such a small nit, but the agents are annoyed: we reference mySequence[3] but then give a len == 3 sequence so thats an out of bounds.

this was never fully completed, so we currently reject them in all [maybe most?] cases

| Live Debugger uses logpoints: auto-expiring, non-breaking breakpoints that collect diagnostic data without pausing the application. Since execution continues normally, Live Debugger can be used safely on production systems to investigate problems as they happen. | ||

| Live Debugger complements [Dynamic Instrumentation][38], which adds metrics, spans, and span tags using the same [expression language][15]. |

@timsee To improve the agent's understanding of DI vs. LD, does the explanation need to be in the intro section? Or could we have a dedicated section lower on the page with a more detailed explanation of how they overlap and differ?

yeah, lets move out of the intro do a dedicated section, thats a great idea!

Working on a draft for this, will add a comment here when ready.

| Dynamic Instrumentation lets you add metrics, spans, and span tags to running production systems without restarts or code changes, including in third-party libraries. | ||

Same comment as on the LD doc - we can duplicate the same copy on both pages if the docs team is okay with it.

What does this PR do? What is the motivation?
We've had a lot of product decisions around live debugger and dynamic instrumentation, but havent formalized them in external docs. Changes in here are mainly around:
Five English documentation pages only. The scrubbing page moves under Live Debugger with redirects from its old URLs. Simulator code and test changes are deferred.
