chore(ci): add dependency checks and reorganize tangled dependencies

[gagik]

This adds a dep check using knip. We use depcheck in Compass but this is deprecated and knip is recommend instead. This adds a basic configuration and then uses it to untangle some of our dependencies. This includes:

• Moving dependencies into dev dependencies, most notably mongodb! which we actually only use for types in the code itself at the moment.
• Moving certain types, consts into helper utils as they are only relevant there.

This seems like a useful feature and allows us to avoid mixing up our scripting or testing code with production.

Pull Request Overview

This PR introduces dependency management improvements using knip for dependency checking and reorganizes dependencies to better separate production code from development/testing code.

• Adds knip configuration and dependency checking to the CI pipeline
• Moves production-only types and utilities like mongodb from dependencies to devDependencies
• Relocates test-specific types and utilities to a dedicated test utils module

tests/accuracy/sdk/matcher.ts:1

• The removal of PARAMETER_SCORER_SYMBOL appears to be removing unused code, but this should be verified with test coverage to ensure this symbol is truly unused across the accuracy testing framework.

const MATCHER_SYMBOL = Symbol("match");

tests/accuracy/sdk/constants.ts:1

• The removal of TEST_DATA_DUMPS_DIR constant should be verified to ensure it's not used elsewhere in the accuracy testing framework, as this could break test data loading functionality.

Ah, it seems trouble figuring out bash scripts... So some deps need to be re-added

FYI: for knip ! means it's a production code it treats it differently then entry points files (i.e. that's how it complains about something being a dependency instead of a dev dependency)

[gagik]

correct me if I'm wrong but I don't think we were using devtools-connect anywhere...

I think it's a transitive dependency of the mongosh service-provider-node-driver. We can get rid of it here.
