/**
 * `peaks compact *` — strategic-compact CLI primitives.
 *
 * top-level `peaks compact` group:
 *
 *   - suggest:    PreToolUse-style two-signal suggestion (context size
 *                 + tool-call count), read-only by default.
 *   - recommend:  Pure (from, to) phase-pair → severity lookup.
 *   - survival:   Static SKILL.md "What Survives Compaction" table.
 *   - dry-run:    Composite of (suggest + recommend + survival), no
 *                 writes.
 *   - force:      Write a pre-compact checkpoint via
 *                 `peaks session checkpoint`; the IDE-side `/compact`
 *                 is still the LLM's call.
 *   - history / harness-window / settle: the observability and hook
 *                 transport for the window this group reports on.
 *
 * Each subcommand returns a `--json` envelope via `printResult`. This module is
 * the registrar: the parent group is created here and handed to each command's
 * own module.
