fix(events): log full exception details in ReactiveEventBus.emit() error handler
Add exc_info=True to the _logger.warning() call in the per-handler
exception block of ReactiveEventBus.emit().  The handler already logged
error=str(exc) (the exception message text), but omitted the traceback.
With exc_info=True structlog now forwards the full traceback to the
configured log output, giving developers the diagnostic detail needed
to debug subscriber failures in production.

Remove the @tdd_expected_fail tag from the traceback scenario in
features/tdd_event_bus_exception_swallow.feature so that both TDD
scenarios (#988) run as normal regression guards.

Fix TDD tags in robot/tdd_e2e_implicit_init.robot: replace incorrect
tdd_bug/tdd_bug_1023 tags with the canonical tdd_issue/tdd_issue_1023/
tdd_expected_fail tags so the tdd_expected_fail_listener properly
inverts results while bug #1023 remains open.

Feature: TDD Issue #988 — ReactiveEventBus.emit() swallows exception details
As a developer debugging a subscriber failure
I want the exception handler in ReactiveEventBus.emit() to log the full
exception message and traceback
So that I can diagnose why a subscriber failed without guessing
This test captures bug #988. The exception handler in
ReactiveEventBus.emit() currently logs only `type(exc).__name__`
(e.g. "ValueError") without `str(exc)` or `exc_info=True`. When a
subscriber raises, the log contains no diagnostic detail no message,
no traceback, no clue about which input or state caused the failure.
The traceback scenario uses `@tdd_expected_fail` because that
assertion still FAILS while the bug exists. The tag inversion
mechanism causes CI to report that scenario as passed. Once the
fix for #988 is merged, the `@tdd_expected_fail` tag must be
removed so both scenarios run normally.
See CONTRIBUTING.md > Bug Fix Workflow > TDD Issue Test Tags.

Scenario: Bug #988 — emit() logs exception message when handler raises
Given a ReactiveEventBus with a handler that raises a ValueError
When I emit an event that triggers the failing handler
Then the warning log should contain the exception message text
Scenario: Bug #988 — emit() logs traceback via exc_info when handler raises
Given a ReactiveEventBus with a handler that raises a ValueError
When I emit an event that triggers the failing handler
Then the warning log should contain traceback information
