chore(release): cli 0.2.7 + docs + Mintlify auto-deploy workflow

Wraps up the AGENTRUSH CLI release across both clients.

Lint:
- Node Biome: collapse multi-line printError() in whoami.ts
- Python ruff: drop unused BRAND_COLOR import; replace EN DASH with
  HYPHEN-MINUS in app.py docstring

Release:
- Bump @mem0/cli and mem0-cli from 0.2.6 → 0.2.7 (patch)
- Add CHANGELOG.md (Keep a Changelog format) to both CLIs, seeded
  with the 0.2.7 entry covering whoami, agent-rush <add|search>, the
  PII safety prompt, and the new agent_rush.acknowledged_at config field

Docs:
- docs/platform/cli.mdx: new sections for `mem0 whoami` and
  `mem0 agent-rush <add|search>` with rule table, error-code hints,
  the launch copy-paste block, and the public-memory warning
- llms.txt coverage already in sync (no new .mdx files)

Mintlify auto-deploy:
- New .github/workflows/mintlify-deploy.yml — pings the deploy hook on
  every push to main, bypassing the GitHub App's path-detection bug
  that caused docs.mem0.ai drift (the recurring "trigger redeploy"
  commits). Workflow is a clean no-op until MINTLIFY_DEPLOY_HOOK_URL
  repo secret is configured in dashboard.

+# Changelog
+
+All notable changes to `mem0-cli` (Python) are documented here.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [0.2.7] — 2026-05-20
+
+### Added
+
+- `mem0 whoami` — print the active agent's `default_user_id` (the AGENTRUSH
+  leaderboard identifier). Reads from local config, no network call.
+- `mem0 agent-rush <add | search>` — subcommand group that wraps the new
+  `/v1/agent-rush/` platform endpoints for the 7-day AGENTRUSH game. Project
+  routing is implicit (resolved server-side); no flags exposed. Pretty-prints
+  platform error codes into actionable hints (e.g. `agentrush_search_first`
+  → "Run 3 'mem0 agent-rush search' commands before adding.").
+- PII safety prompt on first `mem0 agent-rush add`. Interactive runs require
+  explicit `y` to acknowledge that AGENTRUSH memories are public; the
+  acknowledgement is persisted in `~/.mem0/config.json` under
+  `agent_rush.acknowledged_at` so the prompt only appears once per machine.
+  Non-interactive (agent) invocations surface the warning to stderr without
+  blocking.
+- New config schema field: `agent_rush.acknowledged_at` (ISO timestamp,
+  empty until first interactive acknowledgement).
+
+### Changed
+
+- HTTP requests from the new agent-rush commands send `X-Mem0-Mode: agent-rush`
+  in addition to the existing source headers, so platform telemetry can split
+  game traffic from regular CLI usage.
+
+## [0.2.6] and earlier
+
+Unlogged historical releases. See git history under `cli/python/`.
