Fix pixi trampoline bug and defer claude download to first run

- Add conditional PATH entry for ~/.pixi/envs/claude-shim/bin to work
  around pixi trampoline bug that fails for bash script executables
- Remove claude --version calls during feature install to avoid
  downloading the Claude binary during container build
- Claude binary will now be downloaded on first user invocation
