fix: restore test safety plugins and correct core SDK path in conftest

Register the test_gating and network_guard plugins via
config.pluginmanager.import_plugin() in pytest_configure, which is the
supported mechanism for non-top-level conftest files under pytest 9.1.1+.
This restores test gating and network-guard enforcement that was dropped
when pytest_plugins was removed.

Also fix the core SDK sys.path insertion: praisonaiagents lives at
src/praisonai-agents, so traverse two parents ('..','..') to reach
<root>/src, not three.

+"""Trials engine: K isolated attempts per case, unified scoring, pass-rate + frontier.
+
+This is the missing runner behind :class:`~praisonaiagents.eval.package.EvalRunnerProtocol`.
+It answers "does my agent actually work?" with statistics instead of one sampled run:
+each :class:`EvalCase` is attempted ``k`` independent times, every completed attempt is
+scored through a single :class:`TrialScore` contract, and the report gives per-case
+pass rates plus the *frontier* band (cases with 0 < pass_rate < 1) where an agent is
+capable-but-inconsistent.
+
+Design (lightweight): stdlib only (asyncio, copy, json, time). Reuses the existing
+``Judge`` and the tool-assertion logic (``ReliabilityEvaluator._extract_tool_calls``).
+No new heavy dependencies, no new trace subsystem.
+
+Example:
+    from praisonaiagents.eval import EvalPackage, EvalCase, run_trials
+
+    package = EvalPackage(name="checkout", cases=[
+        EvalCase(name="refund", input="...", expected="...", verify=my_metric_fn),

+"""Event-loop liveness watchdog for long-lived gateway loops (Issue #3385).
+
+A gateway process can stay *alive* while its asyncio event loop is **wedged** —
+deadlocked, blocked on a synchronous call inside async context, or stuck on an
+``await`` that never returns. When that happens every asyncio-based recovery
+path (drain, scale-to-zero, reconnect supervision, the ``/live`` HTTP probe)
+is structurally unable to fire, because they all run *on* the frozen loop.
+Ordinary process supervisors only restart a process that has **exited**, so a
+wedged gateway becomes a silent zombie that holds its sockets and answers no
+messages until a human kills it.
+
+This module provides a small, dependency-free (pure stdlib) primitive that runs
+on a dedicated OS thread — so it keeps working precisely when the loop does
+not. It periodically probes the loop via ``loop.call_soon_threadsafe`` and
+measures scheduling lag; after *N* consecutive missed probes it declares the
+loop wedged, optionally dumps all-thread stacks via :mod:`faulthandler`, and
+forces a clean hand-back to the supervisor via ``os._exit`` (bypassing
+``Py_FinalizeEx``, which would itself hang joining the stuck threads).
+
+Design principles:
+
+* **Opt-in.** Nothing arms the watchdog unless an embedder calls :meth:`arm`.
+* **Fail-open.** Any error inside the watchdog must never wedge or kill a
+  healthy gateway. Once armed, it only ever *reacts* to a confirmed stall.
+* **No heavy deps.** Only :mod:`threading`, :mod:`faulthandler`, :mod:`os`,
+  :mod:`sys`, and :mod:`time` from the stdlib.
+
+The primitive lives in core so every embedder — not just the CLI gateway — can
+opt into the same liveness/self-recovery contract around any long-lived loop.
+Deployment wiring (systemd ``Type=notify`` / ``WatchdogSec``, CLI flags) is a
+wrapper concern and intentionally not part of this module.

 Add a language/domain by registering a `Recipe`, or a new QC rule by registering a
 `RowCheck` (see `praisonai_train/data/`), and they show up automatically.
+
+## Verify → export → train → re-verify (learn from real agent runs)
+
+Beyond synthetic generation, you can fine-tune on the agent's *own* verified
+behaviour. Given a trials report (K scored attempts per case with captured
+trajectories), `from-trials` keeps the passing attempts and writes a
+trainer-ready dataset — closing the loop from verification to data generation.
+
+```bash
+# 1) export the passing attempts as a ShareGPT dataset (+ provenance sidecar)
+praisonai-train data from-trials trials.json -o data/train.jsonl
+
+# 2) fine-tune with the existing trainer, unchanged
+praisonai-train llm --dataset data/train.jsonl
+
+# 3) re-run the trials on the fine-tuned model and compare pass-rate to measure gain
+```
+
+```python
+from praisonai_train.data import export_trials
+
+summary = export_trials(
+    report, "data/train.jsonl",
+    only_passed=True,     # rejection sampling on the verifier (default)
+    frontier_only=True,   # skip saturated / zero-pass cases (default)
+)
+print(summary)  # written / skipped_failed / skipped_tool_runs / skipped_no_text / ...
+```
+
+Selection defaults: unscored attempts are never candidates; `only_passed` keeps
+verifier-passed attempts; `frontier_only` restricts to cases with
+`0 < pass_rate < 1` (saturated cases add near-duplicates of mastered behaviour,
+zero-pass cases have nothing to export); tool-using runs are excluded by default
+(`--all`, `--include-saturated` relax these). A `{out}.jsonl.meta.json` sidecar
+maps every line to its case id, attempt index and score, and emission order is
+deterministic → reproducible files. Add `--qc` to run rows through the same QC
+filter as `validate`, or `--format alpaca` for instruction/input/output.
+
+> **Honest selection:** `only_passed` is *rejection sampling* — it amplifies
+> behaviour the agent already produces and inherits any bias in the scorer/judge
+> that decided a run "passed". It cannot teach behaviour the agent never
+> exhibited; treat it as reinforcing verified wins, not as an oracle.
