release: 0.1.7 — new H glyph icon (desktop + Manager web) + manifest-driven Manager downloads

Visual brand refresh: replaced the desktop client + Manager web logos
with the new glossy gradient H glyph.

Desktop (cc-haha):
- src-tauri/icons/*: regenerated via `tauri icon` from new-icon.png
  (center-cropped 1024 square). Updates icon.ico/icns/png + 8 Windows
  Square*Logo sizes + iOS + Android mipmaps.
- public/app-icon.png + app-icon.svg: replaced. SVG is now a wrapper
  around the embedded PNG so existing <img src="…app-icon.svg"> refs
  keep working without recoloring tooling.
- Version bumped to 0.1.7 across tauri.conf.json, package.json,
  Cargo.toml.

Manager web (heicode/web/default):
- public/logo.png: 256x256 of the new glyph.
- public/favicon.ico: multi-size ico (16/32/48/64/128/256).
- public/heicode-logo.svg: same SVG-wraps-PNG trick as desktop.

Backend (heicode/controller/desktop_download.go):
- Already redeployed earlier today — the Manager web "Heicode 桌面客户端"
  page now sources its download URLs from the Azure Blob updater manifest
  instead of VM-local files. This is the fix for "still downloading
  Heicode_0.1.0_windows_x64_msi.msi"; the page will reflect 0.1.7 the
  moment the manifest publishes below.
