This is largely a cleanup PR, removing unused or unnecessary code, refining interfaces, removing internal functions from public API, and making logging more verbose. no real functional changes. Net negative lines of code.

Summary

• Change loadDwJson() to return {config, path} for proper path tracking in DwJsonSource
• Make internal utilities internal (remove mapDwJsonToNormalizedConfig, mergeConfigsWithProtection, getPopulatedFields from public exports)
• Remove deprecated sources option from ResolveConfigOptions
• CLI commands now use ResolvedB2CConfig directly with .values.* access pattern
• SDK command classes use factory methods (createB2CInstance(), createMrtAuth(), etc.) instead of manual construction
• Fix replaceDefaultSources option to work without requiring sourcesAfter
• Adds verbose trace logging to ConfigSource's so we know where config is coming from and what they contrib.

Bug Fix: account-manager-host from dw.json ignored

Fixed an issue where account-manager-host configured in dw.json was being ignored. The oclif flag had a default value that was always passed as an override to config resolution, preventing dw.json values from being used. Removed the default from the flag definition and rely on the existing fallback in the accountManagerHost getter.

Structured Logging Improvements

Improved structured logging across the SDK to ensure log calls have proper structured fields for machine-parseable output while preserving human-readable messages:

Pattern Applied

// Before (anemic - values only in message):
logger.warn(`Job ${jobId} already running`);

// After (proper structured + readable):
logger.warn({jobId}, `Job ${jobId} already running`);

Files Updated

• Auth: api-key.ts, basic.ts, oauth.ts, oauth-implicit.ts - Added auth-specific fields (headerName, keyPreview, username, port, duration)
• Operations: jobs/run.ts, jobs/site-archive.ts, code/deploy.ts, code/versions.ts, code/watch.ts - Added domain-specific fields (jobId, executionId, codeVersionId, cartridgeName, path)
• Clients: middleware.ts, webdav.ts - Added HTTP fields (method, url, status, duration)

Key Changes

• Use B2C-specific keys for domain objects (jobId not id, codeVersionId not version)
• Use simple keys for general-purpose domains (path, method, url, server)
• Changed reserved Pino field hostname to server in watch.ts

Breaking Changes

• loadConfig() now returns ResolvedB2CConfig instead of NormalizedConfig
• Access config values via .values.* property (e.g., this.resolvedConfig.values.hostname)
• ResolvedConfig type alias removed from exports
• Internal mapping utilities no longer exported

Test plan

• All SDK tests pass (83 tests)
• All CLI tests pass (83 tests)
• Build succeeds for all packages
• Manual test with dw.json configuration
