refactor(types)!: drop support for Node <26

[favna]

This is a type-only breaking change that raises the minimum supported Node version to 26. The update aligns the error inspection types with the Node util package change from InspectOptionsStylized to InspectContext, so consumers on @types/node below 26 will now hit type errors when upgrading to this major.

Changes

• Updated the custom error inspection signatures across the error hierarchy to use InspectContext.
• Adjusted the BaseError unit test to match the new Node 26 inspect type.
• Bumped the package engine requirement to Node 26 and refreshed the Yarn/tooling metadata.

Testing

• Updated the error test coverage to compile against the new inspect type.
• No runtime behavior changes were introduced; this is a types-only compatibility break.

Breaking Change

• Minimum supported Node version is now 26.
• Projects pinned to @types/node below 26 must upgrade before adopting this release.
