feat(cortex): Epic 2 - @Mention Systeem (E2.S1-S3)

Inline patient selectie via @naam in de chat input. YAGNI Versimpeling: 8→4 SP, 5→3 stories - Geen selectedMentions array (activePatient is al beschikbaar) - Geen API payload wijziging nodig - Geen meerdere mentions tracking E2.S1 - @-detectie: - Detecteer laatste @ in input - Track query en startIndex - Actief als geen space na @ en minimaal 1 char E2.S2 - PatientMentionDropdown: - Hergebruik usePatientSearch (debounce 150ms, limit 5) - Hergebruik PatientListItem (size="sm") - Positioned above input (bottom-full) - Escape sluit dropdown E2.S3 - Selectie flow: - Vervang @query met @naam in input - Zet activePatient via usePatientSelection - Sluit dropdown automatisch Bouwplan v1.4: Epic 2 compleet (14/19 SP - 74%) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
