## What changed
- the-matrix/js/agents.js fully rewritten with face expression system
## Face geometry
- Replaced flat dark-blue eye spheres with white sclera (MeshStandardMaterial,
emissive 0x777777@0.10, roughness 0.55) + dark pupils (MeshBasicMaterial 0x07070f)
as child meshes of sclera
- Eyes are now children of the head mesh (not the group) so they naturally
follow head.rotation.z tilts driven by the existing animation loop
- Mouth added as a canvas Sprite (128x32, always faces camera) parented to the
group so it bobs with Timmy's body; drawn via quadraticCurveTo bezier arc
## Emotion → face parameter mapping (FACE_TARGETS table)
- idle (contemplative): lidScale=0.44, smileAmount=0.08 — half-lid, neutral
- active (curious): lidScale=0.92, smileAmount=0.38 — wide eyes, smile
- thinking (focused): lidScale=0.30, smileAmount=-0.06 — squint, flat mouth
- working (attentive): lidScale=0.22, smileAmount=0.18 — very squint, slight grin
## Per-frame lerp (updateAgents)
- faceParams lerped toward faceTarget at rate 0.055/frame (smooth, no snap)
- eyeL.scale.y / eyeR.scale.y driven by faceParams.lidScale (squash = squint)
- Mouth canvas redrawn only when |smileDelta| > 0.016 or speakingChanged
(avoids unnecessary texture uploads every frame)
## Lip-sync while speaking
- While speechTimer > 0: smileTarget = 0.28 + sin(t*6.283)*0.22 (~1 Hz)
- _drawMouth() renders two-lip "open mouth" shape when speaking=true
- Returns to mood expression when speechTimer expires
## Validation
- Vite build: clean (14 modules, 529 kB bundle, no errors)
- testkit: 27/27 PASS (no regressions)
- No out-of-scope changes (backend untouched)
Implement session-based API endpoints for creating, managing, and interacting with pre-funded sessions, including deposit and top-up invoice generation, macaroon authentication, and per-request debiting of compute costs.

Refactor TIMMY_TEST_PLAN.md and timmy_test.sh to support dual-mode payments (per-job and session-based). Add new tests for session endpoints and gracefully handle rate limiting in existing tests.

Integrates a new bash script for automated end-to-end testing of the Timmy API. Updates API routes to expose payment hashes in stub mode for easier invoice payment simulation during testing. Modifies test plan documentation to include the new automated script.
