Release 0.7.0-beta1

Added

• npm-style lock files. Update-PSDependLock resolves supported Dependencies
  and their transitive dependencies to exact versions in <name>.lock.json.
  Invoke-PSDepend and Get-Dependency honor locks automatically, install
  transitive packages first, preserve separate root installation contexts,
  reject malformed or unsafe lock data, and detect changes to Dependencies,
  versions, resolution sources, and DependencyScript parameters. -IgnoreLock
  opts out. Resolution is greedy and does not backtrack to older parent versions.
• New Resolve PSDependAction for PSGalleryModule, PSResourceGet,
  PSGalleryNuget, Nuget, Chocolatey and Npm: query the source and return
  an exact version without installing. Npm accepts npm semver ranges and pins
  only the declared package; its subtree remains under npm's package-lock.json.

Fixed

• Invoke-DependencyScript -PSDependTypePath is now passed through to the
  type/script lookup instead of always reading the module's PSDependMap.psd1.
• Lock resolution now exhausts paged NuGet v2 feeds, honors exact prerelease
  requests, rejects ambiguous framework-specific dependency constraints, and
  re-resolves whenever a combined constraint changes so the highest matching
  version remains locked.
