feat: code quality improvements (#10, #12, #13)

- Extract matching strategies into strategies.py module (#10)
  * DurationMatchStrategy: match files by runtime similarity
  * SequentialStrategy: fill remaining gaps in order
  * DiscMappingStrategy: explicit disc-to-episode mapping
  * ConstraintAwareStrategy: validate disc capacity + duration
- Support multiple video formats: .mkv, .mp4, .avi, .mov, .wmv, .flv, .webm, .m4v (#12)
- Make MediaInfo fallback ratio configurable via config.json duration_minutes_per_gb (#13)

Closes #10, #12, #13

-Architecture
-------------
-The EpisodeRenamer class handles the full pipeline:
-
-1. **Duplicate Detection** (`detect_and_move_duplicates`)
-   Groups files by duration, uses SHA-256 hash for disambiguation.
-   Moves or deletes duplicates based on --force flag.
-
-2. **Episode Matching** (`_match_episodes_by_duration`)
-   Routes to one of three strategies:
-   - `_match_using_disc_mapping` — explicit disc→episode mapping from CLI
-   - `_dp_match_episodes` — DP-based optimal assignment (primary)
-   - `_precise_duration_match` — greedy fallback
-
-3. **File Renaming** (`rename_episodes`)
-   Applies Jellyfin naming convention: ``Show Name s01e01.mkv``
-
-4. **Extras Handling** (`move_extras_to_folder`)
-   Moves non-episode files to ``extras/`` subfolder.
-
-Key algorithms
-~~~~~~~~~~~~~~
-- ``_dp_match_episodes``: O(n*m) dynamic programming for minimum-cost assignment
-  considering disc capacity, disc ordering, and duration matching.
-- ``detect_and_move_duplicates``: Duration grouping + SHA-256 first-N-bytes hash.
-- ``_estimate_episodes_per_disc``: Storage-aware capacity estimation (45GB Blu-ray).
-
-Configuration
-~~~~~~~~~~~~~
-- ``disc_mapping``: Optional explicit disc→episode mapping
-- ``auto_delete_duplicates``: Only ``True`` with ``--force`` flag
-
-Safety

-- ``auto_delete_duplicates=False`` by default
-- ``--force`` required for actual file deletion
