## Problem
Sentry `TWENTY-SERVER-G4F` — `Error: Operand IS not supported for this
filter type` (30k+ occurrences, 15 workspaces, ongoing).
A workflow **Filter** step throws when a step filter carries an
`IS`/`IS_NOT` operand on a text/array field type (`TEXT`,
`MULTI_SELECT`, `EMAILS`, `PHONES`, `ADDRESS`, `LINKS`, `FULL_NAME`,
`ARRAY`, `RAW_JSON`). `evaluateTextAndArrayFilter` only handled
`CONTAINS`/`DOES_NOT_CONTAIN`/`IS_EMPTY`/`IS_NOT_EMPTY` and hit
`default:` → `throw`. The throw propagates out of `FilterWorkflowAction`
and **fails the entire workflow run**.
The current frontend no longer offers `IS`/`IS_NOT` for these types, so
these are **legacy persisted step filters** in older (immutable)
workflow versions that keep executing.
## Fix
Handle `IS`/`IS_NOT` in `evaluateTextAndArrayFilter` as
`contains`/`!contains`, consistent with `evaluateSelectFilter` (chosen
over strict equality because the routed types include arrays/composites
where `==` would silently never match). No existing operand behavior
changes.
## Tests
Added coverage for legacy `IS`/`IS_NOT` on `TEXT` and `MULTI_SELECT`.
Note: the pre-existing `date operands` test failures are
timezone-dependent and unrelated to this change (they fail on `main`
too).
Fixes TWENTY-SERVER-G4F
