v2.11.0

Highlights

• Unified stored-tag reading between CLI and GUI (#265, #267): the AAC / ID3v2 / APE dispatch for reading stored gain tags is now a single library API, read_gain_tags_auto, returning an owned StoredGainTags snapshot with a GainTagSource enum. Both mp3rgain -s c and the GUI's Check Stored Tags render from it, eliminating a recurring parity-drift risk between the two frontends. CLI output is byte-identical to v2.10.0.
• Internal code consolidation: duplicated helpers across the CLI command/processor layers and the GUI (album analysis, track analysis, error reporting, RG value parsing) were extracted into shared functions, shrinking the codebase without behavior changes.

This is a refactoring and maintenance release — no user-facing behavior changes.
