Fix #39: memos add 成功但立即 get/list 查不到；且不存在 memos list 子命令

[Memtensor-AI]

Description

Fixes issue #39 — the memos add / memos get race and the missing memos list command. memos add printed "memory added" while the server was still asynchronously extracting/storing, so a follow-up memos get frequently returned empty results. memos list was referenced in MemOS CLI.md and skill docs but never registered in main.py.

Fix: (1) Registered memos list as an alias of memos get (same callback, same options, same output). (2) Added --wait / --no-wait (default --wait) and --wait-timeout (default 30s) options to memos add; when a task_id is present in the add response and status is "running", the CLI now polls /get/status until the task reaches a terminal state or the timeout elapses. (3) Rewrote the add success formatter to surface task_id and reflect the true final state (Memory added on completed, "still processing" hint on timeout, "accepted; task_id=..." on --no-wait, Memory add failed on terminal failure). (4) Updated README.md and README-zh.md to document the new options and the list alias.

Verification: full unit-test suite passes (56 tests, +15 new in tests/test_memory_add_wait.py) covering task_id extraction, polling until completion, --no-wait skipping polling, timeout guard, typer wiring, list-alias registration, and all four output branches. Manual memos --help, memos add --help, and memos list --help output confirmed. The change is a strict superset of the old contract — responses without a task_id fall back to the original behaviour, so servers that don't return an async id are unaffected.
