Contour: baixar versions anteriors

A lot has happened since our last release, and that was already too long ago. So now, it is finally time to tag a release, with an already way too long list of great improvements as well as fixes.
Contour 0.7.0 makes the window a workspace: native GUI tabs in the title bar, split panes, saved layouts, and an optional terminal-styled UI that draws the application's own chrome on the character grid. It adds an experimental daemon mode for sessions that outlive the window showing them, accessibility support across the terminal and its chrome, the kitty graphics, text-sizing and clipboard protocols, ReGIS vector graphics, and a large round of VT conformance work.
Tabs, splits and layouts
- Adds first-class GUI tabs presented in a custom window title bar, replacing the status-line tab list (the {Tabs} status-line directive remains supported for existing configs)
- Adds split panes — split the active pane vertically (Ctrl+Shift+E) or horizontally (Ctrl+Shift+O), close a pane (Ctrl+Shift+X), and move pane focus with Alt+Shift+Arrow
- Adds pane management actions: swap the active pane with a neighbor (Ctrl+Alt+Arrow), resize it (Ctrl+Shift+Alt+Arrow), flip a split's orientation (Ctrl+Shift+Backslash), and move a pane to a new position in the split tree (unbound by default)
- Adds pane zoom (TogglePaneZoom, Ctrl+Shift+Z): gives the active pane the whole tab area, hiding its siblings, and toggles back to the tiled layout. Moving pane focus while zoomed keeps the zoom and shows the newly focused pane; splitting, closing or rearranging panes returns to the tiled view. A zoomed tab is titled after the pane on screen and wears a Z badge
- Adds dragging tabs: reorder a tab within its strip, drag it into another window, or tear it out into a new window, with a live drop-position indicator showing where it will land; the running terminal survives the move (within the same process)
- Adds renaming a tab by double-clicking it, and a color-swatch picker in its context menu. The picker is keyboard-driven — the cursor keys and the vim motions h/j/k/l walk the swatches, Enter or Space picks the highlighted one, Escape dismisses — and opens on the color the tab already wears
- Adds the actions SetTabColor and ResetTabColor, so coloring a tab is no longer mouse-only: both appear in the command palette, and either can be bound in input_mapping. SetTabColor opens the tab's color picker, or applies a color outright when given one (for example { mods: [Shift,Control], key: 'R', action: SetTabColor, color: '#ff0000' })
- Adds configurable layouts: named sets of tabs with per-tab command, working directory, name, color, profile, and split panes; open at startup via default_layout, via --layout NAME, or the LaunchLayout action. SaveLayout writes the current window's tabs back into layouts.yml, prompting for a name when none was given — and is reachable from the command palette, so saving a layout needs no keybinding
- Adds the dim_unfocused profile option: dims a pane while it is not the focused one (an inactive pane of a split, or any pane of an unfocused window) by blending it toward its background color; 0.0 (default) disables dimming
- Adds the top-level options tab_bar_position (Top/Bottom) and tab_bar_visibility (Always/Never/Multiple), to place the GUI tab bar at the top or bottom of the window and to hide it entirely or show it only when more than one tab is open
- BREAKING: tab_bar_position and tab_bar_visibility belong to the top level of contour.yml, not to a profile — a window shows one tab bar whichever profiles its tabs run. If you tried them in a 0.7.0 prerelease, move these two keys out of your profiles: block; a profile-scoped copy is no longer read
- Adds Ctrl+Tab / Ctrl+Shift+Tab and Ctrl+PageDown / Ctrl+PageUp as tab-switching shortcuts. They reach existing configurations too, and binding them yourself still wins. Note that Ctrl+Tab is now taken from applications that request it through the Kitty keyboard protocol
- Adds switching tabs wi

Dear package maintainerss
We've bumped the libunicode dependency to version 0.9.0: https://github.com/contour-terminal/libunicode/releases/tag/v0.9.0
Dear macOS users
I find it incredibly hard to package for macOS these days. The project perfectly compiles and runs self built on macOS, but packages build automatically won't. I am still looking into solving this issue. However, if you are one of those guys wanting to help us getting Contour back on track for macOS, we very much welcome contributions, specifically for macOS and the project in general.
Now let's continue with the regular release notes list:

A note on macOS:
Dear macOS users, we sadly were not able to package a self-contained installer for Contour such that you could simply download and install it without any problems. Contour perfectly builds and runs on macOS (any architecture) when built. We want to revive providing .dmg downloads as soon as possible.
Help wanted: If you know how to properly package a self contained C++ application on macOS, please contact us. :-)
