chore: drop HANDROLLED sentinel machinery from context-sync.sh

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.
