defiQUG 01e0779a3d 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

# Fund all CCIP WETH9/WETH10 bridge contracts with LINK on each chain.
# Amount via tag (not .env): --link <amount> (default 10 LINK), --dry-run to print commands only.
# --cap-to-deployer: per chain, each bridge gets min(--link, deployer_LINK_balance // bridges_on_chain).
# Usage: ./scripts/deployment/fund-ccip-bridges-with-link.sh [--link 10] [--cap-to-deployer] [--dry-run]
