fix: add explicit wait-for-subagent instructions in orchestration workflows (#2755)

Adds ORCHESTRATOR RULE blockquotes immediately after every Task() spawn
in 26 GSD workflow files, instructing the parent orchestrator to stop
working on the task while the subagent is active. This prevents the
parallel-work anti-pattern on Codex runtime where the parent continues
reading files and producing duplicate/conflicting output after spawning.

Rules are placed inline at each spawn point (not as generic headers)
so they are adjacent to and unambiguously associated with each Task()
call. Background Task() spawns get a variant noting not to return to
the spawning context until the subagent reports back.

Closes #2729
