refactor(claude-code): move module_directory to $HOME/.coder-modules/claude-code

Follow the shared convention proposed in #782 for
stable per-module persistent storage. coder-utils threads this value
through into the generated pre_install, install, and post_install
wrapper scripts, so scripts and logs now live at
$HOME/.coder-modules/claude-code/ instead of $HOME/.claude-module/.

Namespacing under $HOME/.coder-modules/ keeps $HOME from getting
polluted with one dotdir per module when a workspace uses several,
and matches what boundary, tasks, and agentapi are standardizing on.

Updates the README troubleshooting block and the 8 log-path
expectations in the bun test suite to match.

Related to #782.
