* fix(runner): surface focus-tap errors in InputText action
A failed Tap/TapSelector before InputText was swallowed, so text typed
into the wrong field (or no field) still reported success. Return the
error so the step fails explicitly.
* feat(sample-app): add username EditText and snapshot
Gives the spec a real EditText target (content-desc: username_field)
so the InputText action path can be exercised end-to-end. The typed
value is mirrored into MainActivity.username and surfaced as the
"username" snapshot for spec assertions.
* feat(sample-app): exercise InputText action against username field
Adds typeUsername action and usernameNeverShrinks property to the
sample spec, and extends the integration test to assert the bundled
spec emits an InputText(desc:username_field, "alice") action and that
the property correctly violates when a snapshot reports a shorter
string.
interestingTags hardcoded selectors from a specific app (etMobileNumber,
customer_row_, supplier_row_, etc.) inside the generic runner. None of
these selectors exist in the checked-in sample spec. Debug log now just
reports screen + hierarchy size; specs that want richer visibility can
log from state.ax.find themselves.
Removes Launch + Terminate from runner.Run so the CLI can launch
the app first, wait for the SDK to connect, then start the loop.
The previous shape forced runner to launch internally which fought
with the SDK-must-be-connected-first ordering.
BundleID/ClearState fields go away too since runner no longer
launches; the CLI keeps them on its testOptions struct.
Wires agent.Conn + driver.Driver + verifier.Verifier + trace.Writer
into the v0.1 step cycle: snapshot the SDK, push to verifier,
evaluate properties, write the trace step (with violations), release
the SDK pause, apply the next action via the driver, wait for idle.
Driver.Launch happens once before the loop and Terminate runs in
defer so even an early error tears down the app cleanly. Summary
returns step count and per-step violation records for the caller
to print or persist.
