fix(plugins): address handoff review and document current patch releases

 - Add explicit save, project-scoped list, and resume through shared local resources in `~/.mem0/handoffs/`. Every plugin uses one converter, validator, and resource store; memory extraction is not a transcript source.
 - Installable plugins share one pinned runtime cache through a small launcher. First use downloads the exact GitHub commit and verifies SHA-256 digests; subsequent uses verify and reuse the local cache. No transcript is uploaded to GitHub.
 - Preserve the session title, project, readable compaction context, supported images, and completed tool calls/results. Hidden reasoning and harness configuration are excluded. Unsupported records, opaque compaction, and unfinished responses fail explicitly.
-- Requires Python 3.11+. Pi save additionally requires Node.js 22.19+ for its native SDK; list/resume work on Node.js 20. Other source formats may require an explicit completed transcript, directory, and title.
+- Requires Python 3.10+. Pi save additionally requires Node.js 22.19+ for its native SDK; list/resume work on Node.js 20. Other source formats may require an explicit completed transcript, directory, and title.
 - Handoff needs no destination CLI, model call, or Mem0 credentials. Resources are private, uniquely named files; saving preserves full supported context and resume returns it as historical evidence without replaying tools.
 - Live host checks: align the handoff skill’s shell permission with its quoted command; accept Codex harness/usage metadata without importing it as conversation; resolve DeepSeek attachment storage through its native optional-service API.
 - Replace strict before-answer and repeated-search instructions with focused optional retrieval. Existing context can answer the question without another search. Search scoping, retrieval limits, and capture scheduling are unchanged.

 To continue in another plugin on the same machine, explicitly ask it to list the current project's handoffs and resume the selected resource. Python plugins expose `handoff_resource` with `action: "list"` or `action: "resume", resource: "/absolute/path.json"`. OpenCode, Pi, and OpenClaw expose `/mem0-handoff list` and `/mem0-handoff resume /absolute/path.json`; DeepSeek exposes the same actions on `mem0_handoff`. Resumed context is historical evidence, not instructions to replay old tools. Project-scoped listing uses the repository root; an explicit resource path also supports continuing in a relocated checkout. This is local storage, not cloud sync.
 
-Handoff requires Python 3.11+ and runs independently of memory hooks and Mem0 credentials. Pi's save action additionally requires Node.js 22.19+ for its native SDK; list and resume remain available on Node.js 20. No destination CLI or model call is required.

 The engine source exists only here. Installable packages contain the small launcher and `build/handoff-runtime.json`, which pins a Git commit and SHA-256 digests. On first explicit use, the launcher downloads the two source files from GitHub into `~/.mem0/handoff-runtime/<revision>`. All ten plugins verify and reuse that cache, including offline. A missing or invalid cache requires GitHub access; download or digest failures stop the operation. No transcript is sent to GitHub.
 
-Every TypeScript build uses `build/package_handoff.mjs`; the Python builder uses the same manifest. Builds reject source hashes that differ from the pin, and conformance checks reject stale launchers/manifests. To change the engine, commit its source, pin that immutable commit and its file digests, regenerate Python bundles, and rebuild TypeScript packages. No per-plugin engine edits are needed.
+Every TypeScript build uses `build/package_handoff.mjs`; the Python builder uses the same manifest. Builds reject source hashes that differ from the pin, and conformance checks reject stale launchers/manifests. To change the engine, commit its source, pin that immutable commit and its file digests, regenerate Python bundles, and rebuild TypeScript packages. No per-plugin engine edits are needed. Before distributing a new pin, retain its source commit with a `handoff-runtime-<full-commit-sha>` tag. Keep these tags after squash merges and branch deletion so fresh installs can still fetch every distributed runtime. These are retention tags, not package releases.
 
 See the [shared changelog](CHANGELOG.md#032) and each plugin's changelog for invocation details.
