Allow to specify permissions mode via environment variable

[beberlei]

I would like to run claude within ddev in bypass permisisons mode (equivalent of --dangerously-skip-permissions). This probably requires an environment variable to control the mode: https://code.claude.com/docs/en/permission-modes#skip-all-checks-with-bypasspermissions-mode

For now i fixed this by modifiying the generated command when the plugin was installed:

cat .ddev/commands/web/claude
#ddev-generated
#!/bin/bash

set -e

claude --dangerously-skip-permissions $@
