Resolve skill repository versions over Git transport - #21

Add the Git transport layer of repository-versioned skill management:
querying refs and fetching snapshots through git instead of the GitHub
Releases, Tags, or Commits REST APIs, so the same code path supports
GitHub, GitHub Enterprise, and other Git hosts without REST quotas.
- ResolveVersion locks a user-supplied spec to an immutable version:
"latest" (or an omitted version) selects the highest stable SemVer
tag via ls-remote, falling back to the default branch's full HEAD
SHA when the repository has no stable SemVer tags; a branch or
short commit resolves to the full commit SHA; a prerelease tag is
selected only when named explicitly.
- fetchSnapshot shallow-fetches one tag or commit into a directory
and strips Git metadata, with a full-history fallback for hosts
that refuse fetching by SHA.
- Private repositories reuse whatever authentication Git already
has (SSH agent, credential helpers, .netrc, insteadOf rules);
prompts are disabled and stderr is credential-sanitized before it
is attached to errors.
Integration tests run against local fixture repositories routed
through Git insteadOf rules, which also exercises the design's claim
that local Git configuration chooses the transport. Adds
golang.org/x/mod for SemVer comparison.
