feat(mimo): add ai-mimo launcher for Xiaomi MiMo V2.6 Pro

ai-mimo runs Claude Code through Xiaomi's Anthropic-compatible API
(Token Plan or pay-as-you-go). The key's endpoint is found by probing
token-plan-sgp, token-plan-ams and api.xiaomimimo.com (a key only works
in its own region) and is saved to mimo_base_url; MIMO_BASE_URL
overrides. Unreachable endpoints are skipped, token-plan-cn is left out
of the probe since it times out from our network, and a 402 on the
pay-as-you-go endpoint explains that a tp- Token Plan key is needed.

Always the smartest model: mimo-v2.6-pro in every slot and for
subagents, --model opus and --effort max on each start, 128000 output
tokens (Claude Code's ceiling), real 1M context window. Measured on
13.10: MiMo ignores output_config.effort (even "bogus" is accepted, no
length trend from low to max) and treats thinking adaptive like
enabled, so reasoning is always on; EFFORT_MAPPING.md records this.

/logout-mimo is registered as a command and handled by the logout hook
(removes mimo_key and mimo_base_url). setup.sh status, statusline brand
color, README, QUICK_START and AGENTS.md list the new launcher.
