Review N1 (planner-reviewer-claude-01 50ae9fb0, planner-reviewer-codex-01
8779f4b4): af8a54c (R1) stopped reusing an idle pane when env flags are
present, because the old path put `env K=V ...` after `herdr agent start ...
--`, where herdr passes it to the agent executable as arguments. h25 still
required that old behaviour (idle pane reused, env in the agent command) and
failed. It now asserts the new contract instead: a pane split / workspace
create carries MY_TEST_FLAG=active and HERDR_WORKSPACE_ID as --env, the agent
does not land on the idle pane, and nothing env-like follows `--` in agent
start. Finding A's intent (env must not be silently lost) is kept; reuse
without env flags stays pinned by h24. No product code changes.
