Mark the package private and declare engines and exports (closes #6)

quak is not published, so package.json is marked private and loses its
files field. engines.node is >=22, the major version script/bootstrap
and the Dockerfile use. The exports map makes "." and "./package.json"
the only importable paths, so the CLI-only modules stay internal.

Model: opus-5-5

 # Completed Steps
 
+- 2026-09-23: Settled the package metadata (issue 6). quak is not published, so
+  `package.json` is marked `"private": true` and the `files` field is gone.
+  `engines.node` is `>=22`, the major version `script/bootstrap` and the
+  `Dockerfile` use. An `exports` map makes `.` and `./package.json` the only
+  importable paths; `runMetadataBackup`, the thumbnail helpers and their types
+  stay internal to the CLI.
+
+- 2026-09-23: Brought the README and this file in line with the tree (issue
+  111). The layout lists `src/library/` and the other source files, the backup
+  layout names `failures.json` and the optional `thumbnails/`, "Opening a
+  library" says what happens when the first refresh fails, the Testing section
+  gives the 60-second hard cap and 20-second target for `make test` and names
+  the 90-second `timeout` in the `Dockerfile` as the backstop for a hung test,
+  and "Tag v1.0.0" is no longer listed as the next step.
+
 - 2026-09-23: Tested `quak login` and `backup-metadata --exif` (issue 110).
   `loginCommand` takes its login function and its prompts from `CliContext`, and
   `bin/quak.ts` passes `Client.login` and the terminal prompts. Tests cover a
