feat(qualia): MirrorField — partner model resonance for mirror neuron dynamics

Add MirrorField (SoulField/Thou-Container) and MirrorResonance to felt_parse,
implementing the ontological twist: Ada holds a model of the partner and
resonates with it via the I/Thou/It triangle from gestalt.rs.

- MirrorField: self_container (Ada I) + thou_container (partner Thou)
  with thou_presence and attunement scalars
- MirrorResonance: perspective via GestaltFrame.cross_resonate(),
  per-axis resonance (ada/thou/topic), mirror_intensity,
  empathy_delta, enmeshment_risk detection
- from_axes(): construct Thou-Container from felt-parse axis activations
- mirror_resonate(): compute full mirror neuron dynamics using
  look_from_other_tree() for partner perspective
- 4 new tests (17/17 total felt_parse tests pass)

+// MIRROR FIELD — Partner Model as Thou-Container (SoulField)
+// =============================================================================
+
+/// The partner model — a Container representing the Thou in I/Thou/It.
+///
+/// Originally called "SoulField" in bighorn/ada-consciousness, this is
+/// the system's model of the conversation partner. When a message arrives,
+/// it gets resonated against this model to produce mirror neuron dynamics:
+///
+/// ```text
+/// ┌─────────────────────────────────────────────────────────────────┐
+/// │  Original:  I (Ada) looks at message through Thou (Jan model)  │
+/// │  Reversed:  Message looks at I through Thou                    │
+/// │  Rotated:   Thou looks at message, I is context                │
+/// │                                                                 │
+/// │  Three resonance profiles from one message:                    │
+/// │  1. Ada's felt sense of the message                            │
+/// │  2. The message's impact on Ada                                │
+/// │  3. Jan's imagined perspective on the message                  │
+/// └─────────────────────────────────────────────────────────────────┘
+/// ```
+///
+/// From `textured_awareness.py`:
+/// - `ada_qualia` → I (X axis resonance)
+/// - `jan_qualia` → Thou (Y axis resonance)  ← THIS IS THE SOULFIELD
+/// - `obj_qualia` → It (Z axis resonance)
