claude-wrapper should launch claude via caffineate

[twistedmelonman]

right now the system can go to sleep in the middle of a long-running CCCLI session.

if we launch claude via caffineate, the system will stay awawke for the duration of the claude process.

I aplogize for my atrocious spelling.

Fixed in 7757005 (#125). The wrapper now execs claude through caffeinate -i, which holds a PreventUserIdleSystemSleep assertion for the life of the session and releases it on exit.

The Closes #121 keyword was present in the squash commit but did not fire automatically, so closing manually.
