Closes #57.

Jenny's boss fight in the Rusty Creek clearing. Beating her emits boss-defeated, which starts the ending already on main (#138). With this PR the slice runs from start to finish: title → garden → crash → creek → Jenny's ram → maze → coffee machine → Jenny → ending.

Rules (docs/05)

Health and phases	30 hits; phases change at 20 and 10
Armour	Her nose is armoured: chair hits land from behind or while she's stunned. A hit on the nose clanks and does nothing
Damage	The charge does 2 cells, a revving Jenny 1 on contact, and each part 1
Phase 2	She charges twice, turning at the wall, and the last part rolls along the floor like a loose wheel
Phase 3	Shorter stun (2 s) and 5 parts
Dying	Resets the fight: the wall opens and the boss bar hides. Once beaten, she stays beaten

Data, not code (#156)

• Arena: read from collision. The boss-gate box's right edge is the left wall, and the floor line under the jenny spawn ends at the right wall. When Rebuild Region 1 (Rusty Creek) from the art direction #157 rebuilds Region 1, the fight follows the new art with no code change.
• Clip lengths: from boss-jenny.anims.json and boss-jenny-2.anims.json.
• Hit box: 250 × 70 px, the car body without the rear wing, inside the ~290 × 134 px sprite (measured on rev-00). It's lower than the hero's 96 px jump, so a charge can be jumped as docs/05 asks.

Checked in the browser (?region=rusty-creek&state=anomaly&boss-test)

Arena read from the data	the left wall 5446, the right wall 6010 and the floor 565
Losing	rev → charge (the hero takes 2) → crash → stunned → rev → charge → hero dead → the fight resets, the wall opens, the boss bar hides
Winning	boss bar "Jenny 30/30" → 30 hits while stunned → stall → gone → boss-defeated → stage frozen, Ending plays (absorb → glitch → "To be continued.")

In my run, the screenshot of the ending shows the ending's tears, the 404 void and the THD.exe "To be continued." window over the clearing.

Checks: typecheck passes, 141 game tests pass (7 new in enemies/jenny.test.ts), the build passes, and check_docs.py passes. docs/05 has a new "In the game" paragraph.

How to test

npm --prefix game run dev

Open http://127.0.0.1:5173/?region=rusty-creek&state=anomaly&boss-test, then Start, walk right through the gate, and:

• jump her charge (Space or K)
• hit her from behind or while she's stunned (J)

Dev builds also expose window.game for console checks (the same line as on #154).

Known

• Narrow arena. The current boss clearing is 564 px between the walls, and her box is 250 px wide, so there's little room to get behind her. This is the outdated prototype map (Rebuild Region 1 (Rusty Creek) from the art direction #157). The fight takes its walls from the data, so the rebuilt arena will fix the spacing.
• Feel still to tune: speeds of 520, 600 and 680 px/s per phase, and the part arcs. That belongs to Rework movement and combat feel against the art #156 and the 07:00 playtest.
