            WHAT IT DOES:
            Creates a brand-new campaign that is a DEEP COPY of an existing one. The new
            campaign is created in DRAFT status and spends no budget. This mirrors the
            platform UI's "Duplicate campaign" action.

            WHAT GETS COPIED (server-side, automatic — there are NO toggles to choose):
            - Goal (Lead Gen / Brand Awareness)
            - Optimization (budget) group / tag
            - All landing pages
            - Every channel that is currently ENABLED FOR THE ACCOUNT, together with that
              channel's audiences, ads/creatives, keywords, offers and bid settings.
              (Channels that are disabled for the account are skipped — connect/enable the
              channel on the account first if you need it carried over.)

            WHAT IS NOT COPIED / CHANGES:
            - The new campaign starts in DRAFT (the original's live/active state is NOT copied).
            - Start/end dates are not carried as a live schedule — set them on the new draft.
            - Only the new name is caller-controlled.

            REQUIRED PARAMETERS:
            - campaign_id (integer): The wizard/campaign ID of the campaign to duplicate.
              Must be in status Launched, Launching, Editing, or Draft.

            OPTIONAL PARAMETERS:
            - name (string): The name for the NEW campaign. Must be non-blank, <= 255 chars,
              and UNIQUE across the account's campaigns. If omitted, a unique name is
              auto-generated as "<original name>_copy_<UTC timestamp>" (e.g.
              "Q1_2026_Campaign_copy_20260115120000"). If you pass a name that
              already exists on the account, the platform rejects it — choose a unique name
              or omit it to auto-generate one.

            CAMPAIGN ID SOURCES:
            - search_campaigns_by_names tool (recommended)
            - list_wizard_campaigns tool
            - get_campaign_by_wizard_id tool

            WORKFLOW:
            1. Find the source campaign ID (search_campaigns_by_names / list_wizard_campaigns).
            2. duplicate_campaign(campaign_id=..., name="..."  # name optional).
            3. The response contains the NEW campaign's id and full configuration.
            4. Review the new DRAFT campaign and MODIFY it with the edit tools below (it is a
               normal editable draft — change anything you want).

            AFTER DUPLICATING — HOW TO MODIFY THE NEW DRAFT:
            The copy is a regular DRAFT campaign, so use the standard campaign-editing tools on
            the NEW campaign id (NOT the original). The main ones:
            - add_and_edit_campaign_elements — the primary editor: rename, change budget group,
              start/end dates, enable channels, replace per-channel offers, and ADD audiences,
              exclusion audiences, ads, ad groups, and keywords. (Native / N×N×N campaigns:
              use add_and_edit_native_campaign_elements.)
            - update_experiments_daily_budgets — adjust per-experiment daily budgets.
            - update_reddit_channel_settings — Reddit-specific channel/bid/pixel settings.
            - remove_channels_from_campaign / remove_audiences_from_campaign /
              remove_ad_from_campaign / remove_keywords_from_campaign /
              remove_offers_from_campaign / remove_target_groups_from_campaign
              — remove elements from the copy.
            - manage_campaign — pause/restart (lifecycle).
            Tip: call get_campaign_by_wizard_id on the new id first to see what was copied,
            then edit. Use search_campaigns_by_names to re-locate the copy by its new name.

            EXAMPLE:
            User: "Make a copy of campaign 54050 called 'Q2 Relaunch'"
            Call: duplicate_campaign(campaign_id=54050, name="Q2 Relaunch")
            Then: add_and_edit_campaign_elements(campaign_id=<new id>, ...) to tweak the copy.

            RESPONSE FORMAT:
            Returns the full configuration of the newly created DRAFT campaign — including its
            new campaign id, name, status (Draft), goal, optimization group, and copied channels.
            Use the returned id with get_campaign_by_wizard_id and the edit tools.

            Anchor any date-derived naming to the REAL current date — call get_current_date if unsure.
