Release v0.13.1

UI Enhancement - Replace dialoguer with inquire + Commit Message Cleaning

Migrates all interactive prompts from dialoguer to inquire for a better terminal UX. Also adds automatic stripping of markdown code block fences from LLM-generated commit messages and optimizes the release binary size.

Changed

Interactive Prompt Library Migration

• Replaced dialoguer with inquire 0.9 for all interactive prompts (Select, Confirm, Text)
• Affected modules: commit action menu, split action menu, config edit menu, retry feedback input, confirm dialog
• Error type renamed from GcopError::Dialoguer to GcopError::Inquire

Commit Message Cleaning

• New clean_commit_response() strips markdown code block fences (```, ```text, ```markdown) from LLM responses
• Applied in both streaming and non-streaming commit generation paths
• 9 unit tests added for fence stripping edge cases

Build Optimization

• Release opt-level changed from "s" (size) to "z" (aggressive size) for smaller binaries
• config crate: disabled default features, only toml feature enabled
• rustls: removed logging feature
