[nodejs] Add live debugger guardrail fixtures

[watson]

Motivation

The Node.js tracer guardrail work for DEBUG-6081 needs matching system-test fixtures and stable inputs for its budget and timeout behavior.

Changes

• add the /debugger/budgets/:loops fixture to the Node.js Express, TypeScript Express, and Fastify weblogs
• add the Node.js source-line mapping used by line-probe budget tests
• increase the collection-filter input so optimized runtimes reliably exceed the evaluation budget
• update the shifted capture-timeout line mapping and endpoint documentation

Testing

Tested with the Node.js tracer stack tip watson/DEBUG-6081/evaluation-timeout pinned at b1d7c6c5ef3393214c7095afe65885933d44e046.

• DEBUGGER_PROBES_SNAPSHOT: 4 passed
  • line-probe budgets
  • line-probe capture-expression budgets
  • regex evaluation timeout
  • collection-filter evaluation timeout
• DEBUGGER_CAPTURE_TIMEOUT: 1 passed
