Chromium Browser Extensions: report ID, version, host permissions and content script matches - #56

Problem

• Manifest V3 extensions list the sites they can access in host_permissions, not permissions. The rule didn't report them, so <all_urls> grants were only visible inside _Manifest.
• The extension ID and version were only available inside OSPath.
• Localized names were not resolved when the message key had capitals (e.g. __MSG_appName__). ResolveName lowercases the key, but the locale dict keys were not lowercased.

Changes

• New columns: ID, Version, ManifestVersion, HostPermissions and ContentScriptMatches (all content_scripts[].matches merged, without duplicates).
• Locale keys are lowercased before lookup, since Chrome message names are case-insensitive.
• Glob changed to Extensions/*/*/manifest.json so ID and Version always come from the right folders.
• Added Vivaldi to LinuxChromeProfiles.
• Added a golden test with an MV3 extension (with locale) and an MV2 extension.
