chore: delete unused lint wrappers + wire sync-checksums into release.yml

Audit of every script in the repo revealed three genuinely unused scripts
and one unwired helper. Fixed both.

Deleted:
- scripts/lint-all.sh, scripts/lint-android.sh, scripts/lint-ios.sh
  No workflow, pre-commit hook, README, or Makefile references them.
  .pre-commit-config.yaml calls `swiftlint` directly rather than these
  wrappers, so they were dead weight.

Wired up:
- release.yml now calls scripts/sync-checksums.sh against the flattened
  release-flat/ dir before creating the GitHub Release. Updates
  Package.swift SHA-256 lines to match the zips we're about to attach.
  Attaches the updated Package.swift as an audit asset; auto-commit back
  to main is a follow-up.

Kept after audit (all actively referenced):
- scripts/detect-mode.sh — sourced by every package-sdk.sh (5 refs)
- scripts/sync-versions.sh — release engineer pre-tag, release.yml validate
- scripts/sync-checksums.sh — now wired (see above)
- scripts/validate-artifact.sh — called by package-sdk.sh (Web/Kotlin/RN)
- sdk/runanywhere-commons/scripts/* — all referenced by CMake/workflows/
  devs; includes build-server.sh (wraps RAC_BUILD_SERVER CMake option)
- sdk/runanywhere-commons/tests/scripts/* — dev test runners, documented
- All per-SDK scripts/*.sh — referenced by README/workflows/other scripts

 | `sync-checksums.sh <zip_dir>` | Reads SHA-256 of freshly-built XCFramework zips and updates the `checksum: "..."` lines in root `Package.swift`. Run in the release workflow after native iOS/macOS builds produce the zips. |
 | `validate-artifact.sh <file>...` | Type-aware sanity check for each artifact extension (XCFramework Info.plist + slices, `.so` ELF magic, `.aar` classes.jar + jni, `.wasm` magic bytes, `.tgz` package.json). Same script runs locally and in CI. |
