Replaces #79, with the same changes and a clean commit history: every commit is one standalone change. Phase 3 of the scripting terminal UX improvements, stacked on #85.

I checked each problem on the previous phase's build in a dev client driven by clientdevbridge, then checked the feature with this branch.

Commit	Problem before	Result with this PR
Indent with tab in the script editor	Tab inserted nothing.	Tab inserts one indent, or indents every selected line; Shift+Tab removes one level.
Keep indentation on enter in the script editor	Enter after an indented line put the cursor in column 0.	The new line keeps the indentation, gets one more level after {, ( or [, and {} is split so the closing bracket gets its own line.
Highlight matching brackets in the script editor	Hard to see which bracket closes which block.	The bracket next to the cursor and its match are highlighted.
Add find and go to line to the script editor	No way to search; you had to scroll.	Ctrl+F opens a search bar below the editor to find text, and Ctrl+G opens it to go to a line number. It shows the current match and total (2/29), has previous/next buttons (also Shift+Enter / Enter), highlights all matches, and turns red when nothing matches or the line number is invalid. Escape closes the bar before it closes the screen. Checked in-game: wrap-around in both directions with the view following, the count updating while editing, the editor regaining its full height when closed, and the bar closing on resize.
Add toggle comment and move lines to the script editor	Commenting out or moving lines meant editing each line by hand.	Ctrl+/ toggles // on the current or selected lines; Alt+Up/Down moves them. Both are undoable.
Scroll the script editor while drag-selecting	Dragging below the editor stopped at the 12 visible lines.	The editor keeps scrolling while a selection is held above or below it, from about 5 lines per second right below the last line to about 50 further away, also when the mouse is held still. It stops on release (checked: no further scrolling 2 seconds after release), and works in both directions.
Make the indent size of the script editor configurable	The indent was a fixed 4 spaces, which is wide in the small editor and doesn't match every code style.	New client option terminalScriptingIndentSize (1–16), default 2, the common JavaScript style. Checked in-game: Tab and Enter-after-{ use 2 spaces; after changing the config file to 4, Tab added 4 without restarting the game.
Add toolbar buttons for editor actions	All of the above were only reachable through keyboard shortcuts, which players have no way to discover.	Small icon buttons next to the terminal title: undo, redo, find, go to line and toggle comment. Each tooltip shows the action and its shortcut. Undo/redo are dimmed and inactive when there is nothing to undo or redo. Longer translations of the title (for example pt_br) are cut off with … before the toolbar.
Make the script editor shortcuts rebindable	The shortcuts were hardcoded, so players couldn't change them, for example when they clash with another mod.	Undo, redo, find, go to line, toggle comment and move lines up/down are key mappings under "Integrated Scripting" in Controls, and the tooltips show the current key. Modifiers must match exactly, so Ctrl+Shift+Z doesn't trigger Ctrl+Z (5 unit tests). Ctrl+Shift+Z stays as a fixed extra redo key, since a key mapping can only have one modifier. Checked in-game: after rebinding Find in the Controls screen, the tooltip shows the new key, the new key opens find, and Ctrl+F no longer does.
Document the script editor shortcuts in the info book	The shortcuts were only discoverable through tooltips.	New "Editor Shortcuts" section after "Scripting Terminal", with a keybinding appendix per rebindable shortcut, and a paragraph for the fixed keys (Tab, Page Up/Down, word and line navigation including the macOS variants, search bar keys).

I left out duplicate-line, which was in the original plan: copy/paste already covers it.

Known issues

• The keybinding appendix only shows readable keys (CTRL + Z instead of key.keyboard.z) once Integrated Scripting depends on a CyclopsCore release with Show the bound key in key binding appendices CyclopsCore#255, which is merged.
• NeoForge's Controls screen marks Toggle comment (Ctrl+/) red, because it counts it as a conflict with vanilla's universal "Open Command" key (/). There is no actual clash at runtime, since our keys are only checked inside the terminal.

All text logic is in a new TextEditing class with unit tests, covering both indent sizes and the search helpers.

Testing

• Every commit compiles on its own, including tests and Spotless.
• ./gradlew build passes, including the new unit tests.
• ./gradlew runGameTestServer: all 23 tests pass.
