v0.2.1 — One global component

Keep only dsh-compaction-policy/global. Remove legacy compatibility, old preset registration/list filtering, their exports, dependencies and tests.

The 90% native summary-first policy and output/reasoning settings are unchanged. Old experimental preset identities are no longer registered; no logs are deleted or rewritten.

Remove obsolete profile overrides for compaction-policy-legacy and compaction-policy-preset. Update through Desktop, then fully quit and reopen it.

Validation: 58 unit tests and 33 real-host synthetic tests passed; package contents contain no legacy/preset implementation.

v0.2.0 — Global 90% native compaction

Default installation now activates the global official-Basic adapter: 90% proactive pressure, native summary/checkpoint events, unchanged main output and reasoning settings, no special preset selection.

A hidden same-ID compatibility composition preserves v0.1 session restoration. Remove obsolete user profile overrides for compaction-policy-preset. Existing live v0.1 instances need natural restoration/restart; no logs are rewritten. Desktop-managed profiles must update through Desktop.

Validation: 63 unit tests and 38 real-host synthetic integration tests passed; Node 22/24 CI passed. Real GUI rendering and model summary quality are separate acceptance checks. Pinned to DSH 0.2.0-rc.2 and Cordis 4.0.4.
