chore(build): Avoid prebuilding api side, instead use an esbuild plug…

…in (#9767)

Resurrecting this again, to see if I can get CI more stable this time 

**2nd edition Implementation:** With the second edition, I'm trying
esbuild's watcher - rather than chokidar
This is a no go ❌, because when new files are introduced the watcher
isn't triggered.

**3rd edition implementation**: Use esbuild's `rebuild` function that
_may_ provide performance benefits

Old PR #7672
