Honor configured protocol for automatic repository clones

[MisterJimson]

Summary

• keep the default Create & Clone flow protocol-aware instead of hardcoding a concrete clone URL
• honor GitHub CLI's per-host git_protocol setting for automatic clones
• preserve explicit HTTPS and SSH behavior, using HTTPS as the safe fallback when a provider cannot report a preference
• add focused web, GitHub CLI, and repository-service regression coverage

Why

The Create & Clone UI passed repository.sshUrl directly to the clone operation, bypassing the existing auto protocol path. Remote servers authenticated with gh over HTTPS but without a GitHub SSH key therefore failed to clone private repositories even though HTTPS access was valid.

The UI now submits the provider and repository identity with protocol: "auto". For GitHub, repository lookup reads gh config get git_protocol --host <host> and carries that preference into clone selection. A reported SSH preference still uses SSH, a reported HTTPS preference uses HTTPS, and an unavailable preference falls back to HTTPS instead of recreating the original authentication failure.

Explicit URL clones remain unchanged.

Fixes #4203.

Testing

• vp test run apps/server/src/sourceControl/GitHubCli.test.ts apps/server/src/sourceControl/SourceControlRepositoryService.test.ts apps/web/src/components/CommandPalette.logic.test.ts (22 tests passed)
• pnpm --filter @t3tools/contracts typecheck
• pnpm --filter t3 typecheck
• pnpm --filter @t3tools/web typecheck

An isolated UI smoke-test startup was attempted, but this nightly checkout's Vite+ dev server is independently blocked by Tsconfig not found @tsconfig/node24/tsconfig.json.

Note

Medium Risk
Changes clone URL selection for provider-based clones, which can affect how private repos authenticate (HTTPS vs SSH). Explicit protocol and URL clones stay the same.

Overview
Create & Clone no longer hardcodes SSH. Looked-up repos now clone with protocol: "auto" so GitHub’s per-host gh config git_protocol can choose HTTPS vs SSH.

GitHub lookup reads gh config get git_protocol --host <host> and attaches optional preferredProtocol. Auto clones use SSH only when that preference is ssh; otherwise they use HTTPS (including when config is missing). Explicit HTTPS/SSH and raw clone URLs are unchanged.

Note

Honor configured git_protocol for automatic repository clones

• GitHubCli.Service.getRepositoryCloneUrls now runs an extra gh config get git_protocol --host <host> lookup and attaches preferredProtocol ("ssh" | "https") to the returned clone URLs. Errors during this step are tolerated.
• selectRemoteUrl changes automatic protocol selection: SSH is only chosen when preferredProtocol is explicitly "ssh"; otherwise HTTPS is used. Explicit "ssh"/"https" branches are unchanged.
• The Command Palette UI defaults looked-up repositories to the HTTPS URL and routes cloning through the new getCloneSourceInput helper with protocol: "auto".
• Contracts in sourceControl.ts add an optional preferredProtocol field to SourceControlRepositoryCloneUrls and SourceControlRepositoryInfo.
• Behavioral Change: automatic cloning now prefers HTTPS instead of SSH unless the provider's gh config explicitly sets git_protocol to SSH for the host. Review selectRemoteUrl in SourceControlRepositoryService.ts.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR introduces new runtime behavior by querying gh config for protocol preferences and changing how clone URLs are selected (previously defaulted to SSH, now uses configured preference with HTTPS fallback). New feature functionality affecting clone operations warrants human review.
