Add searchable registry names

[charlesHetterich]

Summary

• adds OrderedIndex-backed package-name search to the registry contract
• wires frontend search to the registry searchContractNames query, with paginated results and a reusable search box on the search page
• fixes redeploying packages against fresh registry deployments by scoping package salts to the registry address
• avoids dry-running dependent deployment layers before prior layers have been registered
• points presets/templates at the redeployed Paseo registry

Release

Includes a changeset for patch bumps to @dotdm/contracts, @dotdm/env, and @dotdm/utils. Changesets also reports patch bumps for internal dependents @dotdm/cli and @dotdm/cdm; the CLI is private but the release workflow uses its version for GitHub release binaries.
