Support --report flag for single export commands (colors, icons, images, typography)

Context

ExFig CLI branch feat/export-report (PR #66) adds --report flag for single export commands (colors, icons, images, typography). Currently exfig-action only supports --report for batch mode.

What needs to change

1. buildCommand() — extend --report to all export commands

Currently (line 491-496):

if (inputs.command === 'batch') {
  reportPath = inputs.report || path.join(os.tmpdir(), 'exfig-report.json');
  args.push('--report', reportPath);
}

Should also cover colors, icons, images, typography.

2. types.ts — add ExportReport interface

New report schema differs from BatchReport. Single-command report structure:

interface ExportReport {
  version: number;
  command: string;
  config: string;
  startTime: string;
  endTime: string;
  duration: number;
  success: boolean;
  error: string | null;
  stats: { colors: number; icons: number; images: number; typography: number };
  warnings: string[];
  manifest: AssetManifest | null;
}

interface AssetManifest {
  outputDirectory: string;
  files: AssetManifestFile[];
  deleted: string[];
}

interface AssetManifestFile {
  path: string;
  assetType: string;
}

3. parseReportFile() — handle both report formats

Detect report type (batch vs single) and parse accordingly. Batch has results[] array, single has command field.

4. action.yml — update report input description

Remove "(batch mode)" from: 'Path to write JSON report file (batch mode)'

5. Report output for single commands

Set report_json output for single export commands too (currently only set in batch mode).

Notes

• Backward-compatible: without these changes, action falls back to regex parsing for single commands — nothing breaks
• Blocked on ExFig CLI release that includes feat/export-report
