Alex eb10a511f0 ci(smoke): sanitizer build + module/interaction/a11y/layout coverage
Turn the smoke test into a real runtime safety net. Waybar is now built with
AddressSanitizer and exercised end to end in a headless compositor:

- Tier 0: run everything under ASan; fail on ASan reports and Gtk/GLib
  criticals in the log (lib.sh assert_clean)
- Tier 1: per-module render matrix (modules.sh) — each headless-safe module
  rendered in isolation
- Tier 2: pointer interaction (interact.sh) — inject clicks via sway, assert
  on-click side effect and format-alt toggle; AT-SPI assertions (a11y.sh/.py)
  check module labels semantically instead of by pixels
- Tier 3: layout matrix (positions.sh) — top/bottom/left + HiDPI scale 2;
  second compositor run under labwc

Shared helpers extracted to lib.sh. Adds a workflow_dispatch `bless` input to
regenerate the golden reference in one click. Trigger push only on master to
avoid duplicate PR runs. AT-SPI and labwc steps are continue-on-error.
