docs: clarify OPENCLAW_MEMORY_DIR for memory browser

OpenClaw does not create a memory/ subdirectory under OPENCLAW_HOME.
Agent memory markdown files (daily logs, MEMORY.md, etc.) live in each
agent's workspace directory, not in ~/.openclaw/memory/.

Without OPENCLAW_MEMORY_DIR set, the memory browser falls back to
OPENCLAW_HOME, which only contains .sqlite session indices — not the
human-readable markdown files users expect to see.

Document the correct value and add an inline note to .env.example.
