fix(amazonq): handle explain, refactor, fix, optimize, sendToPrompt (aws#7169)

## Problem
explain, refactor, fix, optimize right click menus aren't working

## Solution
re-enable them through flare's genericCommand message

## TODO
- handle generateUnitTests
- handle explainIssue
both of these need flare API changes to send generic prompts from the
frontend to the backend
