    LIF: 100x | ROLE: INHERITANCE_RELAY

    Siphons genetic truth from the Daemon's `GrandSurveyor`.
    It maps:
    - Scaffold Traits -> Parents/Children
    - Python Classes -> Parents/Children
    - TypeScript Interfaces -> Implements/Extends

    ### THE 12 ASCENSIONS:
    1.  **Symbol Divination:** Extracts the type symbol under cursor.
    2.  **Context Injection:** Embeds `file_path` and `symbol_id` into `data`.
    3.  **Trace Integrity:** Propagates `trace_id`.
    4.  **Titanium Pathing:** Uses `UriUtils` for absolute parity.
    5.  **Null Guarding:** Handles empty Daemon responses.
    6.  **Kind Mapping:** Maps Daemon kinds to `SymbolKind` enums.
    7.  **Root Anchoring:** Sends project root for relative resolution.
    8.  **Synchronous Relay:** Uses `relay_request` with timeout protection.
    9.  **Model Transmutation:** Converts raw dicts to Pydantic models.
    10. **Recursive Safety:** Daemon handles cycle detection.
    11. **Polyglot Support:** Generic enough for any language the Daemon supports.
    12. **Forensic Logging:** Detailed error reporting.
