v0.2.0

v0.2.0 — paginated garden, mask + demo modes, theme-aware creature palettes

Highlights since v0.1.1:

• Paginated garden — [ / ] keys cycle pages, capacity derived from
canvas size, sidebar mirrors the current page, termcn-style
pagination strip up top.
• Mask mode (m) — fake creature aliases, redacted commit subjects,
per-vibe generic reasons, ◐ mask indicator inline in the tagline
so the toggle never shifts the viewport. 700ms letter-scramble
animation between states.
• Demo mode — secret screenshot-friendly mode with believable repo
names. Triggers: REPOGARDEN_DEMO=1 env var, or type "demo" in the
garden view.
• Identity-only creature colors + theme-aware palettes — every one
of the 39 themes ships its own creaturePalette (arcade, neon,
earthy, pastel, forest, arctic, etc.). Vibe still reads through
the colored glyph in the name strip.
• Per-root scan progress visible from the moment roots resolve.
• Footer + help overlay trimmed; jk binding removed from
garden/shelf (arrows only, j/k stay scoped to content panes).
• Usage strip silently drops error/auth provider rows.
• Sprite identity stable across the mask/demo toggle so the herd
keeps its familiar shapes and palette.
• Star (★) on the Credit link and a one-line nudge in the README.
• Dropped ink-text-input dependency.
• Fresh README preview image.
