Clear stale yolo approval state on no-launch reruns (#6868)
* Clear stale yolo approval state on no-launch reruns

The no-launch session config dir is deliberately reused across runs, but
the config writers only ever added the --yolo auto-approval settings and
never removed them. After one --yolo --no-launch run, every later run
without --yolo kept OpenClaw's tools.exec security=full/ask=off policy
plus exec-approvals.json, and OpenCode's permission allow block, so tool
execution stayed silently pre-approved.

Non-yolo runs now reset that state: OpenClaw drops the exec policy keys
and the yolo defaults in exec-approvals.json (approvals OpenClaw itself
recorded are kept; the file is removed when only the yolo payload is
left), and OpenCode drops the permission block. Launch mode is untouched
since it already uses an ephemeral temp dir.

* Strip only yolo-written values on non-yolo cleanup

Match each field against the exact value the yolo path writes before
removing it, so a stricter exec policy, approvals defaults set by the
user or the OpenClaw UI, and deny/ask OpenCode permission entries all
survive a plain no-launch rerun. An unparseable exec-approvals.json is
left in place, matching how an unparseable config is handled.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Write a prompting policy on non-yolo instead of deleting to a permissive default

OpenClaw and OpenCode both treat an omitted policy as permissive: OpenClaw's
effective exec policy for an unset tools.exec is security=full/ask=off on the
gateway host, and OpenCode defaults an unset permission to allow. So clearing
the yolo values on a non-yolo run did not restore prompting, it fell back to
those permissive defaults and left tool execution auto-approved.

A non-yolo run now writes an explicit prompting policy: OpenClaw gets
security=allowlist/ask=on-miss (verified to prompt even with the approvals file
removed, since the stricter of config and approvals wins), and OpenCode gets
edit/bash/webfetch=ask. Only a permissive/yolo value is tightened; a stricter
deny (or an ask the user set) is preserved, and the yolo approvals defaults are
still stripped. The file-edit CI path opts opencode/openclaw into --yolo, since
those agents now prompt by default and the headless test needs auto-approval.

* Respect existing exec mode, sandbox/node host, and global permission rules on non-yolo reset

The non-yolo reset for openclaw/opencode assumed an omitted policy was the
permissive yolo default and rewrote it, which corrupted or weakened stricter
setups it should have preserved:

- OpenClaw tools.exec.mode is the normalized policy knob and cannot be combined
  with explicit security/ask (OpenClaw rejects the whole config), so writing
  security+ask alongside a mode:deny/ask policy both broke the config and
  relaxed it. Leave a mode-based policy untouched.
- host=sandbox defaults to security=deny and host=node routes to a paired node;
  neither is written by --yolo (which only writes host=gateway). Treating the
  missing security as full and popping host broadened those into gateway/auto
  exec. Only rewrite a gateway-routed permissive policy, and never pop a
  non-gateway host.
- OpenCode permission can be a string ("deny") or a {"*": ...} catch-all.
  The old code dropped a string form and overrode a catch-all by writing
  per-tool ask, weakening a stricter user rule. Now a string is left in place,
  a catch-all governs absent tools, and only an effective allow is tightened.
- The non-yolo ask policy only lived in OPENCODE_CONFIG, which loads below
  project opencode.json, so a project config allowing edit/bash/webfetch still
  auto-approved. Carry the ask policy in OPENCODE_CONFIG_CONTENT (above project
  config) too, symmetric to how yolo carries its allow.

Also harden the openclaw path against a malformed non-dict tools value.

Adds tests for mode/sandbox/node hosts, string and catch-all permissions, and
the inline ask policy over a project config.

* Scope non-yolo resets to the exact yolo fingerprint and preserve granular denies

OpenClaw: reset only the exact host=gateway/security=full/ask=off policy --yolo
writes, so an omitted or host=auto/sandbox/node policy (which can resolve to a
sandbox security=deny default) is no longer broadened to allowlist/on-miss, and a
deliberate tools.exec.mode is left alone (OpenClaw never migrates our security/ask
write into a mode).

OpenCode: carry a granular object or a deny inline verbatim so a per-tool user rule
is not collapsed to a blanket ask, but floor any object that grants allow anywhere to
the string ask (which fully replaces a project object) so no inline allow pattern can
leak through into a silent auto-approve on a non-yolo session.

* Stop overriding project config on non-yolo; require full approvals fingerprint

The non-yolo OpenCode reset carried a session permission in
OPENCODE_CONFIG_CONTENT, which outranks the project opencode.json we
cannot read. That inline override could not correctly reflect the project:
it weakened a project deny to a prompt, mishandled global string rules,
leaked through a granular object's permissive default when no catch-all
was present, collapsed an object with an allow (losing its deny), and
missed per-agent permissions. All of these stem from forcing a value over
an unknown project config.

A non-yolo run now only undoes what --yolo wrote: it flips our own
explicit per-tool allow back to ask in our config file and carries no
permission inline, so the project's own permissions are honored as
written. Clearing our persisted yolo state is the actual fix; --yolo still
carries its allow inline so it works over a project config.

OpenClaw approvals cleanup now strips the yolo defaults only when the full
fingerprint (security=full, ask=off, askFallback=full) is present, so a
mixed user policy that merely shares askFallback=full (whose omitted
default is deny) is kept intact.
