Slice 1 of the Resource Manager (see docs/resource-manager.md +
plan in ~/.claude/plans/stateful-juggling-pike.md). Lays down the
read-only half: a JSON manifest schema with namespacing, a scanner
that walks /var/lib/furtka/apps/, and a `furtka` CLI with
`app list` and `reconcile --dry-run`. Reconciler / volume creation
/ docker compose calls land in the next slice.
- furtka.manifest: dataclass + load_manifest with required-field +
type validation. volume_name() injects the furtka_<app>_<vol>
namespace so apps can each declare a "data" volume without colliding.
- furtka.scanner: tolerant — broken manifest = ScanResult with error,
not an exception. Lets reconcile log + skip rather than abort.
- furtka.cli: text + --json output. argparse with `app list` and
`reconcile --dry-run`. main() returns int for clean exit codes.
- furtka.paths: FURTKA_APPS_DIR env override so tests don't need root.
- 19 new tests covering valid manifests, every validation branch,
scanner edge cases (missing root, broken manifest, sort order), and
the CLI subcommands.
