feat(safety): workspace-file reads, approval UX, and integration hardening

Engine + integration:
- Reviewer inspection now surfaces the real frozen source of an already-frozen
  workspace script/dependency instead of an empty string, so workspace-resident
  scripts resolve without a needless human defer.
- Guard effectful static tools via an explicit, documented set plus the SDK's
  per-tool needs_approval signal; give the exec/stdin wrappers the same
  idempotency guard as their sibling wrappers.
- Centralize DEFAULT_SAFETY_MODE and share one resume safety-mode rule between the
  CLI and runner so the two cannot drift; type InspectionContext.runner, reuse
  RUNTIME_STATE_DIR_NAME, and drop a dead workdir parameter and a write-only field.

TUI approval experience:
- Approve All drops the run into dangerous mode: it approves the pending call and
  turns review off for the rest of the run, with a standing "review off" status flag.
- The status row shows the owning agent as paused while it waits on a decision.
- Redesigned prompt: a risk + tool header, a collapsible command/reason preview
  that expands (e) and scrolls, and no internal digest, agent, or request ids.

Full Python (1138) and Go suites, ruff, and mypy strix/ pass.

The safety model may decide immediately or make exactly one `run_inspection`

separate networkless, read-only container over the frozen evidence. For an
incomplete packet in the interactive TUI, the reviewer must use that call to
pinpoint the missing evidence and determine what the available artifacts still
establish. If the tool is used, the model's next response must be the final
decision.
The review is bounded to at most two model turns and one optional inspection
call. Timeouts, malformed decisions, a second tool call, incomplete evidence,
and reviewer failures fail closed.
That single call can request explicit files or trailing-slash directories under
`/workspace`. Strix uses fixed read/list primitives to freeze bounded regular
files, directory listings, bytes, and digests into the evidence bundle, skipping
symlinks and special files, and returns bounded previews to the reviewer. The same call may
run a networkless analysis script over the augmented read-only bundle. The
reviewer never executes model-authored commands in the live workspace, and the
collected files become part of final fingerprint revalidation.
In the interactive TUI, the reviewer can defer when complete evidence still
leaves genuine ambiguity about whether an exact action is dangerous. Strix then
pauses that tool call and asks the user to approve or deny it. Denial is selected
by default, Escape denies, and the request waits until it is answered, the agent
is stopped, or Strix exits. Approval applies only to the frozen call shown in
the prompt; actions too large to display exactly must be split into smaller
tool calls. Deterministic blocks, incomplete evidence, review errors, and
Evidence acquisition gaps and reviewable uncertainty are distinct. Missing,
unreadable, truncated, or unfrozen bytes are hard gaps and cannot support an
automatic allow. When all relevant code and inputs are frozen but values such as
a request destination or subprocess argument require correlation, the packet is
`reviewable`; one successful inspection may resolve and allow it without asking
the user. Only unresolved ambiguity is deferred.
The review is bounded to at most two model turns and one inspection call.
Timeouts, malformed decisions, a second tool call, and reviewer failures fail
closed.
In the interactive TUI, the reviewer can defer when the evidence still leaves
genuine ambiguity about whether an exact action is dangerous. This includes an
incomplete packet after the one inspection call has identified its unresolved
gaps. Strix then pauses that tool call and asks the user to approve or deny it.
The prompt shows the risk, the tool, and a preview of the command and reason;
press `e` to expand the full command and reason and scroll them with the arrow
keys. Denial is selected by default, Escape denies, and the request waits until
it is answered, the agent is stopped, or Strix exits. Approval applies only to
the frozen call shown in the prompt; actions too large to display exactly must
be split into smaller tool calls. Deterministic blocks, review errors, and
actions confidently judged dangerous cannot be overridden.
Non-interactive runs have no human approval channel. Ambiguity and
low-confidence decisions continue to block, preserving fail-closed autonomous
behavior.
The prompt also offers **Approve All**, which approves the pending call and then
turns review off for the rest of the run — every later action runs unreviewed,
exactly as if the scan had started with `--dangerously-disable-safety`. A
standing "review off" flag on the status row marks that the run is no longer
being checked. Use it only when external containment already bounds the blast
radius.
Approval prompts are scoped to their owning agent. The agent list marks the
waiting owners with yellow indicators; select each agent to see and resolve its
own prompt. Multiple agents can wait for independent approvals at the same time,
and resolving one does not hide or block the others. You can continue navigating
the agent list with the keyboard or mouse while approvals are pending, and
returning to an owner reopens its prompt with Deny selected.
Non-interactive runs have no human approval channel. Ambiguity, incomplete
evidence, and low-confidence decisions continue to block, preserving

When a command reads a workspace data file — through input redirection
(`while read … done < hosts.txt`) or a target-list flag (`ffuf -w words.txt`,
`httpx -l hosts.txt`) — that file's contents are attached to the packet so the
reviewer can assess the exact entries, queried hosts, or fuzz inputs instead of

truncated inputs make the packet incomplete and follow the headless-block or

Evidence collection is serialized briefly to produce a consistent snapshot;
model review and human waiting remain concurrent. If another agent changes the
workspace during review, Strix refreshes and compares the actual evidence
fingerprint. Unchanged evidence executes without interruption. Changed scripts,
dependencies, inputs, or missing-file observations are automatically reviewed
again, with a new approval only when the refreshed review still needs one.
