feat: add --verbose flag to Claude invocation for observability

[ItzikEzra-rh]

Adds --verbose to the Claude CLI command so detailed progress (tool calls, thinking, phase transitions) goes to stderr, which is already captured to session.log via the existing tee on line 48.

No change to stdout or the cli-output.json parsing.
