, name, mode }` and
  `SchemaMigrationStep::DropProperty { type_kind, type_name,
  property_name, mode }` variants.

- Re-export `DropMode` from `omnigraph_compiler::DropMode` so
  downstream crates don't reach into the catalog submodule.

- CLI `render_schema_plan_step` arms for both variants, surfacing
  the mode in plan output: `drop property 'Person.age' of node
  'Person' (soft mode)`.

- `apply_schema_with_lock` exhaustive match arm for the two new
  variants that returns `manifest_internal` with a clear
  not-yet-implemented message. If a SchemaIR JSON containing
  Drop{Type,Property} arrives (e.g. from a future tool or hand-
  written), the apply path fails explicitly rather than silently
  misclassifying.

- Two new in-source tests:
    - `drop_steps_round_trip_through_serde` — pins the wire shape
      for all four (variant × mode) combinations.
    - `drop_mode_serde_uses_snake_case` — pins external-tool-
      friendly serialization (`"soft"` / `"hard"`).

Build: clean, only pre-existing warnings.
Tests:
- omnigraph-compiler schema_plan: 6/6 (4 existing + 2 new).
- omnigraph-engine schema_apply: 11/11 (unchanged — planner still
  emits UnsupportedChange for removal paths).

Next commit (commit 3 per docs/schema-lint-v1-plan.md): add the
`tombstoned: bool` fields to NodeIR / EdgeIR / PropertyIR for the
catalog representation of soft-mode tombstones.
