Bug Fixes

• check that_detached launchers for immediate failures
  that_detached() returned as soon as a launcher spawned, so a launcher that
  failed right after starting was reported as success and no fallback ran.

  Observe each launcher for 250 ms by delegating to
  that_detached_with_timeout(). A launcher that exits unsuccessfully within
  that window falls through to the next candidate; one still running is treated
  as handed off. The macOS and shellexecute-on-windows paths are unchanged.

  Extend the fixture tests to call that_detached() directly.

• restore launcher fallback and support Plasma 6

  When xdg-open starts but exits unsuccessfully, that() and the CLI
  previously stopped before trying another installed opener. On Plasma 6,
  the fallback list also omitted the versioned KDE launchers.

Launcher behavior

• Retry reported failures from UNIX desktop launchers and retain the first
  unsuccessful exit when later candidates are missing.
• Add kde-open6 and kde-open5 before the existing kde-open fallback.
• Keep launcher ordering, argument boundaries, and exit-status policy
  together so compatibility decisions are explicit.
• Preserve Windows' stop-on-failure policy and the existing protections
  for option-shaped and non-UTF-8 paths.

Bounded detached checks

Add that_detached_with_timeout(path, timeout) to opt into checking the
actual launcher status for a configurable interval per candidate. Retry
confirmed UNIX launcher failures; consider successful exits or launchers
still running at the deadline handed off. A zero timeout polls once.

On UNIX, use setsid() while retaining the launcher as a child. Reserve a
background waiter before spawning and transfer ownership after a timeout
so the launcher can outlive its caller and is eventually reaped. Stop
fallback if observing an already-started launcher fails, avoiding a second
launch based only on a wait error. Existing detached calls retain their
timing behavior. The new API uses command-based launchers on Windows,
including when shellexecute-on-windows is enabled.

Historical constraints

55dc10d relaxed exit checks for argumentless availability probes, where
usage errors are expected. It did not establish that failed real opening
operations should stop fallback. 245c95e introduced that behavior;
the earlier implementation retried unsuccessful operations.

Keep stderr redirected to null: 30a144a and 0bdc6d6 document previous
pipe deadlocks and hangs. Do not interpret the successful double-fork
intermediate child's exit as launcher success (a78c0ca, 43e601d).

Document these constraints and upstream launcher behavior in
docs/launchers.md. Exclude kioclient exec, which enables execution
beyond kde-open's behavior, and arbitrary file-manager or AppImage
environment fallbacks that could override configured handlers.

Validation and limits

• Default and all-feature Linux tests pass, covering fallback, error
  selection, Plasma 6 reachability, timeouts, child reaping, survival after
  caller exit, large stderr output, argument protection, and CLI behavior.
• Formatting, git diff --check, and all-target, all-feature Linux clippy
  pass. Windows and macOS compile checks and clippy also pass.
• Actual desktop and AppImage behavior still needs testing. A handler
  that opens a target before reporting failure can cause a duplicate open
  when retried. Failures after the timeout cannot trigger fallback.
