revert: restore intentional defects in ai_code_editor_fixture

The AI code-editor smoke-test fixture is intentionally broken so live
scenarios (implement celsius_to_fahrenheit / fahrenheit_to_celsius / mode,
fix mean/median empty-list handling) exercise the AI editor's repair
capability. Pre-implementing these functions caused acceptance tests to
pass WITHOUT the editor doing any work, defeating the fixture's purpose.

Also removes the redundant conftest.py sys.path mutation; pyproject.toml
already sets pythonpath = ["src"].

-
-```python
->>> Agent(name="x", instructions="i", run_on="e2b")
-TypeError: Agent(run_on='e2b') is not valid: run_on= places the whole agent
--- model calls, loop and tools -- on a managed runtime, and 'e2b' runs
-commands but cannot host an agent loop.
-  To run only the tools there:  Agent(tools_run_on='e2b')
-```
-
-To run one block of code somewhere else, name the place on that call:
-
-```python
-agent.execute_code_sync("print(6 * 7)", run_in="sandlock")   # kernel-enforced

-"""One vocabulary for "where does this run?", shared by Agent, AgentFlow and AgentTeam.
-
-Two questions get asked about placement and they have different answers:
-
-``run_on=``
-    Where the **whole agent** runs -- the model calls, the loop, the tools, all
-    of it on someone else's machine. Only a *managed runtime* can answer this,
-    because running the loop remotely means something has to host the loop.
-
-``tools_run_on=``
-    Where **the tools** run. Thinking stays on this machine; only the shell,
-    the file writes and the code execution move. Any sandbox or compute place
-    can answer this, because all it has to do is run a command.
-
-Keeping the two words apart is the entire point. The old surface used one word
-(``run_on=``) on ``AgentFlow``/``AgentTeam`` for the tools-only meaning, another
-(``compute=``) on ``LocalAgent`` for exactly the same meaning, and a third
-(``backend=``) for the whole-agent meaning -- so the same concept had two names
-and one name had two concepts.
-
-Because the two questions have disjoint answer sets, a wrong pairing is a typo
-worth catching rather than a preference worth honouring. ``run_on="docker"``
-cannot mean anything: Docker does not host agent loops. It gets a ``TypeError``
-naming the parameter the user actually wanted, not a silent fallback.

-"""Give a single Agent's tools a sandbox, without touching its thinking.
-
-``AgentFlow``/``AgentTeam`` already share one sandbox across a run and tear it
-down when the run ends. A lone ``Agent(tools_run_on=...)`` has no "run" to hang
-that lifetime on -- it is just an object someone calls ``chat()`` on, possibly
-many times -- so the sandbox is created on first use and lives as long as the
-agent does. That is deliberate: a file written in turn 1 is still there in turn
-2, which is what anyone who asked for a working directory expects.
-
-Attachment is idempotent and happens at the top of ``chat``/``achat``/
-``_start_stream``, and in ``AgentTeam`` before the task's tool list is
-snapshotted. Doing it once, rather than wrapping each call in a context
-manager, sidesteps two real hazards in this codebase:
-
-* ``_start_stream`` is a **generator**; a context manager around the call would
-  exit before the caller consumed a single token, tearing down the sandbox while
-  the model was still using it.
-* ``_start_stream`` falls back to ``self.chat``, so a wrapper would **re-enter**
-  itself and provision a second sandbox.
-
-Lifetime is tied to the agent by ``weakref.finalize`` rather than a process-exit
-hook over a weak set. The weak set leaked: an agent and its ``SharedCompute``
-reference each other, so a dropped agent was reclaimed by the cycle collector,
-vanished from the set, and its sandbox was never shut down. Gateways clone an
-agent **per request**, so that was one orphaned container per request.

-Work``) — so a compacted context keeps its structure instead of degrading to a
-one-line ``"Summary of N messages"`` count.
-
-Design: **deterministic, dependency-free, offline-safe.** It categorises the
-transcript into the template sections from the messages themselves (roles,
-tool calls, question marks, file-path tokens) rather than making an LLM call, so
-it never blocks the hot compaction path, never adds a runtime dependency, and
-never raises into the loop. File paths and identifiers are preserved verbatim.
-
-When an optional ``llm_summarize_fn`` is supplied the builder still renders the
-same template shape; on any failure it falls back to the deterministic render,
-honouring the issue's "fall back to the plain summary on failure" rule.
