example.3: Show updated library macro usage
The LIBRARY section has been deprecated by upstream.
Show the updated usage of the Lb macro in SYNOPSIS.
Fixes: 4c07abdbacf49 (mandoc: Vendor import of upstream at 2025-06-13)
examples/mdoc: Remove document description quotes
Quotes in roff do not work the way quotes in shell do,
remove them from the examples to hopefully lead less people astray.

bectl: log modifying functions to zpool history
Modeled directly after the method used by the zfs/zpool commands: flag
commands with a "please log me" flag, and when there, reconstruct the
command line. On success, call the library function to add it to the
log.

devel/janet-lsp: Compile as a portable "binscript"
Janet can compile to a portable "binscript" or a statically-linked
executable. The latter allows the LSP to work even without Janet
installed, but means that the LSP can be out-of-sync if the user
has a different version of Janet installed (the LSP will be unaware
of that new Janet and its capabilities).
To guard against such problems, switch to the binscript approach,
which compiles to an IR. Janet is a required runtime dep now, but
there's no risk of the LSP getting out-of-sync with the underlying
toolchain.

sdhci: Try to complete the last transaction if dumping
If the kernel panics while a thread is in the middle of an SDHCI
transaction, trying to dump to a dump target on the MMC would result in
a hang. Fix this by completing the transaction first.

vmm: Add ability to destroy VMs on close
This change adds the ability to tie a virtual machine's lifecycle to
a /dev/vmmctl file descriptor. A user can request `vmmctl` to destroy a
virtual machine on close using the `VMMCTL_CREATE_DESTROY_ON_CLOSE` flag
when creating the virtual machine. `vmmctl` tracks such virtual machines
in per-descriptor lists.

bhyve: Introduce monitor mode
This change introduces "monitor mode", a mechanism for automatically
releasing virtual machine resources when bhyve dies, bringing us
closer towards making non-root bhyve viable.
Under this regime bhyve will create a transient virtual machine using
`vmmctl`'s `VMMCTL_CREATE_DESTROY_ON_CLOSE` flag and automatically
reboot said virtual machine as long as it exits with "reboot" status.
This is done by splitting bhyve into two processes. The parent process
creates the virtual machine while the child process initializes and
runs the virtual machine. When the child exits the parent inspects
its exit status and either exits or forks again. `vmmctl` automatically
destroys the underlying virtual machine once the parent process dies.

bhyve: Eliminate exit status magic numbers
bhyve's exit status codes indicate how the VM was terminated.
Unfortunately, their meaning within the source code is somewhat
unclear since they are only used as magic numbers.
Fix this by defining exit status macros and using them to replace
the magic numbers in exit(3) function calls.

kern: Introduce RLIMIT_VMM
This change introduces a new per-UID limit for controlling the
number of vmm instances, in anticipation of unprivileged bhyve.
This allows ut to limit the amount of kernel memory allocated
by the vmm driver and prevent potential memory exhaustion attacks.

handbook/desktop: Refresh Plasma
I tried running plasma wayland on 15.0, it works great! CPU usage
is a tad high, but I'm impressed! Freshen the branding and language
in this chapter to highlight this. Remove a stale note about adjusting
message sizes to what is now the default. Tell the reader how to search
the kde-applications category. Add instructions to launch with wayland.
