Add transaction, balance, and API gap commands

[cameroncooper]

Summary

• Adds transaction, balance, asset, offer, CLVM, and inspect-oriented CLI coverage for Coinset APIs.
• Adds missing Coinset API gap commands for push_offer and get_reorgs, including pretty reorg output.
• Extends websocket events filtering with direction, offer, status, and p2 filters, and shares pretty-output request plumbing.

Test plan

• go build ./...
• go vet ./...
• coinset push_offer -h
• coinset get_reorgs -h
• coinset events -h
• coinset get_reorgs --limit 500 rejects invalid limit
• coinset get_reorgs --pretty --raw rejects incompatible flags
• coinset get_reorgs --limit 5 --pretty verified against mainnet
