fix(executor): isolate CLAUDE_CODE_TMPDIR for nested claude to fix (no output) (#154)

* fix(executor): isolate CLAUDE_CODE_TMPDIR for nested claude to fix (no output)

Claude 2.1.45+ calls Nz7() in preAction to clean its tasks directory on
startup. When claude runs as a nested subprocess, it deletes the parent
session's *.output files, causing the parent to read an empty string and
display "(no output)".

Fix: assign each nested claude process its own unique CLAUDE_CODE_TMPDIR
(os.TempDir()/cc-nested-<pid>-<ns>) so it only cleans its own tasks
directory and never touches the parent's output files.

* fix(executor): use MkdirTemp for nested tmpdir
