feat(salary): agent path to set this month's per-run salary (#2015)

* feat(salary): agent path to set this month's per-run salary Agents could not do variable owner pay: the only per-run edit tool, gnubok_update_payslip_line, edits the display-only Grundlon line that every recalculation rebuilds from salary_run_employees.monthly_salary, so the fixed employee salary silently won (user-reported). - lib/salary/run-employees.ts: setRunEmployeeSalary() shared service (draft gate, roundOre, 0 = nollkorning, display-line refresh); the cookie route PATCH now delegates to it (behavior unchanged) - MCP: gnubok_set_run_salary staged tool (search catalog: tools/list budget at zero headroom), op type set_run_salary (medium risk), commitSetRunSalary executor, payroll:write scope, payroll_month loadout + payroll-monthly skill step; update_payslip_line description now warns that recalc rebuilds base salary lines - v1 REST: PATCH /salary-runs/{id}/employees/{employeeId} accepting monthly_salary (draft only, dry-run, idempotency key) - Migration pair (NOT VALID + VALIDATE) adds set_run_salary to the pending_operations op-type CHECK; base list verified against prod live - Tests: service, staged tool, executor, cookie route, v1 route; spec snapshot updated Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01MP37pE3zk667nP6S766iJG * fix(salary): harden set_run_salary per skeptic + CI findings - Clear calculation_breakdown when the per-run salary changes so the existing book preflights force a recalculation: a run can no longer be booked with gross/tax derived from the old salary (skeptic R1) - Enforce SALARY_OVERRIDE_MAX (10 MSEK) in the shared service and the v1 body schema: closes the unbounded/1e307-overflow path that wrote Infinity -> NULL -> 500 (skeptic R2) - Promote gnubok_set_run_salary to the default catalog: a search-only WRITE is uncallable on Claude.ai (update_customer lesson) while three surfaces pointed agents at it; payload ceiling bumped 63.8K -> 64.4K with a ledger entry, read-demotion left as its own change (skeptic R3) - Granskning label type_set_run_salary in vocabulary.ts + sv/en (R4) - Display-line refresh is fire-and-forget again (write already committed; matches pre-refactor route behavior) and DB error details carry the SQLSTATE code for Swedish error mapping - v1 risk metadata aligned to 'medium'; NOT_DRAFT message now covers salary edits, not just roster changes - npm run apiskill:generate committed (CI apiskill:check failure) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01MP37pE3zk667nP6S766iJG * chore(migrations): rename set_run_salary pair past main's newest versions origin/main gained 20260828120000 and 20260828154800 after this branch staged 20260828110000/1; out-of-order versions are skipped at merge, so the pair moves to 20260828160000/1 (byte-identical SQL, reference in the VALIDATE header updated).
