v0.6.1

Fixed

• Bundle naming: directory bundles use the directory name (e.g. local-bundle for ./local-bundle); git bundles use @owner/repo from repo root, and @owner/repo/bundle-name or @owner/repo:path/from/root for subdirectories, matching the bundle spec
• Bundle resolution: config and lockfile are found correctly (augent.lock in . or ./.augent); names written to augent.yaml and augent.lock are consistent with the chosen source
• Git bundles are served from cache when possible — repeated installs of the same ref no longer refetch
• Cache stores one entry per repo+sha instead of per sub-bundle, so multi-bundle repos use a single copy instead of duplicates
