LongProbe v0.1.2

[mohsin1218]

Key Additions & Enhancements:
🧪 Pytest Integration (@golden_check):

Introduced the @golden_check decorator for writing inline, sub-second RAG regression tests directly inside existing test suites.
Added configuration auto-discovery (longprobe.yaml) with support for session-level longprobe_adapter fixture overrides.
🔍 Retrieval Diagnostic Tool (longprobe explain):

Added a troubleshooting CLI command to analyze regressions.
Detects "interloper" chunks that pushed down expected content and runs extended searches to find exactly where missing chunks shifted in rank.
🖥️ Interactive Terminal Editor (longprobe edit):

Built a terminal-native, dual-pane Textual TUI to interactively manage golden questions.
Supports creating, deleting, and updating questions, tags, top_k, and match modes directly from the terminal (Ctrl+S, Ctrl+N, Ctrl+D).
📚 Enterprise-First Documentation:

Realigned guides to favor the production-grade HTTP Adapter as the default recommendation (supporting any API or LongTrainer backend).
Promoted Qdrant as the primary direct-database adapter example, moving ChromaDB to a local prototyping footnote.
📦 Release Packaging:

Added the [tui] optional dependency group to pyproject.toml.
Bumped package version to 0.1.2 across the entire codebase.
