justin d435384b58 #2 (framework): bi-directional / service-function engine 
Profile-defined UDS action sequences, run safely -- the framework for #2 (real
per-vehicle actuator tests/resets are follow-on, added as verified profile data).

- obdcore/actions.py: Action model + run_action() executing session (Mode 10) ->
  security (Mode 27 seed->key) -> command steps (2F/31/11/3E/... any hex) with
  positive/negative response checks. Security KEY algorithms are per-vehicle
  secrets and NOT bundled -- only trivial transforms (xor-ff/invert/add-ff)
  known; an action naming an unknown algorithm is BLOCKED (fails safe). Never
  synthesizes bytes -- runs only what the profile defines. validate_action()
  rejects malformed hex at load.
- profile.py: load/save an actions[] block; ElmLink/MockLink read_raw(hex).
- GUI: Diagnostics -> Service & Bi-directional dialog -- lists the profile's
  actions with risk badges; caution/danger gated behind a warning confirmation.
- generic-obd2: two safe STANDARD actions (Tester-Present ping; ECU-Reset,
  caution + engine-off warning). PROFILE_SPEC.md documents the actions schema
  + safety rules.
- tests/test_actions.py: runner, session+reset, security handshake, unknown-algo
  block, hex validation, profile load. All 5 suites pass.

justin 03223dfd6c Rename project to OBDash + per-metric colored multi-axis 
Rename: the app is vehicle-agnostic, so 'ford-obd' was wrong. Rebranded all
code/docs/profile authors to OBDash; Gitea repo renamed justin/ford-obd ->
justin/obdash (remote + description updated). Ford the make and the
ford-6.0-powerstroke profile are unchanged (that vehicle really is a Ford).

Multi-axis upgrade (per request):
- MultiAxisPlot now gives each METRIC its own Y axis, each axis colored to
  match its line; the primary metric owns the LEFT axis, others stack right.
- Click a line to promote it to the left axis (sigClicked -> set_primary).
- Cleaner teardown (no removeItem warnings); axis label no longer doubles the
  unit; Normalize round-trips.

Validated headless: colored per-metric axes, promote-to-left, gauge view,
normalize toggle, profile switch; obdcore + diagnostics tests 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.
