feat(horatio): add Horatio actor script memorization app

Two-package monorepo:
- horatio_core: pure Dart package (parser, SRS, planner)
- horatio_app: Flutter UI (Bloc/Cubit, GoRouter, TTS)

Features:
- Script import (txt, docx, pdf) with drag-and-drop
- Four script format parsers (colon, bracketed, parenthetical, screenplay)
- SM-2 spaced repetition for line memorization
- Rehearsal mode with TTS and line comparison
- 5 bundled public domain scripts

Quality:
- 83 core tests + 160 app tests, both 100% branch coverage
- Strict analysis (130+ lint rules, fatal-infos)
- Dead code detection script (dead_code.sh)
- run.sh pipeline: analyze, test, dead-code, run, web
- Pre-commit hook for horatio test coverage

+# Horatio — Script Memorization App Design Spec
+
+## Overview
+
+**Horatio** is a multiplatform app (iOS, Android, Windows, Linux, macOS) for actors
+to learn their scripts through structured rehearsal and spaced repetition.
+
+Named after Hamlet's loyal friend — the faithful companion who helps you remember.
+
+## Architecture
+
+**Two-package monorepo managed by Melos:**
+
+- `horatio_core` — Pure Dart package: script parsing, models, SM-2 SRS, memorization planner
+- `horatio_app` — Flutter app: UI, TTS, audio, Bloc/Cubit state management, drift database
+
+## Tech Stack
+
+- **Framework:** Flutter 3.x (Dart 3.x)
+- **State management:** Bloc/Cubit
+- **Database:** SQLite via drift (type-safe, reactive, migrations)
+- **TTS:** System TTS via flutter_tts (offline)
+- **Monorepo:** Melos
+- **Lint:** Strictest possible dart analysis + DCM + pre-commit hooks
+
+## Core Models
+
+- `Script` — Full parsed document (title, scenes, roles, lines)
+- `Role` — Character name + all their lines
+- `ScriptLine` — Text content, role, scene index, position, optional stage direction
+- `Scene` — Ordered list of lines with scene title
+- `SrsCard` — Line/cue pair with SM-2 data (interval, ease factor, next review date)
+- `RehearsalSession` — Progress through a dialogue sequence
+
+## Screen Flow
+
+1. **Home** — Imported scripts list + public domain library + import button
+2. **Import** — File picker for PDF/DOCX/TXT/ODS, parsing progress
+3. **Role Selection** — Detected roles with line counts, deadline picker
+4. **Schedule Overview** — Calendar of daily memorization sessions
+5. **Dialogue Rehearsal** — TTS reads others' lines, actor types their response
+6. **SRS Review** — Flashcard interface with SM-2 scheduling
+
+## Script Parsing
+
+**Supported formats:** TXT, PDF, DOCX, ODS
+
+**Role detection heuristics (priority order):**
+
+1. Screenplay format: `CHARACTER NAME` in ALL CAPS on its own line
+2. Colon format: `CHARACTER: dialogue text`
+3. Parenthetical: `CHARACTER (stage direction) dialogue`
+4. Bracketed: `[CHARACTER] dialogue`
+
+**Edge cases:** Stage directions preserved but not treated as dialogue. Cross-page
+line merging. Narration tagged as STAGE_DIRECTION.
+
+## SM-2 Spaced Repetition
+
+Standard SM-2 algorithm:
+
+- Each line/cue pair becomes an SRS card
+- New cards introduced per deadline schedule
+- Review intervals adjusted by ease factor (1.3 minimum)
+- Long monologues split into sentence-pair cards
+
+## Dialogue Rehearsal Mode
+
+- Sequential scene playback
+- Other characters' lines read by TTS
+- Actor types their line at each cue
+- Levenshtein distance for fuzzy matching
+- Diff highlighting for feedback
+- Session progress feeds into SRS scheduling
+
+## Public Domain Library
+
+Pre-parsed scripts bundled as JSON assets:
+
+- Shakespeare: Hamlet, Romeo and Juliet, Macbeth, A Midsummer Night's Dream,
+  Othello, The Tempest
+- Chekhov: The Cherry Orchard, Three Sisters, The Seagull, Uncle Vanya
+- Molière: Tartuffe, The Misanthrope
+- Oscar Wilde: The Importance of Being Earnest
+- Ibsen: A Doll's House, Hedda Gabler
+
+## Code Quality
+
+- Strictest dart analysis (strict-casts, strict-inference, strict-raw-types)
+- 50+ lint rules enabled
+- dart_code_metrics for complexity limits
+- Pre-commit hooks: analyze, format, test
+- Coverage: 100% on core, 90%+ on app
+- Melos for consistent cross-package commands
+
+## MVP Phases
+
+**Phase 1 (MVP):** Import, role detection, rehearsal mode, SRS cards, schedule
+**Phase 2:** Audio recording, performance notes, stress annotations, public domain browser

To die, to sleep;\nTo sleep, perchance to dream — ay, there's the rub.\n\n(Enter Ophelia)\n\nOPHELIA: Good my lord,\nHow does your honour for this many a day?\n\nHAMLET: I humbly thank you; well, well, well.\n\nOPHELIA: My lord, I have remembrances of yours,\nThat I have longed long to re-deliver;\nI pray you, now receive them.\n\nHAMLET: No, not I;\nI never gave you aught.\n\nOPHELIA: My honour'd lord, you know right well you did;\nAnd, with them, words of so sweet breath composed\nAs made the things more rich: their perfume lost,\nTake these again; for to the noble mind\nRich gifts wax poor when givers prove unkind.\nThere, my lord.\n\nHAMLET: Ha, ha! are you honest?\n\nOPHELIA: My lord?\n\nHAMLET: Are you fair?\n\nOPHELIA: What means your lordship?\n\nHAMLET: That if you be honest and fair, your honesty should\nadmit no discourse to your beauty."
