sourceDir now defaults to the bundled framework/ directory instead of
mosaicHome, so syncFramework() actually copies files. Additionally,
syncFramework() now copies root-level defaults (AGENTS.md, STANDARDS.md,
etc.) from framework/defaults/ into mosaicHome when they don't already
exist. Bump to 0.0.9.
