refactor(memory): simplify memory flush counter

CHANGELOG.md

 - Docs/Docker: document a local Compose override for Docker Desktop DNS failures in the shared-network `openclaw-cli` sidecar, keeping the default compose setup hardened while unblocking `openclaw plugins install` when users opt in. Fixes #79018. Thanks @Jason-Vaughan.
 - Installer: when npm installs `openclaw` outside the parent shell PATH, print follow-up commands with the resolved binary path instead of telling users to run `openclaw` from a shell that will report `command not found`. Fixes #72382. Thanks @jbob762.
 - Plugins/runtime: share MIME and JSON Schema helpers across bundled plugins while preserving canonical media MIME inference, browser URL wildcard semantics, migration home-path resolution, QA request-limit responses, and extensionless text file previews.
-- Agents/memory flush: persist the pre-increment compaction counter after flush-triggered compaction so consecutive eligible compaction cycles run memoryFlush instead of alternating. Fixes #12590; carries forward #51421 and refs #12760, #26145, and #46513. Thanks @Kaspre, @lailoo, @drvoss, @Br1an67, and @dial481.
