Reconcile operator copy contorted to dodge the now-removed banned words (D-225)

[StarshipSuperjam]

Design spec landed (engine-planning): decision-log.md D-225 ends banned-word-lists — the right word for the operator's need is the right word.

Problem

Operator-facing strings were written to avoid words the _FORBIDDEN tuples banned (e.g. structural / precedence / schema), sometimes at the cost of clarity. With the lists removed (see the word-ban-removal issue), restore the clearest wording.

Files (seed set — sweep for others)

• .engine/tools/tune.py — _REFUSE_STRUCTURAL, _REASSURANCE, and any operator string shaped to dodge a removed word.
• Any other operator-facing string contorted to avoid a now-allowed word.

Conforming target

Restore the clearest wording — the right word, plainly used, and explained where it carries weight the operator needs. Both edges of the operator-communication law apply: clarity over avoidance (substance), but never shorthand over substance — do not over-rotate into terse jargon just because the word-bans are gone. Conforming models in-repo: README.md, .engine/conduct/defaults.md ("You're technically literate, so I won't dumb things down").
