Final v2 PR. All 11 planned write tools live. add_host/delete_host let
Claude mutate the saved-hosts list; both gated by a new allowAddHost
switch (default off) — symmetric with the allowOpenSsh gate from PR-3.5.
add_host's extraArgs are sanitised against CVE-2023-51385-class
local-RCE primitives: ProxyCommand, LocalCommand, KnownHostsCommand,
PermitLocalCommand=yes are refused server-side. Recognises both -o KEY=VAL
and -oKEY=VAL, case-insensitive on the key. The manual host manager UI
stays unrestricted (user has full agency over their own hosts).
Also fixes a pre-existing compile bug: mcp_policy.rs's policy_with test
helper was missing the ssh_safeguards field added in PR-3.5, silently
breaking the entire policy test module since then. Re-enabling those
tests is the prereq for the hard-deny rework that follows in the next
commit.
