core/tools: add ask_into_pty for human-local PTY input

Browse Source 
Prompt the human (optional no-echo secret) and write only to the PTY.
Tool results never include the answer so secrets stay off external APIs.
Empty/Ctrl-C cancel without writing; submit defaults to trailing newline.

- **`workspace`**: path resolve under primary root **or** temporary allowlist roots; path substring denylist; command basename denylist; clearer deny messages.
- **`file`**: `read_file` (`with_lineno`), `write_file`, `listdir`, `tree` (VCS + default noise dirs + optional `skip_dirs` / denylist walk), `glob_paths`, `grep_files` (regex, skip VCS/binary), `edit_replace` (`max_replaces`, reports remaining matches), `edit_lineno` (1-based range), `copy_path` / `move_path` / `delete_path`, `new_temporary_workspace` (system temp allowlist; cleanup on chat exit; no session rebind).
- **`process`**: `run_command` (argv, no shell, timeout, optional stdin/env); `run_command_batch` (serial steps, `pipe_out` on provider, `mix_stderr`, `stop_on_error`); PTY `open_pty` / `read_pty` / `write_pty` (literal) / `write_pty_keys` (escapes) / `close_pty` (POSIX: `pty`+`fork`; Windows: ConPTY via `pywinpty` env marker dep).
- PTY: backend in `pty_backend.py`; structured status (`alive`/`exit_code`/`data`); `read_pty(..., until=)` (**CSI sanitized** so host TTY is never reset); keys via `write_pty_keys` only (`\xHH`, `ctrl+x`, `key=esc`); session limit/idle TTL/output budget; close terminate→kill.
- **`process`**: `run_command` (argv, no shell, timeout, optional stdin/env); `run_command_batch` (serial steps, `pipe_out` on provider, `mix_stderr`, `stop_on_error`); PTY `open_pty` / `read_pty` / `write_pty` (literal) / `write_pty_keys` (escapes) / `ask_into_pty` (human→PTY only; `secret` no-echo; answer never in tool result) / `close_pty` (POSIX: `pty`+`fork`; Windows: ConPTY via `pywinpty` env marker dep).
- PTY: backend in `pty_backend.py`; structured status (`alive`/`exit_code`/`data`); `read_pty(..., until=)` (**CSI sanitized** so host TTY is never reset); keys via `write_pty_keys` only (`\xHH`, `ctrl+x`, `key=esc`); secrets via `ask_into_pty` (not `write_pty` data); session limit/idle TTL/output budget; close terminate→kill.
- CLI limit hooks: interactive confirm to raise tool-loop rounds, PTY session cap, or PTY output budget.
- Destructive confirms: `classify_danger` + `ToolRegistry(on_confirm=…)`; CLI default deny; config `confirm_destructive` / `path_denylist`. Soft confirm also for shells/REPLs and `python|bash -c` one-liners (argv + code preview); deny may include a user comment for the model. Session YOLO: `/yolo on|off|once` and `--yes` (skip soft confirms; hard denylists unchanged; `once` expires after the next user turn).
- **`vcs`**: read-only VCS tools (`vcs_kind` / `vcs_status` / `vcs_diff` / `vcs_log` / `vcs_branch`) via `VcsBackend` protocol; **git** implemented; detectors are pluggable for other systems.
