Add storage tests for URL parsing and every in-process backend (closes #66)
internal/storage had no tests. This adds table-driven ParseStorageURL
coverage and a shared Storer conformance suite, defined once in
conformance_test.go and run against every backend that can run
in-process: file:// over a temp dir and s3:// over the same in-memory
S3 harness (gofakes3 + s3mem) that internal/s3 and the not-found test
use, so a new backend inherits the contract by passing its constructor.
The rclone backend gets construction and argument-shaping tests via
rclone's in-process ":local" backend, plus the missing-remote error
path; a comment records that its data-plane operations need a configured
remote and so cannot run in a unit test.

Tests only; no production code changed and no defect surfaced.

// The rclone backend is a thin adapter over the rclone library: it turns a
// (remote, path) pair into rclone's "remote:path" string, hands it to
// rclone, and maps rclone's own results back to the Storer interface. What
// can be tested in-process, without a configured remote or network, is that
// adapter layer — how the arguments are shaped and how construction errors
// are reported. The data-plane operations (Put/Get/List/Delete) are rclone's
// own, exercised against a real provider (drive, s3-via-rclone, ...), which
// needs a configured remote with credentials and network access and so is
// out of reach of a unit test. The shared Storer conformance suite therefore
// runs against the in-process file and s3 backends; the rclone backend
// inherits that contract once a remote is configured.
//
// These tests use rclone's ":local:" on-the-fly backend, which addresses the
// local filesystem directly without any configured remote, so construction
// runs entirely in-process.
// TestNewRcloneStorerConstruction checks that a valid remote constructs a
// backend and that Info() reports the shaped "remote:path" location.
