justin f2308cd4eb P2: true multi-axis overlay + gauge view 
gui/widgets.py:
- MultiAxisPlot -- overlay with one Y axis PER UNIT (psi/V/rpm/C/%), linked
  ViewBoxes on X, so mixed-scale signals are readable at true values
  (base left axis + up to 4 right axes).
- SinglePlot -- one shared axis for the Normalize (% of range) mode.
- ArcGauge -- 270deg arc gauge with peak tick + numeric readout, own dark bg.
- GaugeGrid -- scrollable grid of gauges.

gui/main.py:
- Graph page is now a multi-axis/single-axis sub-stack; Normalize toggles
  between true multi-axis (raw) and single-axis (%). curves map key->color;
  plot ops route to the active graph widget.
- Gauge View menu enabled (3rd center page); gauges update on tick with peak.
- Theme applies to both plot widgets; profile switch clears graphs/gauges.

Fix: ArcGauge QPen built via setCapStyle (the QPen(...cap=...) kwarg segfaults
PySide6). Validated headless: driving preset -> 6 unit groups across 5 axes,
gauge view renders, normalize round-trips, profile-switch clears cleanly.
obdcore + diagnostics tests still pass.

justin f3f0bf2a77 Make app vehicle-agnostic: JSON vehicle profiles + menu bar 
Vehicle data is now DATA, not code. PIDs/scaling/DTCs/presets live in
profiles/*.json; the app loads them at runtime, so it works across vehicles
and others can contribute profiles (open source).

Core:
- obdcore/formula.py: safe AST evaluator for scaling formulas (A/B/... byte
  vars, Torque/FORScan convention). Only arithmetic/bitwise + min/max/abs/
  round/int/float; names/attrs/arbitrary calls rejected at load -> a community
  profile CANNOT execute code.
- obdcore/profile.py: load/save/list profiles; compiles each formula into a
  decode callable. registry.py now profile-backed (PidRegistry/DtcDatabase
  take a Profile); hardcoded Ford table removed.
- store.py: clear()/snapshot()/export_csv() for capture management.

Profiles:
- profiles/ford-6.0-powerstroke.json (27 PIDs, verified formulas, DTCs)
- profiles/generic-obd2.json (standard SAE Mode-01 base, any vehicle)
- profiles/README.md (schema + formula language + contributing)

GUI:
- Menu bar: File (new/record/export/replay capture, quit), Profile (switch/
  load/import/reload/edit-JSON/export, live profile list), View (Graph/Table
  views, gauges P2, toggle PID dock, normalize, light/dark theme), Help
  (about/confidence legend/profile info).
- PID browser + presets rebuild on profile switch; added Table view; raw-JSON
  profile editor dialog (validates schema+formulas before saving).

Tests: profiles load+compile, formula sandbox rejects hostile input, decoders
still match real truck bytes, crank/derived/dead-PID/replay -- all pass.

justin 4589904b97 P1: PySide6 + pyqtgraph GUI shell (PID browser + live overlay plot) 
First graphical frontend on obdcore. Cross-platform (Win/mac/Linux).

- gui/controller.py: owns link/registry/store/scheduler; subscribe == poll ==
  plot; per-PID rates (ICP/FICM/RPM fast); optional CSV recording.
- gui/main.py: connection bar (port dropdown via find_ports, baud, Mock,
  connect), left PID browser grouped by system with live values + confidence
  badges + checkboxes, central pyqtgraph overlay plot with legend, Normalize
  (% of range) toggle for mixed-scale PIDs, Crank/Driving/Vitals presets,
  10Hz refresh reading the store off the acquisition thread.
- run_gui.py launcher; requirements-gui.txt.
- store.py: lock Channel push/series (GUI reads while scheduler writes).
- docs/gui-p1-preview.png: validated render (mock crank, ICP ramp to 540).

Validated headless (offscreen Qt): connect(mock) -> crank preset -> ICP
streams past 500 -> normalize -> uncheck removes curve -> clean disconnect.
obdcore tests still pass after the locking change.
