v0.0.7

Reworked settings page. Cards are reordered into a natural flow with the master dry-run switch on top and the dangerous replace policy at the bottom above Save. Controls that don't apply right now (specific encoder, VMAF threshold, backup retention, the hard-replace warning) are hidden until they're relevant. Quality guidance now adapts to the chosen codec instead of a one-size HEVC hint. The settings that had no UI are now exposed: include/exclude path globs and a library multi-select, plus a Skipped counter and clickable detected-encoder chips. Library scoping is now actually enforced (and fails closed). Also fixes a stuck loading spinner on save errors and an empty-number-field footgun. 77 tests.
