Bump git-manager plugin to 1.1.0

Backward-compatible feature addition (raw-git nudge hook, tag subcommand,
repo-ambiguity guidance in SKILL.md). Bumping per ARCHITECTURE.md's
documented convention, and because the plugin cache path is version-keyed
(~/.claude/plugins/cache/skill-repo/git-manager/<version>/), so a bump is
also what makes /plugin marketplace update reliably pick up the change.
