Fix a cutover difference with one confirmed entry

**Objective:** Make Intacct account `{account-number}` match its Dynamics GP balance at `{cutover-date}` with one journal entry against clearing account `{clearing-account}`, after the user confirms it.

**Step 1: GP balance**

Ask the user for the GP fiscal year and the last GP period before cutover, unless they are already stated in this conversation. Call `dynamics-gp-get-gl-account-summary` with `main-account-segment` = `{account-number}` and that `year`. For a balance sheet account add `period-balance` for period 0 through the cutover period; for a Profit and Loss account add periods 1 through the cutover period. Use debit-positive amounts.

**Step 2: Intacct balance**

Call `intacct-get-account` for `{account-number}` and for `{clearing-account}`; if either does not exist, stop. Call `intacct-get-general-ledger-detail` with `account-number` = `{account-number}` and `entry-date.to` = `{cutover-date}` (for an income statement account, from the fiscal year start), and net `debit-amount` minus `credit-amount`.

**Step 3: Propose**

Difference = GP balance minus Intacct balance. If it is under 0.01, say the account already ties and stop. Otherwise propose:
* `posting-date`: `{cutover-date}` as MM/DD/YYYY.
* `journal`: GJ unless the user names another.
* `title`: "GP conversion adjustment {account-number}".
* A positive difference debits `{account-number}` and credits `{clearing-account}`; a negative one does the reverse. `debit-amount` and `credit-amount` are both the absolute difference.
* `state`: draft, unless the user asks to post.

Show the GP balance, the Intacct balance, the difference and the entry, and ask for confirmation.

**Step 4: Post**

Only after confirmation, call `intacct-create-journal-entry` once. If it fails (for example the period is closed), report the error and stop; do not retry with another date.

**Step 5: Confirm**

Call `intacct-get-journal-entry` for the new entry, then recompute the Intacct balance as in Step 2 and report whether the account now ties.

**Rules & Guidelines:**

* Tools prefixed dynamics-gp- are on the dynamics-gp MCP server. Tools prefixed intacct- are on the intacct MCP server. Both servers must be connected; if a tool from either is missing, say which server is not connected and stop.
* Pass `{gp-company}` as `company` on every dynamics-gp- call (empty means the default GP company). Use the default Intacct company; if the Intacct side holds several entities and it is not clear which one received this GP company, ask before starting.
* Set `max-records` high (5000) on every list read. If a read returns exactly that many rows, say the result may be truncated and narrow the filter (per account, per vendor, per customer or per item) instead of reporting totals from it.
* One write only: `intacct-create-journal-entry`, once, after confirmation. Never call `intacct-update-journal-entry`. Never write to GP: do NOT call `dynamics-gp-gl-account-transaction-add`.

**Validation:**

* Refuse if `{account-number}` and `{clearing-account}` are the same account.
* If the difference is large relative to the balance (over 10 percent), say so and suggest running reconcile-trial-balance-at-cutover first, since a mapping error is more likely than a missing balance.
