## Round ID
29336

## Description of the bug
It is possible to start growing an ovipositor while being in the 3x3 vicinity of a construction node.

For reference, you cannot ovi next to completed xeno constructions (recovery node, plasma tree, egg morpher, etc)

## What's the difference with what should have happened?
I expected not being able to.

## How do we reproduce this bug?
1) Start growing an ovipositor
2) Ask someone else to place a construction node next to you

## Attached logs
```
N/A
```

Start by tracing the ovipositor growth path and comparing its 3x3 proximity behavior with the checks used for completed xeno constructions. Reproduce the construction-node placement sequence described for round 29336, then verify that starting an ovipositor nearby is rejected.
