feat: explore-minimax-run — read-only MiniMax exploration wrapper + mode guidance
Hardened wrapper for delegating broad codebase exploration to MiniMax M3:
per-root --add-dir scoping, secrets-root refusal, enforced read-only via
--disallowedTools (profile defaults to acceptEdits), JSON .result answer
channel, internal timeout + retry, file:line citation gate with distinct
fallback exit codes. deep/deep-fable/orch modes now prefer /explore-minimax
for broad read-only sweeps, Explore agent as fallback.
