Summary

Append now, --yes, or -y to any destructive slash command (/reset, /new, /clear, /undo) to bypass the confirmation modal — gives users on platforms where the modal doesn't dispatch keys (native Windows PowerShell, issue #30768) an immediate self-service unblock without flipping approvals.destructive_slash_confirm in config.

Changes

• cli.py: new classmethod HermesCLI._split_destructive_skip(text) parses out skip tokens (case-insensitive exact match — now, --yes, -y). _confirm_destructive_slash gains an optional cmd_original= argument and returns "once" immediately when a skip token is present, before the gate check and before any modal rendering. The three call sites (/clear, /new, /undo — /reset resolves to new via alias) pass cmd_original through. /new additionally strips skip tokens from the title so /new --yes My Session yields title="My Session" instead of title="--yes My Session".
• tests/cli/test_destructive_slash_confirm.py: +7 unit tests covering the helper (recognized tokens, command-word stripping, case-insensitive exact match, defensive empty/None input) and the modal bypass (now and --yes both skip; no-skip-token still consults the modal).
• tests/cli/test_destructive_slash_inline_skip_e2e.py (new): 3 integration tests driving HermesCLI.process_command end-to-end — proves new_session runs, the modal is never invoked, the skip token doesn't leak into the title, and the no-skip path still reaches the modal as a sanity check that we haven't accidentally short-circuited normal flow.
• website/docs/reference/slash-commands.md: documents the new flags in both the destructive-commands table and the dedicated approval section, with a link to Bug: /reset and /new slash commands freeze on Windows — routes to interactive CLI menu #30768.

Validation

All 31 tests across the destructive-slash test surface pass on Windows:

tests/cli/test_destructive_slash_confirm.py ............... 16 passed
tests/cli/test_destructive_slash_inline_skip_e2e.py ........ 3 passed
tests/hermes_cli/test_destructive_slash_confirm_gate.py .... 5 passed
tests/cli/test_cli_new_session.py .......................... 7 passed
============================= 31 passed in 1.19s ==============================

The Linux modal path is byte-identical to before for callers that don't pass a skip token (the new cmd_original arg defaults to None, and when None or empty the function falls through to the existing gate/modal logic). The test_confirm_destructive_slash_no_skip_token_still_prompts and test_new_without_skip_token_still_consults_modal tests pin that invariant.

Notes

• This is a deliberately surgical fix that ships independently of the underlying Windows modal investigation — root-causing the win32 prompt_toolkit key-dispatch issue is out of scope for this PR.
• I was unable to do a live PowerShell repro of the original freeze from inside this agent's terminal (driving an interactive TUI from a non-TTY parent is precisely the situation that has caused freezes before — the bug we're trying to escape from). The unit + e2e tests cover the codepath that runs when a skip token is present; that codepath returns "once" without ever touching _prompt_text_input_modal, so it cannot hit the broken win32 dispatch regardless of platform.
• Token set deliberately small (now, --yes, -y) and uses exact-match (not substring) so titles like Now-Title or do-this-now are unaffected.
