chore: consolidate code analysis rules and update dependencies

[dluc]

Summary

This PR consolidates code analysis configuration and updates dependencies:

• Removed temporary analyzer configuration files that were used during development (src/Core/.editorconfig, src/Core/GlobalSuppressions.cs)
• Consolidated code analysis rules into main .editorconfig with pragmatic severity levels
• Updated dependencies: Spectre.Console (0.49.1 → 0.54.0/0.53.1), YamlDotNet (16.2.0 → 16.3.0)
• Fixed CLI command signatures to match updated Spectre.Console API (added CancellationToken parameter)
• Applied code quality fixes including culture-aware string formatting

Changes

Configuration

• Removed temporary src/Core/.editorconfig and src/Core/GlobalSuppressions.cs files
• Consolidated all analyzer rules into main src/.editorconfig
• Disabled overly strict analyzer rules that conflicted with project patterns:
  • CA1031 (catch general exceptions) - needed for top-level error handling
  • CA1859 (concrete return types) - visitor pattern requires base types
  • RCS1141 (param documentation) - reduced noise during development
  • RCS1211 (unnecessary else) - style preference
  • CA1307/CA1308 - intentional string comparison behavior

Dependencies

• Spectre.Console: 0.49.1 → 0.54.0
• Spectre.Console.Cli: 0.49.1 → 0.53.1
• YamlDotNet: 16.2.0 → 16.3.0

Code Fixes

• Added CancellationToken parameter to all CLI command ExecuteAsync methods (breaking API change in Spectre.Console)
• Added CultureInfo.CurrentCulture to ToString() call in MongoJsonQueryParser.cs:325
• Updated using statements and removed redundant suppressions
• General code style improvements

Test Plan

• build.sh passes with 0 warnings/errors
• format.sh passes
• coverage.sh passes with 83.82% coverage (threshold 80%)
• All 503 tests pass (289 Core + 214 Main)
• Zero skipped tests
