Only set supported scale if scale > 1, also convert it to optional<int> so the config format would be work for GKeyFile (#109)

Summary by CodeRabbit

• Bug Fixes
  • Theme generation now records supported scale settings consistently. When the calculated maximum scale is 1, no scale setting is written; when it is greater than 1, the calculated value is saved in the expected format. This helps ensure generated themes reflect their supported scale without adding an unnecessary setting for a maximum scale of 1.

📝 Walkthrough

Walkthrough

The theme generator now omits SupportedScale when the calculated maximum scale is 1 or less. When it exceeds 1, the generator writes the value under SupportedScale.Value.

Changes

Theme scale output

Layer / File(s)	Summary
Write the supported scale setting src/plasmathemegenerator/main.cpp	generateTheme omits SupportedScale when maximumScale is 1 or less. For higher values, it writes SupportedScale.Value.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~5 minutes

Change: Bug fix

Merge Risk: 🟡 Moderate · up to 9b41c

Generated themes will not use their high-resolution assets with Fcitx 5.1.23. Correct the setting format before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 9b41c

Some supported Fcitx versions may not read the new scale setting, causing generated high-resolution themes to lose scaled-asset support. The change does not appear to introduce a new security boundary or privilege.

Retained concerns

• Low · architecture · inferred: For a consumer with Fcitx 5.1.23’s scalar SupportedScale option, generated values above 1 are written to a child the option does not read, leaving scaled assets unselected.

Security review details

Security Blast Radius

• inferred — The identified effect is confined to generated theme configuration and its external readers; no new security-sensitive reachability or authority is evident from the changed output path.

Trust Boundaries and Controls

• observed — The application already accepts an output path and writes theme files. This PR changes neither that input nor the write destination selection.
