Set up Sage Intacct projects and tasks without duplicates

**Objective:** Set up the project `{project-name}` for the customer `{customer}` (blank for an internal project), managed by `{project-manager}`, with these tasks: {tasks}. Check for an existing project first, and get the user's confirmation before writing.

**Step 1: Check it does not already exist**

Call `intacct-get-project` with `project-name.contains` set to the project name. If a project with the same or a very similar name exists, show it and stop unless the user confirms this is a different project.

**Step 2: Resolve the people**

* Customer: call `intacct-get-customer` with `customer-name.contains`. It must resolve to exactly one active customer; take its `customer-id`.
* Manager: call `intacct-get-employee` with `employee-name.contains`. It must resolve to exactly one active employee; take its `employee-id` as the manager ID.
* Several matches for either: list them and stop.

**Step 3: Settle the values**

* Category is required. Pick one from the values the `category` parameter lists: a contract or billable category when there is a customer, an internal one when there is not. If no values are listed, ask the user.
* Task status is required on every task. Call `intacct-get-task` with `max-records` 20 to see the `task-status` values in use, and use the one that means not started.
* Start date: today unless the user gave one. The tools take MM/DD/YYYY.
* Leave the project ID blank so Intacct numbers it, unless the user gave one.
* Split the tasks on commas. If there are more than 10, confirm the list with the user first.

**Step 4: Confirm**

Show the project name, category, customer and ID, manager and ID, start date, and the task list. Wait for an explicit yes.

**Step 5: Create the project**

Call `intacct-create-project` once. It does not return an ID, so call `intacct-get-project` with `project-name` set to the exact name to get the new `project-id`. If it cannot be found, stop: do not create tasks, and do not create the project again.

**Step 6: Create the tasks**

For each task, call `intacct-create-task` once with the `project-id`, the task name and the task status. If one fails, carry on with the rest and report which failed.

**Step 7: Verify and report**

Call `intacct-get-task` with the `project-id`, and report the project ID and the tasks that now exist.

**Rules & Guidelines:**

* The only writes are `intacct-create-project` once and `intacct-create-task` once per listed task, all after the user confirms.
* Do not call `intacct-update-project` or `intacct-update-task`. Both need a record number that no read tool on this server returns, so a mistake has to be fixed in Intacct directly. Say so if one happens.
* Do not call `intacct-create-customer` for a missing customer. Stop instead.
* If the user names an Intacct company, pass it as `company` on every call.

**Validation:**

* If the customer or manager is not found, say which and stop.
* If no tasks were given, create the project only.
