Summary

Fixes #1881 (run_code(timeout=N) enforced at ~2N) at the layer that owns the deadline, superseding the per-call-site write=0 approach in #1886.

pyqwest's httpx adapter has no deadline input: convert_timeout approximates an operation timeout as read + write (curioswitch/pyqwest#220) and ignores connect/pool. Every httpx.Timeout(x) the SDK builds (ApiClient's Timeout(config.request_timeout), envd file ops, the volume client, template uploads, code-interpreter's Timeout(timeout, connect=request_timeout)) was therefore enforced at 2x, while RetryableTransport._request_deadline budgeted min(phases) = x.

New leaf module e2b/deadline.py (import-cycle-free so e2b.retry can use it) defines the SDK rule once — the read phase of httpx.Timeout is the whole-request deadline:

request_deadline(extensions)        -> extensions["timeout"]["read"]  (None = unbounded)
with_request_deadline(extensions)   -> timeout={..., "read": d, "write": 0 if d is not None else None}

class PyqwestDeadlineTransport(PyqwestTransport):          # + Async twin
    def handle_request(self, request):
        request.extensions = with_request_deadline(request.extensions)
        return super().handle_request(request)

• get_httpx_transport (sync/async) and the inline template-upload transports now build PyqwestDeadlineTransport / AsyncPyqwestDeadlineTransport, so all shared httpx consumers get Timeout(x) → x with no call-site changes.
• _request_deadline in e2b/retry.py uses request_deadline, so the retry budget equals the enforced deadline (Timeout(300, connect=60) → 300, not 60).
• code-interpreter: replaced the stale "takes the longest phase" comment, and request_timeout=0 on run_code/create_code_context now disables the timeout via ConnectionConfig.get_request_timeout instead of request_timeout or default (pre-existing nit from the fix(code-interpreter): abort Jupyter requests at the requested deadline #1886 review).

The rewrite deliberately encodes pyqwest's current sum rule in one place; once pyqwest exposes an explicit operation-timeout extension, with_request_deadline becomes a one-line change.

Tests: tests/test_request_deadline.py — pure mapping/retry-budget cases plus a stalling local HTTP server proving sync and async ApiClient (request_timeout) and envd (Timeout(d, connect=60)) requests fail at ~d rather than 2d, and Timeout(None) still waits.
