pub fn install_claude_md_guidance(
project_dir: &Path,
sqz_path: &str,
) -> Result<bool>Expand description
Install sqz’s guidance block into CLAUDE.md at project_dir.
If CLAUDE.md doesn’t exist yet, create it with a minimal preamble
and sqz’s block. If it exists, append sqz’s block (separated by a
blank line so it renders as a new markdown section). If the block
is already present (detected by the BEGIN sentinel), it is replaced
in place when it differs from this version’s block for sqz_path,
and the file is left alone otherwise, so sqz init stays idempotent.
Returns true when the file was created or modified, false when
sqz’s current block was already present.
