Sync marketplace.json versions with plugin.json for all 14 touched
plugins. Fix plugin.json versions for llm-application-dev (2.0.3),
startup-business-analyst (1.0.4), and ui-design (1.0.2) to match
marketplace lineage. Add dotnet-contribution to marketplace.
Rewrites 14 commands across 11 plugins to remove all cross-plugin
subagent_type references (e.g., "unit-testing::test-automator"), which
break when plugins are installed standalone. Each command now uses only
local bundled agents or general-purpose with role context in the prompt.
All rewritten commands follow conductor-style patterns:
- CRITICAL BEHAVIORAL RULES with strong directives
- State files for session tracking and resume support
- Phase checkpoints requiring explicit user approval
- File-based context passing between steps
Also fixes 4 plugin.json files missing version/license fields and adds
plugin.json for dotnet-contribution.
Closes#433
