Nothing in the workspace uses the HANDROLLED escape hatch anymore — the
infra repo (its only consumer) was migrated to the standard pattern.
Removing the dead code: HANDROLLED_MARKER constant, skip_if_handrolled
function, and call sites in each generator. Sync output for any non-
HANDROLLED file (i.e., every file we have) is unchanged.

Phase 4 sweep updated .gitignore and Taskfile.yml but missed this
script. Copy the canonical from ~/dev/project-template/ so the
HANDROLLED escape hatch works in this project (a CLAUDE.md or
adapter file containing '<!-- HANDROLLED: do not regenerate -->'
near the top is now skipped on regeneration).
