docs: surface LegionProxy sponsorship

Add the sponsor entry to both README variants so GitHub visitors see the same partnership information in Chinese and English. The logo is kept in the docs image tree so the table can render without relying on a remote asset.

Constraint: Sponsorship section should use the table layout shown by the user
Rejected: Text-only sponsor row | it missed the logo-focused layout requested by the example
Confidence: high
Scope-risk: narrow
Directive: Keep README.md and README.en.md sponsorship entries aligned when adding or editing sponsors
Tested: git diff --cached --check
Not-tested: GitHub web rendering after push
