Expose three new Lua plugin APIs for the git history plugin: - ttt.open_diff(title, old_lines, new_lines, file_path) — opens a native styled diff tab using the existing DiffViewWidget - ttt.open_readonly(title, lines, file_path) — opens a buffer tab with content provided directly, in readonly mode - ttt.open_file(path, line, readonly) — extended with optional third argument to open files in readonly mode Readonly tabs block all mutations (typing, enter, backspace, delete, tab/backtab) and refuse to save. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
These APIs open read-only tabs, same as open_file — no permission needed. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
ttt.open_diff(title, old_lines, new_lines, file_path)Lua API — opens a native styled diff tab using the existingDiffViewWidget, enabling plugins to render side-by-side diffs from arbitrary content (e.g. git commit diffs)ttt.open_readonly(title, lines, file_path)Lua API — opens a readonly buffer tab with content provided directly, with syntax highlighting based onfile_pathextension (e.g. viewing a file at a specific git commit)ttt.open_file(path, line, readonly)with optional third boolean argument for readonly modeReadOnlyflag toeditorTabandEditorPaneWidgetthat blocks all mutations (typing, enter, backspace, delete, tab/backtab) and refuses to saveopen_diffandopen_readonlyrequirepanel.editorpermissionThese are the core primitives needed for a git-history plugin to show per-file commit history with native diff rendering and historical file viewing.
