Terminal scroll bar annotations #144595
Description
We want to add monaco-style annotations to the terminal, some example uses:
- Show where commands are run with their exit status
- Find decorations Terminal Find: Highlight all instances of term in current viewport and don't manipulate selection #134790
- Potentially also calling out problems from problem matchers? Haven't thought about this much
Unknowns:
- It seems like this would cause an awfully noisy scroll bar if many small commands are run
