feat(opencode): add JSON-only integration and compact AGENTS.md generator (#570)

* feat: add OpenCode integration implementation plan for BMAD-METHOD

* installer(opencode): add OpenCode target metadata in install.config.yaml

* chore(deps): add comment-json for JSONC parsing in OpenCode integration

* feat(installer/opencode): implement setupOpenCode with minimal instructions merge and BMAD-managed agents/commands

* feat(installer): add OpenCode (SST) to IDE selector and CLI --ide help

* fix(opencode): align generated opencode.json(c) with schema (instructions as strings; agent.prompt; command.template; remove unsupported fields)

* feat(installer): enhance OpenCode setup with agent selection and prefix options

* fix: update configuration file references from `bmad-core/core-config.yaml` to `.bmad-core/core-config.yaml` across multiple agent and task files for consistency and clarity.

* refactor: streamline OpenCode configuration prompts and normalize instruction paths for agents and tasks

* feat: add tools property to agent definitions for enhanced functionality. Otherwise opencode consders the subagents as readonly

* feat: add extraction of 'whenToUse'  from agents markdown files for improved agent configuration in opencode

* feat: enhance task purpose extraction from markdown files with improved parsing and cleanup logic

* feat: add collision warnings for non-BMAD-managed agent and command keys during setup

* feat: generate and update AGENTS.md for OpenCode integration with agent and task details

* feat: add compact AGENTS.md generator and JSON-only integration for OpenCode

* chore(docs): remove completed OpenCode integration implementation plans

* feat: enable default prefixes for agent and command keys to avoid collisions

* fix: remove unnecessary line breaks in 'whenToUse' descriptions for QA agents to mathc the rest of the agents definitions and improve programatic parsing of whenToUse prop

* fix: update OpenCode references to remove 'SST' for consistency across documentation and configuration

* fix: update agent mode from 'subagent' to 'all' for consistency in agent definitions

* fix: consolidate 'whenToUse' description format for clarity and consistent parsing
