refactor(core)!: rename Provider to LLMProvider and update implementations

Browse Source 
- Export `LLMProvider` from `owlen-core` and replace public `Provider` re-exports.
- Convert `OllamaProvider` to implement the new `LLMProvider` trait with associated future types.
- Adjust imports and trait bounds in `remote_client.rs` to use the updated types.
- Add comprehensive provider interface tests (`provider_interface.rs`) verifying router routing and provider registry model listing with `MockProvider`.
- Align dependency versions across workspace crates by switching to workspace-managed versions.
- Extend CI (`.woodpecker.yml`) with a dedicated test step and generate coverage reports.
- Update architecture documentation to reflect the new provider abstraction.

## Crate Breakdown
- `owlen-core`: Defines the core traits and data structures, like `Provider` and `Session`. Also contains the MCP client implementation.
- `owlen-tui`: Contains all the logic for the terminal user interface, including event handling and rendering.
- `owlen-cli`: The command-line entry point, responsible for parsing arguments and starting the TUI.
- `owlen-mcp-llm-server`: MCP server that wraps Ollama providers and exposes them via the Model Context Protocol.
- `owlen-core`: Defines the `LLMProvider` abstraction, routing, configuration, session state, encryption, and the MCP client layer. This crate is UI-agnostic and must not depend on concrete providers, terminals, or blocking I/O.
- `owlen-tui`: Hosts all terminal UI behaviour (event loop, rendering, input modes) while delegating business logic and provider access back to `owlen-core`.
- `owlen-cli`: Small entry point that parses command-line options, resolves configuration, selects providers, and launches either the TUI or headless agent flows by calling into `owlen-core`.
- `owlen-mcp-llm-server`: Runs concrete providers (e.g., Ollama) behind an MCP boundary, exposing them as `generate_text` tools. This crate owns provider-specific wiring and process sandboxing.
- `owlen-mcp-server`: Generic MCP server for file operations and resource management.
- `owlen-ollama`: Direct Ollama provider implementation (legacy, used only by MCP servers).
### Boundary Guidelines
- **owlen-core**: The dependency ceiling for most crates. Keep it free of terminal logic, CLIs, or provider-specific HTTP clients. New features should expose traits or data types here and let other crates supply concrete implementations.
- **owlen-cli**: Only orchestrates startup/shutdown. Avoid adding business logic; when a new command needs behaviour, implement it in `owlen-core` or another library crate and invoke it from the CLI.
- **owlen-mcp-llm-server**: The only crate that should directly talk to Ollama (or other provider processes). TUI/CLI code communicates with providers exclusively through MCP clients in `owlen-core`.
## MCP Architecture (Phase 10)
As of Phase 10, OWLEN uses a **MCP-only architecture** where all LLM interactions go through the Model Context Protocol:
