Improve gh start-up time #9724
Description
Context
In #9686, it was reported that gh start-up time could be improved.
In #9686 (comment), it was discovered that a factor causing slow gh start-up time is related to tcell's init process, and that setting TCELL_MINIMIZE=1 to bypass that process could improve gh start-up time.
This issue is to investigate and identify any other factors involved in a less than optimal gh start-up time and provide a recommendation of what can be done to improve the situation
Expected output
- An investigation into factors slowing down
ghstart-up time - A recommendation on the work required to reduce
ghstart-up time

Before I forget, the existing attempt to set
TCELL_MINIMIZEis just not going to consistently work:cli/internal/build/build.go

The issue is that
initfunctions are executed deepest first, with different import branches having no guarantees between them. Thus, the only way to havetcellinitrun after ourinitwould be to have a direct dependency on our init fromtcelli.e. forking it. At least that's the only way I can think of it working.
