Adds a [pipeline] block: an ordered sequence of DISTINCT agents (different prompt/model/dir) run one
at a time, advancing when each writes its completion marker — the standalone-agent analog of the
[loop] phase machine (which drives FIXED loop agents via ## DONE). The watchdog reconciles it every
tick, stateless (markers are the source of truth): exactly the first not-yet-complete stage runs,
earlier stages are retired, the active stage is stall/heal-watched. Pipeline agents are enabled=false
(the pipeline owns their lifecycle).
Also fixes a latent watchdog crash: wake_elapsed is built once at startup but config is re-read each
tick, so removing an agent's 'wake' mid-run (e.g. winding down a wake) hit agent['wake'] -> KeyError
and killed the whole watchdog silently (stalling phase advancement + stall recovery). Now skips agents
whose wake was removed.
IDEAS.md: note that [pipeline] and [loop].phases are the same shape and should be unified via an
optional per-phase agent/dir/done (fold pipeline into the phase machine, delete the parallel path).
