T-1: GitRemote value type + parser in SharedModels

[kirich1409]

Description

Add MacApp/Packages/SharedModels/Sources/SharedModels/GitRemote.swift:

public struct GitRemote: Sendable, Equatable, Codable {
    public let host: String
    public let owner: String
    public let repo: String
    public let `protocol`: GitRemote.Protocol
}

public extension GitRemote {
    enum Protocol: Sendable, Equatable, Codable { case ssh, https, scp }
    static func parse(_ url: String) -> GitRemote?
}

public struct GitRemoteEntry: Sendable, Equatable {
    public let name: String
    public let url: String
}

parse supports:

• https://github.com/owner/repo.git
• https://github.com/owner/repo
• git@github.com:owner/repo.git
• ssh://git@github.com/owner/repo.git
• https://<token>@github.com/owner/repo.git
• Repo names with dots (my.repo)
• GHE hostnames parsed as-is (classification is done by GitHubFeature, not here)

GitRemoteEntry — raw name+url pair from git remote -v parsing (before URL classification).

Acceptance criteria

• GitRemote.parse("https://github.com/owner/repo.git") → host/owner/repo match, protocol == .https
• GitRemote.parse("git@github.com:owner/repo.git") → host/owner/repo match
• GitRemote.parse("https://github.com/owner/my.repo") → repo == "my.repo"
• GitRemote.parse("https://example.com"), "", "not a url" → nil
• GitRemote.parse("https://ghe.acme.corp/owner/repo.git") → parses, host == "ghe.acme.corp"
• All types Sendable, pure Swift 6 (no @preconcurrency)
• swiftlint lint --strict green
• Unit tests in SharedModelsTests cover all formats + invalid inputs
• xcodebuild build + xcodebuild test green for Relay scheme
