v0.2.0

v0.2.0 — Full Extension SDK

Extension API

• mc.exit() — exit the CLI
• mc.newSession() — start fresh session
• mc.getCwd() / mc.getModel() / mc.setModel() — session control
• mc.sendMessage() / mc.sendUserMessage() — inject messages
• mc.exec(command) — run shell commands, returns stdout/stderr/exitCode
• mc.showWarning() — shorthand for warning messages
• mc.clearScreen() — clear TUI history
• mc.state.get/set — persistent key-value storage per extension

Lifecycle events

• sessionEnd, toolExecutionStart, toolExecutionEnd

Fixes

• Extension commands now reliably show in autocomplete
• Host waits for ready signal before proceeding
• Error isolation — bad extensions don't crash the host
