* fix(ios): make `init_plugin_*` entry points public so release builds link on Xcode 27
Xcode 27's SwiftPM (Swift Build) gives non-public @_cdecl functions local
visibility in release builds, so each plugin's init_plugin_* is undefined
when Rust links. Mark them public in the 11 plugins with an iOS part.

* feat(shell): add process group spawn option (fix#1332)
Add a `processGroup` boolean option to the shell plugin's spawn command.
When enabled, the child process is spawned in its own process group (POSIX)
or job object (Windows) using the `process-wrap` crate, so that killing
the child also kills the entire process tree.
This fixes the issue where programs like PyInstaller wrappers spawn a
child process that gets orphaned when Tauri kills the parent.
* test(shell): add PyInstaller simulation tests for process group kill
Add end-to-end tests that reproduce the exact scenario from issue #1332:
a wrapper process (like PyInstaller's bootloader) spawns a grandchild.
- Without process_group: killing the wrapper orphans the grandchild
- With process_group: killing the wrapper also kills the grandchild
* refactor(shell): drop redundant cfg gates, trim process-wrap features
Address review feedback on #3351:
- Remove `#[cfg(any(unix, windows))]` gates on `ChildKind::ProcessGroup`,
the kill/pid match arms, and the spawn block, plus the now-dead
`#[cfg(not(any(unix, windows)))]` fallback. That cfg only excluded wasm,
which this plugin never builds for.
- Set `default-features = false` on process-wrap and enable only the
features actually used: std, process-group (unix), creation-flags and
job-object (windows). Drops kill-on-drop, process-session, and tracing.
* fix(shell): enable process-wrap tracing feature, fix CI formatting and changefile
- Add `tracing` feature to process-wrap: with default-features = false its
Windows job_object.rs calls `debug\!` unconditionally while the import is
gated behind `#[cfg(feature = "tracing")]`, failing the Windows build with
"cannot find macro `debug`".
- Reformat process/mod.rs assertions to satisfy `cargo fmt --check`.
- Reindent the process-wrap features array to 2 spaces for taplo.
- Use covector package keys (`shell` / `shell-js`) in the change file so the
check-change-files and covector status jobs pass.
* refactor(shell): unify child handling on process-wrap, drop SharedChild
Collapse the ChildKind enum and the per-platform GroupChild types into a
single process-wrap-backed child. The command always spawns through
StdCommandWrap; the process_group flag is now just an optional wrapper
rather than a switch into a separate child type.
This drops the shared_child dependency and resolves two review notes:
the Unix path no longer hand-rolls killpg, and kill() now goes through
process-wrap's kill (start_kill + wait), which reaps the entire process
group instead of only signalling it.
A background thread polls try_wait to surface the exit status, since
process-wrap's wrappers only expose &mut self wait methods (the reason
SharedChild was used on Unix in the first place).
* chore(example): add process group toggle to shell view
* fix(shell): pass typed creation flags to process-wrap on Windows
`process_wrap::std::CreationFlags` is a newtype over the `windows` crate's
`PROCESS_CREATION_FLAGS`, not a raw `u32`, so the Windows build failed to
compile. Depend on `windows` (already in the tree via `tauri`, pinned to the
same 0.61 that `process-wrap` links against) and use its `CREATE_NO_WINDOW`
constant, which drops the hand-rolled magic number.
The wrap is still required: `JobObject::pre_spawn` calls `creation_flags` and
would otherwise clobber the `CREATE_NO_WINDOW` set at construction.
* perf(shell): block on child exit instead of polling try_wait
The switch from `SharedChild` to `process-wrap` moved the child behind a
mutex, since `StdChildWrapper`'s wait methods take `&mut self` while both
the wait thread and `CommandChild::kill()` need access. A blocking wait
would hold the lock for the child's whole lifetime and starve `kill()`,
so the wait thread polled `try_wait` every 10ms instead.
Block on the raw process outside the lock using a wait that does not reap
(`waitid` with `WNOWAIT` on unix, `WaitForSingleObject` on windows), then
take the lock once to let process-wrap collect the exit status. This is
the same technique shared_child uses internally, applied on top of
process-wrap's kill/reap semantics. No new dependencies or Cargo features
are required.
`kill()` reaps the child while holding the lock, so the raw wait can lose
that race and return ECHILD. That means the exit status is already cached
in the wrapper, so it is treated as success and the status is collected
via `try_wait`. Without this guard, a stress test of 300 spawn+kill
cycles produced 36 Error events in place of Terminated; with it, none in
900 cycles. The `try_wait` loop stays as a defensive fallback, though in
practice the first call succeeds immediately.
Mean latency for `Command::output()` on macOS (debug, 30 iterations of
`echo`) drops from 13.22ms to ~1.8ms, and 10 idle 5s children cost ~11ms
CPU total instead of ~75ms with the poll loop.
* fix(shell): keep CREATE_NO_WINDOW on process-group children (windows)
process-wrap's CreationFlags/JobObject coordination is broken during
spawn (watchexec/process-wrap#35): JobObject::pre_spawn cannot see the
CreationFlags wrapper, so it overwrote our flags with just
CREATE_SUSPENDED and process-group children flashed a console window.
Register CreationFlags(CREATE_SUSPENDED | CREATE_NO_WINDOW) after
JobObject so its pre_spawn runs last and wins. CREATE_SUSPENDED is kept
so the child cannot spawn grandchildren before job assignment; the same
upstream bug keeps wrap_child's resume check from seeing it, so the
child is still resumed.
* test(shell): run the process-tree kill tests on windows
Add a powershell variant of the pyinstaller simulation script and lift
the unix-only gates on the process-group tests, so the windows job in
test-rust exercises the job-object spawn/kill path instead of skipping
it. Both pyinstaller tests now also assert that a Terminated event is
still delivered after kill().

* refactor(shell): replace process-wrap with shared_child and an inlined job object
Use std process groups on unix and a job object on windows, with
shared_child handling wait and kill on all platforms.
* fix(shell): kill the process group even after its leader exited
CommandChild::kill returned early once the direct child had been reaped,
so killpg/TerminateJobObject never ran and anything the child left running
in its process group or job object survived, including on app exit.
Adds a launcher-style test (the child starts a grandchild and exits) that
runs on Windows, Linux and macOS.
* fix(shell): restore Debug on CommandChild
Dropping the derive was a breaking change for downstream types that derive
Debug and hold a CommandChild.
* fix(shell): don't block the main thread in the kill command
CommandChild::kill now waits for the child to exit, and the sync kill
command ran it on the main thread while still holding the children lock.
Make the command async and release the lock before killing.

* fix(ci): Android e2e flakes, shell `Terminated` sent before output
- close "isn't responding" system dialogs before each spec and hide error dialogs on the CI emulator:
a launcher ANR dialog takes input focus from the app, and Android then denies clipboard reads
- retry switching to the webview context until it succeeds instead of running the spec in the
native context when the first switch fails with "No such context found"
- save the focused window, a screenshot and logcat when an Android test fails
- shell: wait for the pipe readers to finish before emitting `Terminated`; the readers took their
read lock on their own thread, so a child exiting quickly could have `close` emitted before
its output
