128K context window

crucible-1 now supports 128,000 token context, doubled from 64,000.

This covers the full length of most documents without chunking:

• Standard commercial agreement: 8-15K tokens

• Full quarterly earnings report: 40-70K tokens

• Regulatory filing: 90-120K tokens

No integration changes required. If you have been chunking documents to work within the 64K limit, you can remove that step. crucible-1-mini remains at 32K tokens.
