chore(deploy): roll out LayerSwapFacet v1.0.0 to production (39 networks)

[gvladika]

Which Linear task belongs to this PR?

https://linear.app/lifi-linear/issue/EXSC-220/sc-deploy-sc-to-production (EXSC-220)

Why did I implement it this way?

Production rollout of LayerSwapFacet v1.0.0 (audited 2026-07-15, integrated in #1711).
Each production LiFiDiamond gets the facet via CREATE3 deploy + a timelock-wrapped
diamondCut Safe proposal (one per chain). All 39 proposals have been signed, executed
after the timelock delay, and confirmed on-chain. script/deploy/_targetState.json lists
LayerSwapFacet 1.0.0 for the deployed networks, and each <chain>.diamond.json facet
registry has been regenerated from on-chain state now that the cuts executed.

Production proposals (39 networks)

Not in this PR (follow-up)

• zkSync-family — abstract, sophon, zksync: need DeployLayerSwapFacet.zksync.s.sol (+ zksolc build) before deploy.
• hyperevm — deploy tx exceeds the chain's block gas limit; needs chain-specific gas handling.
• swellchain — configured RPC returns HTTP 401; needs a valid ETH_NODE_URI_SWELLCHAIN.

Walkthrough

LayerSwapFacet addresses, diamond facet metadata, and version 1.0.0 mappings were added across supported network deployment configurations. Existing facet addresses remain unchanged except for the specified BSC facet replacements and two DiamondCutFacet version updates.

Changes

LayerSwapFacet registration

Layer / File(s)	Summary
Deployment address manifests deployments/*.json	Adds LayerSwapFacet contract-address entries across supported network deployment files while preserving existing mappings.
Diamond facet configurations deployments/*.diamond.json	Registers LayerSwapFacet with address, name, and version metadata, reorders periphery keys, and updates the specified BSC, Lisk, and Worldchain facet mappings.
Production target-state version maps script/deploy/_targetState.json	Adds LayerSwapFacet: "1.0.0" to production LiFiDiamond facet maps across supported networks.

Estimated code review effort: 3 (Moderate) | ~25 minutes
