Simplify markdown rename to inline field without breadcrumb or buttons

Replaces breadcrumb-morph rename with confirm/cancel buttons with a
simple inline field accepting full filenames. Commits on Enter, blur, or
Escape to cancel, matching tab bar and file explorer behavior. Adds
renameCancelledRef to prevent blur-commit after Escape. Removes unused
i18n strings for buttons and simplifies state by dropping extension
pinning and breadcrumb display.

 - **Keyboard shortcuts**: Never hardcode `e.metaKey`. Use a platform check (`navigator.userAgent.includes('Mac')`) to pick `metaKey` on Mac and `ctrlKey` on Linux/Windows. Electron menu accelerators should use `CmdOrCtrl`.
 - **Shortcut labels in UI**: Display `⌘` / `⇧` on Mac and `Ctrl+` / `Shift+` on other platforms.
 - **File paths**: Use `path.join` or Electron/Node path utilities — never assume `/` or `\`.
-- **Windows terminal shells**: `--shell` picks the shell a terminal *is*; `--command` is typed into whatever shell the host spawned, so a shell choice routed through `command` silently becomes a child process.

+- **Windows terminal shells**: `--shell` picks the shell a terminal _is_; `--command` is typed into whatever shell the host spawned, so a shell choice routed through `command` silently becomes a child process. See [`docs/reference/windows-terminal-shell-selection.md`](./docs/reference/windows-terminal-shell-selection.md).
 - **Windows setup scripts**: the setup/issue-command runner is a `.cmd` batch file unless the script starts with a `#!` line — never derive that from the user's terminal-shell preference, and never launch a `.cmd` runner with a bare `cmd.exe /c` from a Git Bash pane (MSYS rewrites the `/c`). See [`docs/reference/windows-setup-shell.md`](./docs/reference/windows-setup-shell.md).
 - **Windows child processes**: start them through `runProcess`/`spawnProcess` in `src/shared/child-process/` — never `child_process` directly. It pins `windowsHide`, refuses `shell: true`, and encodes `.cmd`/`.bat` arguments so neither `CommandLineToArgvW` nor `cmd.exe` mangles them. A ratchet test fails on any new direct import. Recognised npm/pnpm `.cmd` shims are resolved to their real target so the spawn skips `cmd.exe` entirely; see [`docs/reference/windows-cmd-shim-resolution.md`](./docs/reference/windows-cmd-shim-resolution.md) before adding a shim shape or debugging one.
 - **Windows process enumeration**: read the table through `src/main/windows/windows-process-table.ts`, never by forking `powershell.exe`. See [`docs/reference/windows-process-enumeration.md`](./docs/reference/windows-process-enumeration.md).
