Adds the reverse conversion (sab -> sax) and makes the tools usable without remembering paths on the command line. - sax.py: decoder ported from OfflineApp.decodeAppBinary + encodeAppXml. Rebuilds the tree from the firstChild/nextSibling chain and writes XML the way XWriter does. Reproduces java.lang.Float.toString, and rounds manifest defaults to f4 before comparing them - otherwise props equal to their default (0.1) get written where sedonac omits them. - sab2sax.py: CLI dispatching on the input extension, like sedonac. sab.py still runs and hands off to it. - config.py: sedona.home lives in system.properties. If it is missing or has no manifests/, a folder chooser opens and the answer is written back. File choosers for the input, save dialogs for the output; the default output name carries a timestamp so a run never overwrites the previous one. - verify.py: checks both directions plus a sab -> sax -> sab round trip, and points at testprogram/ where the test files actually live. All three checks pass byte-identical against the checked-in sedonac output. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
