DirettaRendererUPnP v2.5.3

Fixed

• Web UI: comma-separated values are canonicalised at save time (reported by Dominique while wiring IRQ_INTERFACE through the fedora-audiophile-setup stable-naming refactor on 2026-06-02). A user typing eth-diretta, eth-lan in the web UI used to persist that literal string — natural for free-text input but cosmetically inconsistent with the documented enp1s0,enp2s0 form. The shell wrappers (start-renderer.sh and the same logic mirrored in install.sh) already trim defensively per-element (tr -d ' '), so this was not a functional bug; IRQ pinning worked regardless. The fix eliminates the cosmetic divergence on disk and protects any future consumer of /etc/default/diretta-renderer that reads the file without trimming. Applied to the five known comma-list fields: IRQ_INTERFACE, IRQ_CPUS, CPU_AUDIO, CPU_DECODE, CPU_OTHER (full profile); CPU_AUDIO, CPU_DECODE, CPU_OTHER (minimal profile — IRQ tuning belongs to the downstream distro on that flavour). Idempotent: values that are already canonical pass through unchanged, so configs only get rewritten when the user explicitly opens and saves the form. Symmetric fix shipped in slim2Diretta v1.4.2.

Changed

• Profile-driven normalization machinery in the web UI save handler — setting JSON declarations gain an optional "normalize" field. Currently the only supported rule is comma_list (re.sub(r'\s*,\s*', ',', value.strip())), but the structure is in place for any future per-field input canonicalisation (e.g. lowercase MAC, trim whitespace, normalize boolean strings). Adding a future comma-list field to either profile is one line of JSON; no Python change needed.
