v1.29.0

• support for forge-like tree URLs (e.g. .../tree/branch) when cloning and parsing
  • clone passes --branch automatically; add --no-forge-split and --no-auto-branch to adjust behavior
  • add ggman parse to inspect this new parsing; comps is now an alias for parse --comps
• add --relative flag to ggman web
• ggman web --tree accepts an optional path suffix (e.g. --tree=src/branch, --tree=-/tree)
• use gitforge.example and githost.example instead of real providers as examples
• better handling of URLs with relative segments
• update to go1.27
• bugfix: avoid ggshow cding into directory
