[computer use] replace spaces in api_key when starting loop

[bmacer]

this addresses #85.

it would seem that if multiple users have already encountered this, maybe the propensity to copy-paste with a trailing space is common enough to address.

maybe not the most graceful solution, just replaces all spaces when the sampling_loop begins.

prior to the fix, here's the error when i use an API key with a trailing space:

after the fix, no problem, even with a trailing space:

[marco-altran]

I can still reproduce #85 after your fix (yes, I applied your fix and did the build locally).

I also experimented with disabling the cache prompt and increasing image_truncation_threshold. The issue takes longer to appear, but eventually, after a minute, the error persists. I hardcoded the API key, and nothing changed, so I am ruling out API key issues.

My hunch is either malformation of messages or the Anthropic API not handling a specific situation.
