refactor: Unify Karma tsconfigs

[mondoreale]

This pull request updates TypeScript configuration files related to testing, mainly by centralizing the configuration of type definitions for Karma tests. The main change is moving the specification of test-related type definitions from individual package-level tsconfig.karma.json files into the root tsconfig.karma.json, simplifying and unifying the configuration across packages.

Changes

Centralization and simplification of test type definitions:

• The root tsconfig.karma.json now includes all necessary test-related type definitions (jest, jest-extended, and @streamr/test-utils/customMatcherTypes) in its types array, ensuring consistent type support for tests across all packages.
• The display field in the root tsconfig.karma.json was updated to use a hyphen instead of an en dash for consistency.

Cleanup of package-level configurations:

• Removed the types arrays from the tsconfig.karma.json files in packages/dht, packages/proto-rpc, packages/trackerless-network, and packages/utils, as these are now inherited from the root config. [1] [2] [3]

Other minor updates:

• The root tsconfig.karma.json now only includes the latest ECMAScript and DOM libraries in its lib array, removing older versions for clarity and modernity¹.

Footnotes

1. lib field is cumulative – including ESNext (bleeding edge) means we implicitly include all previous. ↩

Pull request overview

This PR refactors TypeScript configuration for Karma browser tests by centralizing test-related type definitions in the root tsconfig.karma.json. Previously, each package maintained its own list of test type definitions, leading to inconsistency. Now all packages inherit a unified set of types (jest, jest-extended, and @streamr/test-utils/customMatcherTypes) from the root configuration.

Key changes:

• Centralized test type definitions in root tsconfig.karma.json to ensure consistency across all packages
• Simplified package-level configurations by removing redundant types arrays that now inherit from root
• Cleaned up the root config by removing redundant ES library versions (ESNext implicitly includes all previous versions) and fixing the display field punctuation
