Make the double tap a stance that holds the net

Oliver on v376: "wenn man doppeltippt, geht er minimal vor". His own
ball's flight covered 4-9 m of the 10 to the net. His next ball was met
from mid-court, outside the net zone, and the recovery after that volley
walked him straight back to the baseline.

The double tap now sets a stance (P.post) that lasts until the next
double tap, a lob he has to run down, or the end of the point. Every
recovery heads for the net at full pace, and every incoming ball is
planned as a net man's. The 'back' stance clears once he is behind the
net zone, so short balls still pull him in.

Measured: contacts while committed are ~35% at the net and ~40% around
the service line, and he no longer falls back. The base ladder is
unchanged. New test; v377.

+### The double tap is a STANCE, not one ball's run (2026-10-14, v377)
+Oliver on v376: *"funktioniert irgendwie nicht — wenn man doppeltippt, geht er minimal vor"*. **Measured**
+(`NETX=1`, the bot double-tapping behind 100% of its deep flicks):
+- His own ball's flight covered only 4-9 m of the ~10 m to `netStand`.
+- His next ball was usually met from mid-court, 7-10 m out, which is OUTSIDE `netFrom` (7 m).
+- The approach flag lived for one ball, so the recovery after that volley (`rallyHome`: outside the net
+  zone → baseline) walked him straight back. Forward a little, then back: exactly the report.
+
+**Now `P.post`** ('net' / 'base') is set by the double tap and holds:
+- 'net' lasts until the next double tap, a lob he cannot get under and runs down (`plan.over === null` →
+  'base'), or the point's end (`setupPoint` clears it).
+- `atNetHome` reads it first for the player, so every recovery heads for `netStand` at full pace.
+  `P.rushing` follows it, so every incoming ball is planned as a net man's.
+- 'base' clears itself once he is back beyond `netFrom` + 0.5, so a short ball still pulls him in as before.
+
+**After:** of his contacts while committed, ~35% are at the net (< 3.5 m), ~40% around the service line (the
+first volley), ~20% at 7-10 m, and ~5% further. The stance is dropped only by lobs and point ends. Ladder
+(σ60, 8 seeds): the base is unchanged; following in is now about neutral, still good against the pushers
+(Steward 52 → 61), and no longer punished by the Brute and the Champion.
+Test: committed to the net, a volley struck 9 m out keeps him coming in (< 7 m a second later); without the
+stance the old recovery still takes him back.
