Nova DSO Tracker v5.9.0 released

Scan Frame — Discover DSOs within your current framing rectangle via SIMBAD ADQL search, with magnitude filtering and cached results
Scan Frame Min Size Filter — Filter discovered objects by minimum apparent size to hide anything smaller than your eyepiece’s resolution limit
Scan Frame FOV Limit — Scan Frame is automatically disabled when the framing rectangle exceeds a maximum FOV, preventing useless wide-area queries
Scan Frame Object Popup — Click any discovered DSO to view its name, SIMBAD object type label, RA/Dec in sexagesimal format, Wikipedia summary with link, and an “Add to Database” button
Proactive Outlook Cache Pre-warm — Weather outlook cache is now pre-warmed on dashboard load to avoid first-look delays

Robust Version Parsing — Pre-release version strings like “5.9b” no longer crash the update checker; non-numeric suffixes are safely stripped
Upload Size Limits — File uploads are now capped (50MB app-wide, 10MB for ASIAir/PHD2/NINA logs, 5MB for session images) to prevent server strain
Stuck Button State Fix — Scan Frame button now correctly resets its visual state each time the framing modal reopens
Outlook Cache Handling — Fixed a crash when the outlook cache pre-warm runs before a location is selected on g

Fixed scan_frame ADQL query to work with SIMBAD schema change (removed deprecated vmag column)
Bad SIMBAD rows with unparseable RA/Dec are now skipped gracefully instead of causing a 500 error
Fixed Scan Frame button getting stuck in disabled state when framing modal reopens

Added Scan Frame documentation (how it works, min size filtering, object popup interaction, FOV limit) to the Framing Assistant help in 6 languages: English, German, Spanish, French, Japanese, and Chinese

Extracted applyMinSizeFilter as a reusable function shared between catalog and scan-frame filtering
Added /api/scan_frame endpoint with in-memory cache (1-hour per-user TTL) and pytest tests
