feat(051-implement-real-task-function-dispatch-in-wfexec-cu): Implement real task function dispatch in wf_exec. Currently lookup_task_function/2 is a hardcoded mock that ignores the task name and returns fun(Ctx) -> {ok, maps:put(task_result, ok, Ctx)} end. Fix this so the executor actually calls the task function from the wf_term metadata. The compiler must propagate task metadata (the function field from task_metadata map) into the bytecode or a side-table accessible by the executor. The executor must call the real function when it encounters a task_exec opcode. ACCEPTANCE TEST: Create an escript that compiles wf_term:seq(wf_term:task(a, #{function => fun(Ctx) -> {ok, Ctx#{a_ran => true}} end}), wf_term:task(b, #{function => fun(Ctx) -> {ok, Ctx#{b_ran => true}} end})), executes it, and asserts the final context contains both a_ran and b_ran keys set to true. The test must fail with the current mock and pass after the fix. Do NOT use mocks or stubs. Write a real eunit test in test/wf_acceptance_tests.erl that verifies this.

The root cause is wf_trace:new/1 creates a named ETS table wf_trace_events — when multiple tests call new/1, the second call crashes with badarg (table already exists). Fix wf_trace:new/1 to delete existing table first or use ets:whereis to check. Also fix assertion mismatches in trace_level_full_test, sink_ets_test, snapshot_serialization_test, restore_bytecode_mismatch_test, restore_invalid_binary_test, filter_scope_test, filter_predicate_test, integration_wf_exec_emits_events_test.
