Beta 1.2

Beta 1.2 (v1.2.0, commit 034f101). Self-contained single exe for Windows 10 1809+ / 11. SmartScreen warning expected until signing/reputation (see SCOPE A2).

Fixes:

• Save button dims when clean + green Saved receipt (#1)
• Running version shown bottom-left of Settings + logged at startup (#2)
• Custom color Pick buttons with alpha preserved + live preview (#3)
• Tray Open logs folder + Clear log (#4)
• Tray Test confirm is now a dry run, never touches Games list (#5)
• Add focused app uses last non-self focus, never grabs TimeNotice.exe (#6)
• Detect tab live readout with top-GPU verdicts (#9)

Reports still need: what doing / expected-vs-saw / settings.json + debug.log (see #7).
