Harden the JPEG EXIF scan against malformed input (closes #11 )

The segment scan behind `backup-metadata --exif` now checks every segment length against the bytes that remain and stops on lengths under 2, so a truncated or corrupt original can neither throw nor loop. A malformed or unparseable EXIF segment is recorded as `imageMetadata.exifError`, and a failure to read the original as `imageMetadataError` in the per-file JSON, instead of the field being silently left out. Tests use short hand-built byte arrays. Model: opus-5-5

- 2026-09-22: Stopped `make test` collecting tests from checkouts nested under
-  `.claude/` (issue 25). vitest ignores `.gitignore` when finding tests, so a
-  nested checkout ran the whole suite again; `vitest.config.ts` now adds
-  `.claude/**` to vitest's default excludes, and
-  `test/packaging/nested-checkout.test.ts` plants a nested checkout in a temp
-  directory and fails if vitest would collect it.
- 2026-09-22: Dropped the deprecated `@types/libsodium-wrappers-sumo` stub from
-  `devDependencies` (issue 27). It shipped no declarations; the types come from
-  `libsodium-wrappers-sumo` itself. `yarn.lock` regenerated by `yarn remove`.
 - 2026-09-22: Hardened the client session lifecycle (issue 10).
  `Client.fromJSON` checks every snapshot field and each key's decoded length
  and names the bad field; `toJSON` reads the token through
