chore: update default values for parser limits

[devsergiy]

Summary by CodeRabbit

• New Features
  • Increased the default parser depth limit from 100 to 200.
  • Increased the default total fields limit from 500 to 3500.

These changes enable improved handling of deeper and more complex data parsing by default.

Walkthrough

The default values for parser limit configurations were increased in both the Go configuration struct and its associated JSON schema. The ApproximateDepthLimit was raised from 100 to 200, and TotalFieldsLimit from 500 to 3500. Corresponding test configuration files were updated to reflect these new defaults. No other fields or logic were modified.

Changes

Cohort / File(s)	Change Summary
Parser Limits Default Value Update router/pkg/config/config.go, router/pkg/config/config.schema.json	Increased default values for ApproximateDepthLimit (100→200) and TotalFieldsLimit (500→3500) in both Go struct and JSON schema.
Test Configuration Updates router/pkg/config/testdata/config_defaults.json, router/pkg/config/testdata/config_full.json	Updated test configuration files to reflect increased default values for ApproximateDepthLimit and TotalFieldsLimit.
