docs(privshield): rebrand project to "WiFi Veil"

Adopt "WiFi Veil" as the product name across all user-facing surfaces, keeping
VEIL (Verifiable Emission-shaping for Identity-Leakage prevention) as the
technical codename it's built on. Only prose, titles, descriptions, and the
console UI change — no code identifiers, file names, crate/npm `name` fields,
or the deterministic proof witness are touched, so `cargo test` and the C-core
host test are unaffected.

- Crate & research READMEs: title + defining line now "WiFi Veil (codename VEIL — …)".
- Cargo.toml / package.json / plugin.json descriptions: "WiFi Veil …".
- Console UI (veil-console.html): title, brand, and copy say "WiFi Veil".
- Firmware tree (README, per-provider READMEs, BUILD/INTEGRATION/MEASUREMENT):
  "WiFi Veil protector/core/shield".
- Harness manifest: recomputed SHA-256 digests for the four changed packaged
  files (README, package.json, CLAUDE.md, plugin.json) — all verified consistent.
