fix: set MiniMax-M3 default context to 1m

MiniMax's official M3 model page and release notes describe M3 as supporting up to a 1M-token context window with a guaranteed minimum of 512K. Keep the built-in MiniMax preset aligned with that official default instead of inheriting the older 204.8K MiniMax generation limit.

Constraint: Official MiniMax M3 docs state the M3 API supports up to 1M tokens context window.
Rejected: Keep 204800 and rely on manual provider overrides | that makes the built-in MiniMax preset wrong for new users.
Confidence: high
Scope-risk: narrow
Directive: Do not copy MiniMax-M2.7's 204.8K window onto MiniMax-M3 without re-checking official M3 docs.
