memory replace/remove target an entry by old_text but supply the replacement
via content — an asymmetric pairing. Callers naturally reach for new_text to
mirror old_text (it's exactly the patch tool's old_string/new_string shape),
which left content empty and errored 'content is required'. The failure also
rendered tersely, making the cause easy to miss and costing a retry.
Accept new_text as an alias for content on both shapes:
- single-op: coalesce content = content or new_text in memory_tool() + a
new_text param wired through the registry handler.
- batch ops: content = op.content or op.new_text (and in the approval-gate
preview builder).
- schema: document the alias on content and add a new_text property to the
single-op params and batch item props so strict validators accept it.
content wins if both are set.
Tests: new_text alias on single add/replace, batch add/replace, and
content-wins-over-new_text. 43/43 across memory tool + schema suites.
