chore: consolidate code analysis rules and update dependencies (#1102)

## 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

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