Subject: [PATCH] docs(skills): drop the duplicated ASCII field-type decision
 tree
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`skills/objectstack-data/rules/field-types.md` carried a ~2.1 KB fenced ASCII
"Field Type Decision Tree" that re-listed the leaves of the same file's own
per-category tables. It taught nothing those tables do not already teach — each
`##` category heading answers the tree's top-level question and each row's
"When to Use" answers the leaf — and it was strictly less complete than them
(`slider` appeared in no branch). A mermaid rendering of the same tree already
ships to the same reader in the docs site.

The file is loaded whole into customer agent context on every session, so the
duplicate was billed per session, forever. Removing it frees real headroom in
the file's own density instead of taxing whichever unrelated sentence the next
author can spare.

Every table, the top-of-file blockquote and the `Common Field Configurations`
and `Incorrect vs Correct` sections are untouched; the change is a pure
deletion, no pointer line added.
