Function hooks_block 

pub fn hooks_block(workflow: Workflow) -> String

The hook block for one workflow mode, authored as blocks/pre-commit-block.yaml.in with the worktree mode’s guard entry beside it in blocks/pre-commit-worktree-guard.yaml.in.

Markers included, without a trailing newline and with its scope token unrendered. What is landed is what runs: the worktree mode’s block carries the location guard and names the sweep-skip pair, and the branches mode’s block carries no guard entry at all — never an entry that reads local state to decide whether to enforce. The one branch grammar substitutes here from BRANCH_GRAMMAR.
