Subject: [PATCH 01/20] feat: add ShellDispatcher for shell-agnostic command
 execution

Introduces a central shell abstraction that replaces hardcoded
Command::new("cmd") / Command::new("sh") across the execution path.

- Shell detection at startup (pwsh -> powershell -> cmd -> sh)
- Correct quoting per shell (PowerShell uses -NoProfile -Command)
- Scope guards restore crossterm raw mode on all spawn paths (#1690)
- Direct program+args builder for sandbox ExecEnv integration

Files:
- crates/tui/src/shell_dispatcher.rs (new, 12 tests)
- crates/tui/src/main.rs (register module)
- crates/tui/src/eval.rs (exec_shell delegates to dispatcher)
- crates/tui/src/sandbox/mod.rs (CommandSpec::shell uses dispatcher)
- crates/tui/src/tools/shell.rs (raw mode guards on all spawn paths)

Closes #1690
Refs #1779

+//! Shell abstraction layer for DeepSeek TUI.
+//!
+//! Detects the user's shell at startup and provides a single entry point for
+//! all command execution. DeepSeek TUI never calls `Command::new("cmd")` (or
+//! `"sh"`, `"pwsh"`, ...) directly — it asks the [`ShellDispatcher`] to build
+//! a correctly configured [`std::process::Command`].
+//!
+//! ## Responsibilities
+//!
+//! 1. **Shell detection** — find the user's actual shell (PowerShell, pwsh,
+//!    bash via WSL / Git Bash, cmd.exe fallback on Windows, /bin/sh on Unix).
+//! 2. **Quoting correctness** — each shell's argument-passing convention is
+//!    respected so quoted strings survive the spawn boundary intact.
+//! 3. **Terminal state** — foreground shell execution saves and restores
+//!    crossterm raw-mode so the TUI input pipeline is not broken after a
+//!    child process exits (issue #1690).

Subject: [PATCH 02/20] feat(shell_dispatcher): harden PowerShell detection and
 add execution logging

- find_exe(): fall back to known install dirs when PATH lookup fails
  (C:\Program Files\PowerShell\7, System32\WindowsPowerShell\v1.0)
- Encoding prefix: use idiomatic [Console]::OutputEncoding for PowerShell
  instead of cmd.exe chcp 65001 >NUL
- Execution logging: write exec via <ShellKind> entries to
  SHELL_DISPATCHER_LOG when set
- System prompt: use ShellDispatcher detection instead of raw $SHELL
  so model knows it has PowerShell and generates native cmdlets
- display_command(): strip PowerShell encoding prefix for display
- Add tests for find_exe PATH + known-dir fallback

Refs #1779

- Fixed sandbox tests to accept sh/bash/zsh on non-Windows
- Added cfg_shell_program() helper that uses ShellDispatcher detection
- Marked find_exe_finds_cmd_on_path as #[cfg(windows)]
- Fixed shell::tests for issue_1691 to accept sh/bash/zsh
- Added #[cfg(windows)] to cmd-specific tests

Subject: [PATCH 12/20] fix: relax Windows test expectations for dynamic shell
 detection

ShellDispatcher may detect pwsh, powershell, or cmd on Windows.
Tests now verify the command is passed as the last arg instead of
hardcoding cmd.exe with chcp prefix.
