feat: add rename-ai-artifact tool and rename the drill-deck family to flashcard

Renaming an .ai artifact by hand is the kind of mechanical job that gets done incompletely: the canonical copy moves but the mirror doesn't, a reference in the INDEX is missed, a trigger phrase points at the old name. I'd also assumed a rename was costly because references scatter, when the index update is trivial and the drift check already guards it. So I built the discipline into a script instead of re-deriving it each time.

scripts/rename-ai-artifact.sh takes old and new basenames, moves the file in both the canonical and mirror trees, and rewrites every reference repo-wide on a token boundary so renaming "foo" can't corrupt "foobar" or "foo-bar". It rewrites the underscore module-name variant too (a hyphenated script imported as foo_bar via importlib), leaves the archived session records under sessions/ alone because they're history, and runs workflow-integrity + sync-check at the end to prove no drift. rename-artifact.org documents it and indexes the triggers.

Then I used the tool to do the rename that prompted it: the org-drill deck workflow and its helpers are now flashcard-named, since "flashcard" is the word you'd actually search for. The renamed set is flashcard-review.org plus flashcard-stats.py, flashcard-sync, flashcard-to-anki.py, and flashcard-diff-ids.py, with their tests, every reference, and the INDEX entry updated. The deck is still an org-drill deck under the hood, so the ":drill:" tag handling and the "drill deck" trigger phrases stay. I added "review/update the flashcards" alongside them.

Tests: 9 bats for the rename tool (including the prefix-collision and history-preservation edges), and the renamed script suites all pass under make test.

-"""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 input basename, case preserved. 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:
-  drill-to-anki.py <input.org>
-  drill-to-anki.py <input.org> --deck "My Deck Name"
-  drill-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.
