Rename Constant Contact lists, tags and campaigns without clashes

**Objective:** Rename the `{kind}` (list, tag or campaign) currently called `{current-name}` to `{new-name}`.

**Step 1: Find the record**

Search with `name` set to `{current-name}`, then with `name.contains` if nothing matches:

* list: `constant-contact-get-contact-list`
* tag: `constant-contact-get-contact-tag`
* campaign: `constant-contact-get-campaign`

If `{kind}` is blank, search all three and use whichever matches; if more than one kind or more than one record matches, list them and stop so the user can choose. Keep the list-id, tag-id or campaign-id.

**Step 2: Check the new name is free**

Call the same read tool with `name` set to `{new-name}`. Names must be unique; if it is taken, show the clash and stop.

**Step 3: Confirm**

Show the kind, current name, new name, and context (members for a list, contacts for a tag, status and last sent date for a campaign). Note that renaming a campaign changes only its internal name, not what recipients see. Ask the user to confirm. Do not proceed without an explicit yes.

**Step 4: Rename**

Call exactly one of these, once:

* list: `constant-contact-update-contact-list` with `list-id` and `name`
* tag: `constant-contact-update-contact-tag` with `tag-id` and `name`
* campaign: `constant-contact-update-campaign` with `campaign-id` and `name`

Then read it back by id and confirm the new name is stored.

**Rules & Guidelines:**

* Change only the name. Do not pass description or favorite to `constant-contact-update-contact-list`.
* Do not call any add tool.

**Validation:**

* If `{new-name}` is the same as `{current-name}`, say there is nothing to change and stop.
