feat: Rebase on log buffer (#62)

Now it is possible to rebase interactively from the log buffer with visual feedback. You can rebase one or many visually selected changes.

Supported target modes are: `-o` / `-A` / `-B`.

Limitation:
	- As of now you cannot rebase a whole branch (-b) from the log view.

Bonus from this pr:
	- Now keymaps support different modes

+### Rebase changes from the log buffer
+
+Enter an interactive rebase mode directly from the log buffer to rebase one or more changes:
+
+- `r` - Enter rebase mode targeting the revision under cursor (in normal mode) or selected revisions (in visual mode)
+
+Once in rebase mode, the interface highlights your selection and the current rebase destination:
+
+- Selected changes are highlighted in your configured `selected_hl` color (default: dark magenta)
+- The cursor position (potential rebase destination) is highlighted in your configured `targeted_hl` color (default: green)
+- Move the cursor to preview different rebase destinations with live highlighting
+
+From rebase mode, choose how to rebase:
+
+- `<CR>` or `o` - Rebase onto (`-o`) the revision under cursor
+- `a` or `A` - Rebase after (`-A`) the revision under cursor
+- `b` or `B` - Rebase before (`-B`) the revision under cursor
+- `<Esc>` or `<C-c>` - Exit rebase mode without making changes
+
+**Visual mode selection:** Select multiple revisions in visual mode before pressing `r` to rebase them all at once. The plugin extracts each selected revision and rebases them together.
+
+**Single revision:** In normal mode, place your cursor on a single revision and press `r` to rebase just that change.
