Replace jline dependency with aesh-readline terminal-tty

[stalep]

With the picocli-to-aesh migration (#2453), jbang already depends on aesh's terminal-api module. The terminal-tty module from aesh-readline provides the same terminal capabilities that jline is currently used for.

Current jline usage

jline is used in 3 files for the interactive deps search TUI:

• Deps.java -- Terminal + TerminalBuilder for system terminal creation
• ArtifactSearchWidget.java -- Terminal, AttributedString, AttributedStyle, Capability for styled interactive search UI
• ComboBox.java -- BindingReader, KeyMap, Terminal, AttributedString, Capability for interactive combobox with key bindings

aesh-readline equivalents

jline	aesh-readline
Terminal / TerminalBuilder	Connection / PosixSysTerminal / WinSysTerminal (terminal-tty)
AttributedString / AttributedStyle	TerminalString / TerminalColor / TerminalTextStyle (terminal-api)
InfoCmp.Capability	Capability (terminal-api)
BindingReader / KeyMap	Key (terminal-api) + readline action mappings
Signal	Signal (terminal-api)
Attributes	Attributes (terminal-api)

Benefits

• Remove jline dependency (jline-console-ui, jline-terminal-jni, and their transitives)
• Reduce jar size
• Single terminal framework instead of two
• Better native image support (aesh-readline is designed for it)

Dependencies to add

implementation 'org.aesh:terminal-tty:3.8'  // or whatever version matches

Dependencies to remove

implementation "org.jline:jline-console-ui:$jlineVersion"
implementation "org.jline:jline-terminal-jni:$jlineVersion"

there is #2465 which should "fix" this.
