chore: bump version to v0.1.106

La bascule app:rtt:rollover ne reprenait que les RTT acquis de l'exercice qui
se terminait : le report d'ouverture déjà présent était perdu et les paiements
n'étaient pas déduits. Le nouveau report reprend le solde de clôture =
report d'ouverture(N-1) + acquis(N-1) − RTT payés(N-1), soit le "Disponible"
affiché par EmployeeRttSummaryProvider.

- nouveau RttClosingBalanceService (fold pur testé : invariant somme tranches =
  disponible, cascade déficit 50% avant 25%, récup CUSTOM non perdue)
- RttRolloverCommand branché dessus + option --recompute (écrase les lignes
  existantes non verrouillées, pour reprise d'une bascule erronée)
- test date-sensible EmployeeRttSummaryProviderTest rendu robuste
- docs: doc/rtt-rollover.md, CLAUDE.md, documentation-content.ts

+## Rollover RTT (cron `app:rtt:rollover`)
+- Bascule le **1er juin** (idempotente) : crée la ligne `employee_rtt_balances` du nouvel exercice (`targetYear`) pour chaque employé éligible (ni INTERIM, ni PRESENCE).
+- **Report = solde de clôture de l'exercice N-1**, pas seulement l'acquis : `report_ouverture(N-1) + acquis(N-1) − RTT payés(N-1)`. C'est exactement le **disponible** affiché par `EmployeeRttSummaryProvider` (`carry + currentYearRecovery − totalPaid`). Le report stocké pour N reprend donc le disponible de fin N-1 ; le report déjà présent en début d'année n'est jamais perdu, et les heures payées ne sont pas re-créditées.
+- Service mutualisé : `App\Service\Rtt\RttClosingBalanceService` (méthode `computeClosingBalance` + `fold` pur testable). `fold` garantit `somme(tranches) = report + acquis − payés` ; la cascade des semaines déficitaires draine la tranche 50% avant la 25%, et la récup non bucketisée (CUSTOM 1h=1h, arrondis) atterrit en `base25` pour que la somme égale le total.
+- Options : `--force` (hors 01/06) ; `--recompute` (recalcule/écrase les lignes existantes au lieu de les sauter ; **ne touche jamais** une ligne verrouillée `is_locked`). Reprise d'une bascule erronée : `app:rtt:rollover --force --recompute`.
+- ⚠️ Bug historique : la 1ʳᵉ version ne reportait que `acquis(N-1)` (report d'ouverture perdu, paiements non déduits). Corrigé via `RttClosingBalanceService`.
+- Doc : `doc/rtt-rollover.md`.

 ## Vue contrat (sélecteur de phase)
 - Picker `Vue contrat` en haut de la fiche employé (`pages/employees/[id].vue`). Caché si l'employé n'a qu'une phase.
 - Phase = groupe d'`EmployeeContractPeriod` consécutifs partageant la signature `(contract.type, weeklyHours, isDriver)`. Résolu par `App\Service\Contracts\EmployeeContractPhaseResolver`.
