mgabor3141 4d5cbf22c0 client: recognize kitty keyboard protocol encoding of detach key 
Modern terminals (kitty, wezterm, foot, ghostty) and shell/editor
applications (fish, neovim, helix) increasingly use the kitty keyboard
protocol, which encodes key presses as CSI u sequences instead of raw
control bytes:

  Ctrl-\  legacy: 0x1C  ->  kitty protocol: ESC [ 92 ; <mod> u

The modifier field encodes all active modifiers including lock keys:
  modifier = 1 + (shift:1|alt:2|ctrl:4|super:8|...|capslock:64|numlock:128)

For example, Ctrl-\ with numlock on produces ESC[92;133u, not 0x1C.
Since abduco only checked for the single-byte value, the detach key was
silently ignored whenever the keyboard protocol was active — which is
the default state at a fish shell prompt or inside neovim/helix.

This adds a CSI u parser alongside the existing single-byte check in the
client read loop. The parser:
- Extracts the Unicode codepoint and verifies it matches the detach key
- Extracts the modifier bitmask and checks that ctrl (bit 2) is set
- Ignores other modifier bits (numlock, capslock, shift, etc.)
- Handles the optional event type suffix (:1 press, :2 repeat, :3 release)
- Works with any detach key configured via -e

Closes #66

Marc André Tanner 7d0e9d91b6 Create leading directories when installing 
Note: install(1) is not really specified and the -D option does not
seem to be portable. For example the FreeBSD manual page documents a
different behavior.

We therefore use a somewhat ugly two step process with an installdirs
target.

Marc André Tanner 8f80aa8044 Do not implicilty enable passthrough mode if no session name is given 
Even when no session name was provided the passthrough flag was still
implicitly enabled in case stdin was not a terminal. This behavior
prevented the session list from being printed i.e.

  abduco < /dev/null

would not work as expected. Only enable implicit passthrough if stdin
is not a terminal *and* a session name is given.

Marc André Tanner fd34b98db7 Add explicit option for command pass through 
This allows commands to be send interactively (i.e. when stdin refers
to a terminal). Also imply attach action if none is given, hence:

    $ abduco -p session
    cowsay hi
    ^D

can also be used to send input to a session.

Marc André Tanner c901f2bbb8 If stdin is not a terminal pass-through its data to the session 
This allows to send commands to a running session:

    echo cowsay hi | abduco -a session

See #8 for initial discussion of the feature.

Marc André Tanner 8964601fe1 Use fixed size integer types in protocol messages 
This should make it possible to connect with a 32bit client to a 64bit
server. This might also make it possible to forward the abduco socket
over SSH as described in #25. Different endianness are not supported at
this time.

This is a breaking protocol change. Make sure to use the same version
as client and server (anything else is unsupported anyway!).
