feat(ccip): cap LINK funding to deployer balance per chain; fix Arbitrum gas
- parse_link_tags: add --cap-to-deployer for fund-ccip-bridges-with-link.sh - fund-ccip: min(target, balance//bridges) per chain; reuse one wei for both bridges under cap so post-transfer balance does not undershoot the second send - Arbitrum: append legacy --gas-price from RPC (3x) with floor to clear base fee Co-authored-by: Cursor <cursoragent@cursor.com>
