fix: restore docs/logo.svg so cached pi.dev preview reference resolves

[ranxianglei]

Fixes the broken image on https://pi.dev/packages/billion-context (图片加载失败).

Root cause (verified):

• npm is correct & live: published 0.1.105, pi.image -> docs/logo.png, and that PNG returns HTTP 200 (image/png, 1055148 B).
• pi.dev's stored record still points at docs/logo.svg (the value from v0.1.104), but fix: serve raster PNG for pi.dev preview image instead of SVG #701 deleted that file -> 404 -> broken image. pi.dev has not re-indexed to 0.1.105 yet and exposes no self-serve re-index button; its preview-media edge cache is only max-age=300.

Fix: restore docs/logo.svg so the currently-cached reference resolves immediately. No new publish needed — raw.githubusercontent.com serves master directly, so within ~5 min the broken image becomes the (older) SVG, and it flips to the hero PNG automatically once pi.dev re-indexes 0.1.105.

Content change, no version bump.

[bot] 🏷 Reviewed PR #703 against the code and live endpoints. Verdict: clean, correct, merge-ready.

Bug triage (root cause verified with evidence):

• npm 0.1.105 is live with pi.image → .../master/docs/logo.png, and that PNG returns HTTP 200.
• fix: serve raster PNG for pi.dev preview image instead of SVG #701 (eb88da9) is what deleted docs/logo.svg (34 lines) and flipped pi.image to logo.png.
• master/docs/logo.svg currently returns HTTP 404 — so pi.dev's still-cached reference to docs/logo.svg is exactly what breaks the image. Root cause holds.

Diff review:

• Single file, +34 lines, new-file only — no unrelated changes, no lockfile/whitespace churn, and no version bump (correct: content-only change). Passes the clean-diff gate.
• The restored docs/logo.svg is byte-identical to the exact file fix: serve raster PNG for pi.dev preview image instead of SVG #701 removed (verified via diff against eb88da9^:docs/logo.svg). We're restoring the known-good original, not a new design.
• The branch is a single commit sitting directly on the current master tip (merge-base == master tip) — no divergence, no conflict risk.

Why the fix works: pi.dev serves the preview straight from raw.githubusercontent.com/.../master/docs/logo.svg; once merged that path returns 200 again, so the currently-cached reference resolves within its max-age=300 edge window. When pi.dev later re-indexes 0.1.105, pi.image flips to the hero PNG automatically. No new publish needed.

Optional follow-up (non-blocking): after pi.dev has re-indexed 0.1.105, docs/logo.svg can be dropped again. Not required for this hotfix.

I can't merge (human-only per repo rules). Please merge when ready: #703
