fix(flashcard): name the Anki deck from #+TITLE, not the filename

flashcard-to-anki.py's default_deck_name returned the input basename, so a deck built through flashcard-sync (which passes no --deck) was named after the file slug (refutation-drill) instead of the curated #+TITLE the phone deck should read (Refutations). flashcard-review.org already documented the #+TITLE behavior, and the script never matched it. default_deck_name now scans for a #+TITLE line (case-insensitive, trimmed) and falls back to the basename when there's none.

Five new tests cover title-drives-name, trimming, case-insensitivity, and the two basename fallbacks. The two old tests that asserted basename-always are replaced. The pre-staged script and test (validated 2026-06-21) applied cleanly red-to-green; their redundant copies are removed and the rationale doc kept.

Migration: deck IDs derive from the name, so decks previously built without --deck land as new decks on the next import. Old basename-named decks keep their history and can be deleted by hand.

-"""Convert an org-drill file into an Anki .apkg deck.
-
-Parses org-drill structure:
-  - Top-level "* Section" headings become tags on every card under them.
-  - Each "** Card name :drill:" entry becomes a card. Front = heading
-    text (sans :drill: tag). Back = entry body with newlines converted
-    to <br>.
-
-Deck name defaults to the org #+TITLE: (so the phone deck reads as the
-curated title), falling back to the input basename when the source has
-no #+TITLE. Deck and model IDs are derived from the deck name via stable
-hash so re-importing the same deck updates existing cards instead of
-duplicating them.
-
-Output defaults to ~/sync/phone/anki/<input-basename>.apkg. The .apkg is
-a mobile-Anki artifact the phone picks up from its sync dir, so it lands
-there rather than next to the org source.
-
-Usage:
-  flashcard-to-anki.py <input.org>
-  flashcard-to-anki.py <input.org> --deck "My Deck Name"
-  flashcard-to-anki.py <input.org> --output /path/to/deck.apkg
-
-Requires genanki, which uv resolves automatically via the PEP 723
-script metadata above. No venv or system install needed.
