gcontext 0.12.1

Added

• Command control: commands.yaml with a disabled list lets you hide any command by its stable key (e.g. browser-cookbook/browse)
• shares and configurable fields in the agent manifest, with validation on install and share
• Dashboard agents tab and /api/agents endpoint
• Startup log shows how many commands are disabled

Changed

• Connection scaffolding reports missing kinds instead of creating stub folders
• Update flow is ownership-aware: learned directories are skipped, configurable files backed up as .pre-update, example runs skipped when real runs exist

Fixed

• Hash comparison strips injected base-path comments so check/update reports match the registry
