feat(02-04): ink compilation pipeline + 4 authored Season-1 Ink files + runtime loader

- scripts/compile-ink.mjs: build-time inklecate runner using bundled binary
  (BLOCKER 4 — uses node_modules/inklecate/bin, not stale -windows/-mac path strings).
  Assumption A6 verified first-try on Windows; the same binary path resolution
  works on macOS + Linux per the wrapper's own getInklecatePath convention.
- scripts/compile-ink.test.mjs: 3 Vitest cases proving the compiler runs +
  emits valid JSON with inkVersion. wipe=false for the test path so it can
  run in parallel with the ink-loader test without racing on the wipe step.
- 4 Season-1 .ink files authored in voice (Lura warmth-anchor, gardener-keeper
  for compost): lura-arrival.ink, lura-mid.ink, lura-farewell.ink,
  compost-acknowledgements.ink (rewrite of Plan 02-03 scaffolded version into
  VAR-driven branch shape consumable by the runtime).
- src/content/ink-loader.ts: loadInkStory + bindGardenStateToInk +
  INK_VARIABLE_MAP. Centralized snake_case slot mapping per Pitfall 4. UTF-8
  BOM stripped before Story instantiation.
- src/content/ink-loader.test.ts: 8 cases — Story instantiation for all 4
  beats, fragment_count binding, Pitfall 4 snake_case enforcement, silent
  skip for stories missing declared vars.
- package.json: build now runs compile:ink first; ci chain runs compile:ink
  before test so ink-loader.test.ts's precondition check passes.
- .gitignore: src/content/compiled-ink/ excluded (regenerated on every build).

npm run ci exits 0; 11 new tests green (228 total).

 //
-// Plan 02-03 ships the AUTHORED CONTENT for the compost tonal beat
-// (CONTEXT D-07 + GARD-04). Plan 02-04 owns the Ink runtime — this file
-// is loaded by the Ink runtime (inkjs) at that point and one of these
-// short lines is dripped into the dialogue overlay each time the player
-// composts an immature plant.
+// Phase 2 NOTE — UI WIRING DEFERRED TO PLAN 02-05:
+// Plan 02-04 ships the Ink compile pipeline + runtime + LuraDialogue
+// overlay. The compost-beat surface is a thinner toast variant (separate
+// from the Lura full-screen overlay) and is folded into Plan 02-05's
+// persistence-toast UI surface for minimum-viable-bias reasons documented
+// in 02-04-SUMMARY.md.
 //
-// In Plan 02-03 the React surface (Garden.ts handleTilePointerDown's
-// compost branch) does NOT yet render these lines — there's a TODO
-// comment at the call site marking the Plan 02-04 wiring point. The
-// content lives here so the writer can iterate on voice without waiting
-// for the runtime to land.
+// This file is rewritten in VAR-driven branch form (replacing Plan 02-03's
+// choice-list shape) so it matches the runtime contract: one ChoosePathString
+// → drip lines → END. The branching uses fragment_count to vary the line
+// without requiring the runtime to expose Ink choice points.

-// Tone (CLAUDE.md): warm, specific, intermittent, sometimes funny,
-// sometimes devastating. The gardener-keeper voice. NOT Lura. The garden
-// is acknowledging the player's choice to let go — never sentimental,
-// never reassuring, never "it's okay." Just the small fact of the choice,
-// honored.
-//
-// Phase 2 ships ~6 short lines so the player rarely hears the same line
-// twice in a single session. Plan 02-04 will randomize selection (via
-// the same mulberry32 pattern as the fragment selector, or a simple
-// weighted pick — implementer's choice).
