Rename: claude-image-proxy -> pixelpipe (Tier 1: code + docs)

Project rename for the Show HN launch with framing:
  'pixelpipe — what if Opus saw a UI instead of just append-only logs?'

Renamed everywhere:
  - kebab-case 'claude-image-proxy' -> 'pixelpipe' (42 occurrences)
  - snake_case 'claude_image_proxy' -> 'pixelpipe'  (5 occurrences)
  - 14 files touched: package.json, Cargo.toml, Cargo.lock, *.md,
    bin/cli.js, scripts/install.js, src/proxy.py, src/rust/src/main.rs,
    src/rust/examples/{render_sample,transform_only,diff_render}.rs,
    src/zig/build.zig

Effects on build artifacts:
  - npm package name -> 'pixelpipe'
  - Rust binary name -> target/release/pixelpipe (was claude-image-proxy)
  - Python cache dir -> ~/.cache/pixelpipe/ (was ~/.cache/claude-image-proxy/)

NOT YET DONE in this commit (Tier 2+3, handled in next commit):
  - Repo on-disk directory still ~/Downloads/repos/claude-image-proxy/
  - Cache dir on disk still ~/.cache/claude-image-proxy/ — Python proxy
    currently writes here. Will be migrated alongside the running services
    in a coordinated stop/move/restart sequence.

Validation: scripts/diff_transform.py still produces exactly 1 structural
diff (the PNG bytes, expected — different fonts Python/Menlo vs
Rust/JetBrains Mono). No regression from the rename.
