Add member directory tab to home navigation (#3)

* feat(healthchat): add member directory tab to home navigation Third bottom-nav tab backed by the HealthChat API: searchable member cards with native start-chat, approval-pending banner, retry on failure and navigation into the native profile screens. * fix(healthchat): stop tab back handler swallowing back presses While a screen is pushed on top of Home, the still-composed tab BackHandler intercepted back presses during the transition and invisibly switched to the Chats tab. Gate it on the node's target visibility in both the parent and Home's own backstack. * fix(healthchat): satisfy detekt, ktlint and konsist rules Import alias order, composable parameter order in HomeView, and konsist presenter helper shape. * ci: pass the real repository name to the screenshot recorder recordScreenshots.yml set GITHUB_REPOSITORY from `secrets.GITHUB_REPOSITORY`. No such secret exists on this fork, so the expression expands to an empty string and overrides the built-in environment variable of the same name. recordScreenshots.sh checks it up front and exits 1 with "No repo specified", so the workflow could never record anything here. Use the `github.repository` context instead, which is always populated. Claude-Session: https://claude.ai/code/session_01MQbp1EPM4TSXq8P8Pyq44F * Update screenshots * Revert "Update screenshots" This reverts commit b99e0d643f. * Reapply "Update screenshots" This reverts commit 85bceb6d67. * test(screenshots): stop a LayoutLib teardown crash failing the shard tests Paparazzi 2.0.0-alpha05 / LayoutLib 16.2.1 races on HandlerThread startup: HandlerThread_Delegate.run calls Process.setThreadPriority, which throws NoSuchMethodError for Thread.setPosixNicenessInternal and kills the "android.bg" thread. If the test thread reaches getLooper() after that, it gets null, BackgroundThread.ensureThreadReady() NPEs, and the static initialiser of LatencyTracker fails. The JVM then marks that class erroneous for the lifetime of the fork, so every later preview showing the soft keyboard dies with NoClassDefFoundError. LayoutLibErrorFilterStatement already swallowed the bare NoSuchMethodError, but PaparazziLogger re-throws collected background errors from teardown() wrapped in a MultipleFailuresException when there is more than one, and that wrapper slipped through. A recent run reported 17 failures with zero image comparisons failing and zero delta images written. Unwrap the wrapper by reflection and swallow it only when every collected cause matches the known-bug list; anything unrecognised, and anything that cannot be decomposed, is rethrown. Also close a hole this filter had from the start. Paparazzi runs the test as `try { body } finally { teardown() }`, so a teardown error discards whatever the body threw — including a genuine snapshot mismatch. renderFailureCapture is registered inside the Paparazzi rule to record the body's exception so it wins over any teardown error, and the filter refuses to swallow anything if that rule is not registered. Two HorizontalFloatingToolbar previews have been mismatching silently behind this, and may now surface as real failures.
