- Add assertSupportedDetoxVersion (floor 20.0.0; v19 is unmaintained upstream)
  to the init, application, and convert-to-inferred generators.
- Preserve user-pinned versions: keepExistingVersions now defaults to true.
- Split migration 22.0.0 so the cross-major @config-plugins/detox bump is gated
  on `expo >=53 <54`, while the detox/jest-dom bumps stay ungated for bare
  React Native + Detox workspaces.
- Add the parameterized all-generators-enforce-floor spec.

NXC-4385

- Add the SDK 55 install lane (RN 0.83.6, React 19.2) and make it the default;
  add isExpoV55 detection. The v53 and v54 lanes are retained.
- Declare `expo` as a peer dependency; add assertSupportedExpoVersion
  (floor SDK 53) to every generator; keepExistingVersions defaults to true.
- Route SDK 55 jest setup through the v54 winter-runtime path.
- Gate SDK-specific migrations with `requires` and tighten 22.2.0 to a
  bilateral expo range.
- Add the floor spec; update the supported-versions docs.

NXC-4389

- Replace the single 0.79.3 literal with a per-minor version map
  (0.83/0.84/0.85, default 0.85) routed through versions(tree).
- Declare `react-native` as a peer dependency; add
  assertSupportedReactNativeVersion (floor 0.83.0) to every generator;
  keepExistingVersions defaults to true.
- Gate the remove-deprecated-deps migration on `react-native >=0.76 <0.79`.
- Add the floor spec; update the supported-versions docs.

NXC-4400

- @nx/remix stays Remix v2 (React Router v7 lives in @nx/react); document the
  split. Add assertSupportedRemixVersion (floor 2.0.0) to every generator.
- Stop generators from overwriting installed react/vite/@remix-run versions via
  keepExistingVersions, fixing conflicting pins with @nx/react.
- Add the parameterized all-generators-enforce-floor spec.

The react-native compliance change added `semver` (catalog:) to the plugin's
dependencies; record its resolved entry in the lockfile so frozen installs stay
in sync.

… docs

… them in the lockfile

Marks the `expo` and `react-native` peerDependencies optional (their inferred
plugins are gated on app-config presence) and records the resolved peers in the
lockfile so `pnpm install --frozen-lockfile` (CI) stays in sync.

The plugins detect support by major version (expo) / minor version (react-native),
so they work with any patch within each supported version, not just the .0.x line.
Caret reflects that; for the 0.x react-native versions caret and tilde are equivalent.

Moves each per-plugin assertSupported*Version wrapper into the plugin's
versions.ts (next to the minSupported*Version floor it already uses) and removes
the standalone assert-supported-*-version.ts files. No behavior change; the
all-generators-enforce-floor specs still exercise every generator's assert.

Defers RN 0.85 to a follow-up: 0.85 relocated its Jest preset to the new
@react-native/jest-preset package, which needs a separate generator change to
@nx/react-native's jest config. 0.83 and 0.84 still ship the old self-contained
jest, so they work with the current generator. Default install is now 0.84
(Active line); a 0.85 workspace falls through to latest constants.

Gated requires expo >=54.0.0 <55.0.0 to continue the existing SDK ladder. Versions mirror the expoV55* install constants.

…0.84

Gated requires react-native >=0.83.0 <0.84.0 (within the supported window). Versions mirror the 0.84 install constants.

…edExpoMajorVersion

Collapse the three duplicated isExpoV5x detection blocks into one getInstalledExpoMajor helper (graph-first detection unchanged), route via a per-major lookup table so the project graph is traversed once, and remove the unused getInstalledExpoMajorVersion. Also reword two stale "For Expo v54" jest comments. Behavior unchanged.

Remove the as-CompatMinors cast and widen versionMap to Partial<Record<number, ReactNativeVersions>> so indexing by minor() is type-safe without the cast. Behavior unchanged.

… detox peer optional

Pass keepExistingVersions to addDependenciesToPackageJson in the application and add-linting generators so re-runs no longer overwrite a user's pinned versions. Mark the detox peer as optional, matching the gated executor/inferred-plugin surfaces (consistent with the expo/react-native peers).

…unused version helpers

Pass keepExistingVersions to addDependenciesToPackageJson in the ensure-dependencies and add-linting helpers so the application/library generators stop overwriting a user's pinned Expo ecosystem versions. Remove the unused isExpoV54/isExpoV55 helpers (no src callers; the only question the code asks is isExpoV53) and their specs.

…or and simplify versions()

Pass keepExistingVersions to addDependenciesToPackageJson in add-linting so it no longer overwrites a user's pins. Drop the dead tree-less branch from versions()/getInstalledReactNativeVersion (every caller passes a tree) and inline the one-line helper.

The generator floor asserts detox >=20.0.0, but the peer advertised ^20.9.0, leaving a [20.0.0, 20.9.0) gap that passes the assert but fails the peer. Widen to ^20.0.0 so the two agree.

…rsion floor

The generator floor asserts @remix-run/dev >=2.0.0, but the peer advertised ^2.17.3. Widen to ^2.0.0 so the advertised peer agrees with the asserted floor.

@remix-run/dev is consumed only through opt-in surfaces — the build/serve executors (require.resolve at runtime) and the createNodesV2 inferred plugin gated on a remix.config file. The eager imports are type-only. Declare it optional via peerDependenciesMeta, matching the detox/expo/react-native primaries in this PR.

…indow

The peer was open-ended (>=0.83.0), advertising 0.85+ which the plugin explicitly defers (0.85 relocated its Jest preset to @react-native/jest-preset). Cap to >=0.83.0 <0.85.0 so the advertised window matches the install lanes. This also pulls the repo's own react-native dev resolution from 0.85.3 down to the supported 0.84.1. versions() still silently falls through to the latest lane above the window (no throw).
