* feat(reconciliation): close the bank-feed loop on voucher links and re-tag mis-typed opening balances

Two related fixes to bank reconciliation correctness:

1. Auto-reconcile on voucher link. Linking an invoice or supplier invoice to
   an existing voucher previously advanced only the invoice — the bank
   transaction that paid it kept sitting in the Transactions inbox with a null
   journal_entry_id. linkInvoiceToVoucher / linkSupplierInvoiceToVoucher now
   call autoReconcileTransactionForLinkedVoucher (lib/reconciliation), which
   links the bank transaction to the same verifikat when exactly one unbooked
   line matches it. Best-effort and post-commit: a failure here never fails the
   link. The result surfaces reconciledTransactionId; the inbox row leaves the
   list and the UI shows link_success_tx_reconciled.

2. Re-tag mis-typed opening balances. getReconciliationStatus and the GL-line
   matching RPCs identify a cash account's ingående balans solely by
   journal_entries.source_type='opening_balance'. Companies migrated from other
   systems often booked the bank IB as an ordinary voucher (source_type
   'import' or 'manual'), so it was never excluded and surfaced as a phantom
   reconciliation difference equal to the opening balance. Adds:
   - migration mark_entry_as_opening_balance: a GUC-gated carve-out in the
     immutability trigger plus a SECURITY DEFINER RPC that validates the entry
     (balance-sheet lines only, dated on a fiscal-period boundary), flips the
     source_type, and writes an audit row — no blanket data sweep.
   - POST /api/reconciliation/bank/mark-opening-balance + MarkOpeningBalanceSchema.
   - BankReconciliationView action to trigger it from the IB diff.

The gnubok_create_voucher executor now accepts a typed is_opening_balance flag
and derives source_type='opening_balance' only after validating class 1/2 lines
on the period start, so new IBs land correctly typed.

Covered by lib/reconciliation auto-reconcile tests, voucher-executors tests,
and a mark-entry-as-opening-balance pg-real test.

* chore: rebrand gnubok → Accounted and prune swarm agent skills

Product rebrand and skills housekeeping. No runtime behaviour change.

Rebrand: replace user-visible "gnubok" with "Accounted" across docs, READMEs,
in-code comments, doc-site content, MCP skill/resource prose, and the
gnubok-mcp package description. The MCP resource URI scheme is moved gnubok://
→ Accounted:// consistently across resource registrations, the event-type
comment, and the resource/skill tests. Deliberately preserved as stable
identifiers (NOT rebranded): the gnubok-company-id cookie, gnubok_sk_ / gnubok_inv_
token prefixes, the gnubok-mcp npm bridge name, and the AGI <gem:Programnamn>
value (kept 'gnubok' per its source comment — it is the software identifier sent
to Skatteverket and must not churn across visual rebrands).

Skills: remove the 27 swarm-* agent SKILL.md atoms (no longer used; already
absent from the agent_atom_registry in prod), refresh the remaining skill docs,
add the .claude/rules/ path-scoped rule set, and regenerate the
seed_agent_atom_bodies migration + .skill-body-manifest.json via
`npm run skills:generate` so the DB-backed skill bodies match the trimmed set.

# Bookkeeping Domain Reference
For Swedish accounting-law questions, use the domain skills (`swedish-vat`, `swedish-accounting-compliance`, `swedish-year-end-closing`, etc.). The accounting guard rails in the root `CLAUDE.md` always apply.
## Core Services (`lib/core/`)
- `bookkeeping/period-service.ts` — Fiscal period lifecycle management (open, close, lock)
- `bookkeeping/year-end-service.ts` — Year-end closing procedures
- `bookkeeping/storno-service.ts` — Reversal/correction entry generation
- `tax/tax-code-service.ts` — Tax code definitions and rates
- `audit/audit-service.ts` — Audit trail and compliance logging
- `documents/document-service.ts` — Document attachment lifecycle (WORM storage with version chains)
## Key BAS Accounts
`1510` Accounts receivable | `1930` Business bank account | `2013` Private withdrawals (EF) | `2440` Accounts payable | `2611`/`2621`/`2631` Output VAT 25%/12%/6% | `2641` Input VAT | `2645` Calculated input VAT (EU) | `2893` Shareholder loan (AB) | `3001`/`3002`/`3003` Revenue 25%/12%/6% | `3305`/`3308` Export/EU service revenue
BAS data (`lib/bookkeeping/bas-data/`): full BAS 2026 chart by class (1–8) + SRU mapping. Account numbers are **strings** (`'1930'`, never `1930`).
## VAT Treatments
`standard_25`, `reduced_12`, `reduced_6`, `reverse_charge`, `export`, `exempt`
Invoice items support individual `vat_rate` values (mixed-rate invoices). Use `getAvailableVatRates(customerType, vatNumberValidated)` from `lib/invoices/vat-rules.ts`. VIES validation via `lib/vat/vies-client.ts`.
## VAT Declaration Rutor (SKV 4700)
`VatDeclarationRutor` type maps to momsdeklaration:
- **Ruta 05**: Domestic taxable sales (3001+3002+3003)
- **Ruta 06/07**: Unused, always 0
- **Ruta 10/11/12**: Output VAT 25%/12%/6% (2611/2621/2631)
- **Ruta 39/40**: EU services / Export (3308/3305)
- **Ruta 48**: Input VAT (2641/2645)
- **Ruta 49**: Moms att betala/återfå = (10+11+12+30+31+32+60+61+62) − 48
