Tolerate cached Lab dependency fetch failures

[chubes4]

Summary

• Allow clean rig dependencies to continue snapshotting when git fetch fails but the checkout still matches its cached upstream tracking ref.
• Preserve hard failures for stale or diverged dependencies so Lab does not silently run old code.
• Add regression coverage for unreachable remotes with cached-up-to-date checkouts.

Tests

• cargo fmt --check
• cargo test core::runner::git_dependency_materialization
• cargo build

AI assistance

• AI assistance: Yes
• Tool(s): OpenCode (GPT-5.5)
• Used for: Diagnosing the private dependency fetch failure, drafting the narrow fallback and regression test, and running verification. Chris remains responsible for review and validation.
