docs: release beta.156 documentation sync

[deucebucket]

Summary

• release the documentation and MIT-license synchronization as beta.156
• update the README version badge and recent changes
• include llama.cpp and OpenAI-compatible servers throughout provider guidance
• correct Skaldleita credential and request-rate documentation
• record the documentation synchronization in the changelog

Why

The beta.155 provider implementation was merged, but several current documentation and help-text locations still described beta.153, omitted the generic provider, or listed retired rate limits. Repository CI requires a version bump because configuration/help Python modules changed.

Validation

• test-env/test-naming-issues.py (290 passed)
• test-env/test-ai-providers.py (11 passed)
• test-env/test-ai-provider-integration.py (4 passed)
• python -m compileall -q app.py library_manager
• git diff --check
• added-line scans for credential-shaped values and AI attribution
• GitHub lint, test, version-check, and container-build jobs passed

Context

Documentation synchronization PR updating version badges, provider lists, rate limit defaults, and Skaldleita credential guidance to match beta.155 behavior.

Codebase Patterns I Verified

• Documentation style: Project uses markdown docs with tables, code blocks, and clear section headers (verified in docs/Configuration.md, docs/FAQ.md)
• Provider terminology: References "Skaldleita" alongside Audnexus, OpenLibrary, Google Books, Hardcover (verified in library_manager/hints.py layer_1 hint)
• Config comments: config.py uses inline comments to explain optional fields (verified pattern in DEFAULT_SECRETS)
• Version badge format: README uses shields.io badge pattern pointing to CHANGELOG.md

✅ Good

• Focused scope: Only documentation and hint text changes, no logic modifications
• Consistent terminology: Updated references to include "OpenAI-compatible" provider alongside Gemini, OpenRouter, Ollama
• Accurate rate limit docs: Changed from "2000 calls/hour" to "200 requests/hour with range 10-500" which matches config.py:142 ("max_requests_per_hour": 200)
• Proper credential guidance: Updated bookdb_api_key comment from "not required for public endpoints" to "bundled shared key is used when empty" — aligns with beta.155's authenticated endpoint changes noted in CHANGELOG

Context

Documentation-only PR synchronizing version numbers, provider lists, and configuration guidance with the current beta.156 state.

Codebase Patterns I Verified

• Versioning: app.py contains APP_VERSION = "0.9.0-beta.155" which is updated to 0.9.0-beta.156 in the diff.
• Provider Naming: The codebase uses "Skaldleita" as the primary brand name (e.g., library_manager/hints.py hint 'skaldleita': 'Free GPU-powered audio identification service...'), while bookdb is used internally for the API client (library_manager/providers/bookdb.py).
• Rate Limiting: library_manager/config.py shows "max_requests_per_hour": 200 as the default.
• AI Providers: library_manager/hints.py lists gemini, openrouter, ollama, and the new openai_compatible key.

✅ Good

• Consistency: Version badges in README.md and app.py are correctly synchronized to 0.9.0-beta.156.
• Accuracy: Rate limit documentation in docs/Configuration.md now correctly reflects the code's default of 200 requests/hour (previously documented as 2000, which would have been dangerous).
• Clarity: library_manager/hints.py updates accurately describe the openai_compatible provider and the shared Skaldleita credential behavior.
• Scope: Changes are strictly limited to documentation and version strings; no logic changes detected.
