Slice (c) of the R3 build-out: a `schedule` CLI verb (print-first launchd
plist / cron-table line) + `run-daily.sh`, a bash-3.2 headless wrapper that
runs the DETERMINISTIC morning brief from a profile-less scheduler env.
Closes hulls #1 (no autonomous trigger) + #6 (no headless entry point).
Operator-confirmed (AskUserQuestion 2026-06-26): C1 deterministic brief-only
(no AI capture — that is slice e, which plugs into the documented pre-brief
seam); C2 print-first installer (the tool emits the artifact + the install
command; `--install` writes only the inert launchd plist file; never runs the
scheduler activation itself).
Light-Voyage hardened — three Opus reviewers, each verifying against live
code: scope-guardian ALIGNED (0 creep/0 gaps), brief-reviewer
PROCEED_WITH_RISKS, plan-critic REVISE. All findings folded, incl. the
pretty-printed `brief --json` log-line compaction, the `cd "$DIR"` cron fix,
the logPath base pinned to `dirname(defaultStorePath())`, the canonical
`ScheduleSpec.env`, and the `ASSERT_BASELINE_FLOOR` :1259->:1329 cite. No
schema/count change (29/19/27, store v4). Tracked feature-design.
