runa v0.8.0

Tabs added to runa. Better workflow and easier directory overview with up to 9 tabs.

Added:

• Tabs: Added the ability to add tabs and manage a multi-tab workflow.
• Tab Status Bar: Customizable status bar via tab.line_format.
• Widget Scrolling: Added widget scrolling to the delete, move action, and key-bind help widgets.
• Linux musl binaries: Added Linux binaries for musl.

Breaking Changes:

• Due to the new scroll feature for widgets, there has been a change in the default key bindings for runa.
• alternate_delete is now by default mapped to <m-d> or alt+d.
• clear_clipboard is now by default mapped to <f2>.

Changed:

• Clipboard: To enable cross-tab clipboard support, moved clipboard from ActionContext into the new central RunaRoot struct.
• Workers: Refactored worker ownership from AppState into the central RunaRoot struct.

Fixed

• Nav IO worker: Fixed issues caused by unbounded channel by switching to bounded(1).
• Border Shapes: Fixed an issue where the border shape would reset to "squared" on root and on previews.

Internal:

• RunaRoot: Added a central struct which holds Clipboard, AppContainer and Workers. Due to tabs being added, these data structures needed to be managed out of AppState.
• AppContainer: Added a internal container struct to manage and hold the new TabManager for tabs mode and a boxed AppState for single (no-tab) mode.
• CI: Improved CI workflow to check more build variants and include additional checks like clippy, fmt and audit.
• CI: Added cross to the CI and release workflows for Linux targets.
• Performance: Cached entry.path in core::fm::browse_dir to remove redundant calls whenever a directory has symlinks.
