fix(pstack): shrink logo under 512KiB

[poteto]

Summary

Marketplace rejected / complained that the pstack logo was too large (~1.9MB). Resized with LANCZOS + oxipng (no palette quantization) to the largest square that stays under 512KiB.

• pstack/assets/logo.png: 1254×1254 (~1.9MB) → 626×626 (~512KiB)
• version 0.14.7 → 0.14.8

Verification

• File size ≤ 524288 bytes
• PNG RGBA, sharp downsample (no JPEG/webp)

---

Note

Low Risk
Packaging-only change (image resize and version bump); no runtime or security impact.

Overview
Resizes the pstack marketplace logo so it meets the 512KiB asset limit (from ~1.9MB at 1254×1254 down to ~512KiB at 626×626, LANCZOS + oxipng, still RGBA PNG).

Bumps the plugin release to 0.14.8 in plugin.json so the smaller assets/logo.png ships with a new version.
