Add falconry kebbit hunting

[HarleyGilpin]

Builds on #1239 and #1240 (only the last commit is new).

Adds Piscatoris falconry:

• Matthias (5092): Talk-to dialogue or the quick Falconry option lends a gyr falcon for 500 coins — requires Hunter 43 and both hand slots free. The falconer's gloves (10024 falcon / 10023 empty) go straight into the weapon slot; they can't be equipped manually, removed by hand, or have another weapon/shield equipped over them, and walking out of the falconry area hands the bird back automatically (a new piscatoris_falconry_area area).
• Catching: Catch on spotted (43) / dark (57) / dashing (69) kebbits launches the falcon as a projectile from range. On success the kebbit is replaced by an owned caught Gyr Falcon npc (5094-5096, 60s revert to your glove if ignored); Retrieve gives the fur + bones and 104/132/156 xp. New [falconry] table holds the rows.
• Caught-falcon npc defs and options match the 634 cache; the projectile reuses the existing gyr_falcon gfx (927) — later-revision references disagree on the exact projectile id (918/922/927) so this could use an in-game look.
• The existing falconry_area_stile climb-over already handles the entrance.

Tests

FalconryTest: borrow (and level/coin rejections), catch + retrieve with xp, failed catch returns the falcon, leaving the area strips the glove.
