Adds BugSplat.hang() backed by a native infinite loop (jniHang) so the
ANR thread dump includes a symbolicated C++ frame, enabling end-to-end
testing of the symbolication pipeline against .sym files.

Updates the example app's Trigger ANR button to call BugSplat.hang()
instead of a Java busy-loop.

Documents the new ANR detection feature (Android 11+), including how it
works, configuration, testing with BugSplat.hang(), and the Android 11+
requirement. Also updates the example app feature list to mention the
ANR trigger button and custom attribute dialog.

Loads bugsplat.database, bugsplat.clientId, and bugsplat.clientSecret
from the gitignored local.properties instead of hardcoding them in
example/build.gradle. Fails the build with a clear error if
bugsplat.database is not configured.

Also switches bugsplatAppName and bugsplatAppVersion to be derived from
android.defaultConfig.applicationId and versionName respectively, so
there's a single source of truth for these values.

The per-ABI uploadBugSplatSymbols{BuildType}{Abi} tasks didn't declare
a dependency on the merge${BuildType}NativeLibs task that produces
merged_native_libs/. If the upload task ran before packageDebug (e.g.
when passed alongside installDebug on the command line), the native
libs directory didn't exist yet and the upload was silently skipped.

Adding dependsOn merge${BuildType}NativeLibs ensures the native libs
are always in place before the upload runs.

AGP 8.6 changed the intermediates layout to include the producing task
name in the path:
  old: merged_native_libs/{buildType}/out/lib/{abi}/
  new: merged_native_libs/{buildType}/merge{BuildType}NativeLibs/out/lib/{abi}/

Replaces the shared uploadBugSplatSymbols task (which used
System.setProperty for buildType/abi, making it racy and Gradle-dedupe
unsafe) with a proper per-ABI approach:

- Extract upload logic into uploadSymbolsForAbi(buildType, abi) and
  resolveSymbolUploadExecutable() closures.
- Each per-ABI task has its own doLast body that calls the helper
  with explicit parameters — no more System.setProperty.
- AllAbis chains the per-ABI tasks with mustRunAfter so they run
  serially. The symbol-upload binary uses a shared temp dir, so
  parallel invocations aren't safe.
- Delete the legacy uploadBugSplatSymbols task entirely.

Fixes: AllAbis previously only uploaded one ABI due to Gradle
deduplicating the shared task dependency.

Replace the stale Gradle example that showed hardcoded credentials in
ext{} with the local.properties approach. Adds notes on:

- AGP 8.6+ intermediate path layout
- Serial vs parallel execution (symbol-upload's shared temp dir)
- ABI-filter-aware skipping for single-ABI builds (e.g. AS running on
  a single-ABI emulator)

CI doesn't have a local.properties, so the top-level bugsplat.database
check was failing the build. Adds resolution order:
  local.properties → -Pbugsplat.database=... → BUGSPLAT_DATABASE env var

Both CI workflows (Tests, CodeQL) now pass BUGSPLAT_DATABASE=fred.

AnrReporter:
- Only advance last_reported_anr_timestamp when upload succeeds so
  transient failures don't permanently skip the affected ANRs.
- Process ANRs oldest-first (reverse the newest-first list from
  getHistoricalProcessExitReasons) and break on failure so newer
  ANRs are retried next launch without masking an older failure.
- Shut down the one-shot executor after submitting the check so the
  worker thread doesn't linger.

ReportUploader:
- Fix FileInputStream leak in upload(File, ...) with try-with-resources.
- URL-encode query string params in getCrashUploadUrl.
- Use UTF-8 explicitly in readBody() and all multipart byte writes.
- Accept any 2xx from S3 PUT (not just 200).
- Add upload(Map<String, byte[]>, crashType, id) overload for
  multi-entry zips, plus matching createZip(Map) helper.

FeedbackClient:
- Restore attachment upload — attachments are now packed as real zip
  entries alongside feedback.txt, not just logged as filenames in the
  text report. This fixes a behavioral regression from the previous
  multipart feedback POST.

Example app:
- Move the "Trigger ANR" button label into strings.xml for i18n.

Tests:
- Clean up dead code in TestableReportUploader trailing-slash handling.
- Update feedback attachment test to verify the new behavior (zip entry)
  rather than the old (name logged in feedback.txt).

Adds a new 'Loading config from local.properties' section under Usage,
and updates all init/postFeedback examples to reference
BuildConfig.BUGSPLAT_DATABASE / APP_NAME / APP_VERSION instead of
hardcoding 'fred' / 'my-app' / '1.0.0'.

The same bugsplat.database value is reused by the symbol upload task,
so there's now a single source of truth across runtime and build.

Also adds a 'Custom Attributes' subsection under User Feedback showing
how to pass the new attributes Map parameter.
