rename: Jarvis -> Jervis target, scheme, and folder throughout

The bundle-ID and display-name renames weren't enough — the actual
Xcode target/product name was still "Jarvis", which drives CFBundleName,
Xcode's Organizer archive list, the .xcodeproj filename, and the scheme
name. Renamed all the way through:

- project.yml: top-level name, target key, PRODUCT_NAME, source/info paths
- Jarvis/ -> Jervis/ (source folder, git-tracked as renames, no content
  diffs on the moved files)
- .gitignore, CI workflows, README, CONTRIBUTING: Jarvis.xcodeproj /
  scheme Jarvis -> Jervis.xcodeproj / scheme Jervis

Verified: xcodebuild -scheme Jervis succeeds, produces Jervis.app,
CFBundleName/CFBundleExecutable/CFBundleDisplayName all read "Jervis".
CFBundleIdentifier intentionally stays com.kisani.jarvis (per prior
decision — bundle ID isn't user-facing anywhere including Organizer).

Swift type names (JarvisApp, JarvisWordmark, etc.) and the Gitea repo
name/URL are unchanged — pure internal source identifiers, not user or
developer-facing product identity.
