Merge branch 'openchamber:main' into github-usage-rework

CHANGELOG.md

@@ -10,6 +10,11 @@ All notable changes to this project will be documented in this file.
 - **Session tabs (opt-in):** the web/desktop header can show your open sessions as browser-style tabs — turn them on in Settings → General → Navigation → Session tabs. Every session you open joins the strip, clicking a tab switches the whole workspace (chat, project, panels), and closing one (its × button, middle-click, or Alt+W — rebindable in Shortcuts) never touches the session itself. Tabs reorder by drag, scroll behind the header buttons when there are many and carry the sidebar's running/unread dot. Each tab has the full session menu — on the "..." button or right-click — plus Close other tabs; renaming works right in the tab.
 - **Keyboard shortcuts learned sequences** (thanks @ChangeHow): shortcuts can now be two steps — press Cmd/Ctrl+S, then a letter: P opens the draft's project picker, G its branch picker, L the session list. A held sequence shows no menu but forgives you: Escape or three quiet seconds cancel it, and typing into a text field never triggers one armed elsewhere. Dropdown menus and pickers now also answer Ctrl+N/Ctrl+P for down/up, the session switcher opens focused on your current session, and every tooltip and menu label shows the binding you actually have set, not the default.
 - **Keyboard shortcuts redesigned.** Defaults now follow one model: single chords for everyday actions, a two-step Cmd/Ctrl+K leader for open/go actions (K then P/G/L — project picker, branch picker, session list; T timeline, N prompt navigator, I services, H shortcut help, C theme), held Cmd/Ctrl+digit for header session tabs and held Cmd/Ctrl+Option+digit for context panel surfaces. Cmd/Ctrl+B now toggles the sidebar; when it's already open, the session-list shortcut jumps into its search. Rare actions moved into the command palette instead of carrying obscure default bindings, and custom bindings recorded under the old layout are reset once. Shortcuts also stopped requiring an English keyboard layout — bindings follow the physical key on non-Latin layouts (and Option-modified digits on macOS), including when recording custom ones.
+- **Permission cards answer to the keyboard:** Alt+Enter allows once, Alt+Shift+Enter allows always, Alt+Backspace denies — the keys are printed on the buttons, and the newest pending card is the one that listens. The auto-accept toggle also got a shortcut (Cmd/Ctrl+K, A).
+- Sessions: Cmd/Ctrl+Alt+Left/Right steps back and forward through the sessions you opened in this window, browser-history style; with session tabs enabled it moves between neighbouring tabs instead. Cmd/Ctrl+K, R renames the current session right in the header.
+- Git: Cmd/Ctrl+Enter in the commit message box commits, like every git client.
+- Diff: Alt+Down/Up jumps review to the next or previous changed file, expanding it if collapsed.
+- Command palette: rarely used commands (pin session, copy session ID, multi-run launcher, archived sessions, notes, todos, status, theme, memory debug) are now found by typing but stay off the first screen, which keeps the initial list scroll-free.
 - Chat: comment on a reply — select text in a chat message (or in a rendered markdown preview in Files) and choose Comment to attach exactly that quote, with a source line range when it can be located, plus your note to the next message. The selection stays highlighted while you type, and the selection menu was restyled — Add to chat is now Add to input.
 - Diff: comment like a review — hovering a line shows a + button in the gutter; clicking it, clicking a line, or dragging across lines opens the comment editor for that line or range. The comment editor and saved-comment cards match the chat's comment style.
 - Composer: hovering or tapping a context chip above the input opens a stacked preview of everything attached, where a comment can be edited in place or an item removed before sending.

 - Chat: @ file mentions now rank files and directories together by how well they match, so the file you typed is at the top instead of below unrelated directories. Multi-word queries match in any order, and long paths keep the folder next to the file name visible.
 - Search: Ctrl/Cmd+P now matches the whole file path, not just the file name — searching a folder name finds the files inside it.
 - Search in dropdowns: searchable pickers (agents, models, providers, branches) now put the best matches first, match multi-word queries in any order, and ignore punctuation (so "gpt4o" finds "gpt-4o").
+- Permission cards answer to the keyboard: Alt+Enter allows once, Alt+Shift+Enter allows always, Alt+Backspace denies; the keys are printed on the buttons.
 - Keyboard: dropdown menus and pickers answer Ctrl+N/Ctrl+P for down/up, the session switcher opens focused on your current session, and shortcut labels in tooltips and menus show the binding you actually have set (thanks @ChangeHow).
 - Chat: OpenCode notices now share one style.
 - The timeline dialog now fits small windows instead of squeezing the message list to a couple of rows (thanks to @gaojunran).
