Consolidated re-apply of #96988 onto current main. Ported from
Merit-Systems/OpenInstinct (MIT) opaque-handle autofill design: the model
sees vault handles + login metadata, the password is resolved and filled
server-side over the supervised CDP socket, and filled values are scrubbed
from every browser tool result by an unconditional redaction registry.
Rebase adaptations to the Sep-2026 facade/sibling layout:
- toolsets: one _HERMES_CORE_TOOLS entry (the browser toolset derives from it)
- hermes_cli/main.py: vault parser registered via the subcommand owner table
- file_safety: vault/ joins the _READ_DENIED_DIRS credential-dir table
- redact: registry scrub runs before the redact_secrets early-return
- browser_vault_tool: _run_browser_command now lives in browser_tool_session
