Chris Amow 8c2ef80966 Remove the 4h timeframe
It was never in the enabled timeframes, so it held zero bars and produced no
levels, but it still carried weight 8 in the scoring table and forced
bucket_start to special-case a wall-clock ET anchor whose entire purpose was
surviving DST transitions. That was the most intricate logic in session.py,
maintained for a timeframe nobody used.

Daily is now the only session-anchored bucket, which is a much easier rule to
state and to keep correct. The DST parametrised tests go with it; the Sunday
open and daily boundary cases remain.

Manual-line tests move to 1h, so the weight assertions drop from 8 to 4.

The plan document keeps its 4h examples — rewriting a dozen illustrative
sentences would churn more than it clarifies — but the timeframe-roles section
now records the removal so nothing reads as a spec to build.
