refactor(cli): demote check from visible_alias to deprecation shim

`omnigraph check` was a clap `visible_alias` on `lint`, advertised in
`--help` as an equivalent canonical name. Per MR-981 §6 (long-form
flags as canonical, short forms as visible aliases), visible aliases
on subcommand names hurt agent CX: agents emit either spelling
depending on training-data drift, and there's no length signal
pointing at the canonical name.

Changes:

* Remove `#[command(visible_alias = "check")]` from the `Lint` variant.
  `omnigraph --help` now shows only `lint`.
* Add bare `check` to `rewrite_deprecated_argv` so `omnigraph check
  <args>` still works — it rewrites to `omnigraph lint <args>` and
  emits a one-line stderr deprecation warning, matching the existing
  pattern for `read` / `change` / `query lint` / `query check`.
* Fix the nested `query check` shim to substitute `check` -> `lint` in
  the rewritten argv (previously it relied on `check` being a
  visible_alias to reach the `Lint` variant).
* New test `deprecated_check_top_level_rewrites_to_lint` covers: bare
  `check` produces identical stdout to `lint`, emits the deprecation
  warning, and `check` does NOT appear as an alias in `omnigraph
  --help`.
* Release notes updated to reflect the deprecation-shim treatment and
  cross-reference MR-981 §6 reasoning.

Cargo / Go users typing `check` still work indefinitely; one stderr
nudge per invocation teaches the canonical name. Agents see only
`lint` in `--help --json` so they emit one canonical form.

67/0 omnigraph-cli tests pass; 39 workspace test suites green.

### Query / mutation rename
- **`ChangeRequest` field rename**: `query_source``query`, `query_name``name`. Both legacy names continue to deserialize via `#[serde(alias = "...")]`, so existing clients sending the old JSON keys keep working. CLI remote calls against `/change` still emit the legacy keys verbatim through the `legacy_change_request_body` helper so a newer CLI talking to an older server keeps working byte-for-byte.
- **CLI `omnigraph query lint` / `omnigraph query check`** are now top-level `omnigraph lint` / `omnigraph check`. The legacy invocations remain as argv-level shims that rewrite to the canonical form and print a one-line deprecation warning to stderr.
- **CLI `omnigraph query lint` / `omnigraph query check`** are now top-level — canonical name is **`omnigraph lint`**. The three deprecated invocations (`omnigraph query lint`, `omnigraph query check`, and bare `omnigraph check`) remain as argv-level shims that rewrite to `omnigraph lint` and print a one-line stderr deprecation warning. `check` is deliberately **not** a clap `visible_alias` on `lint` — two equivalent canonical names would split agent emissions between them depending on training-data drift, so the deprecation pattern (rewrite + warn) gives one unambiguous canonical name in `omnigraph --help`.
