feat(fase-19): emoji catalog data module + EC unit tests

Hardcoded `EMOJI_CATALOG: Record<EmojiCategory, readonly string[]>` with
four categories (faces 64 / food 119 / animals 140 / objects 36 = 359
codepoints). Unicode 14 baseline, no ZWJ sequences, no skin-tone
variants so every glyph renders consistently on iOS ≥ 16 + Android.

Covers EC-U-01..04 from the plan: size lower bounds on food + animals,
no intra-category duplicates, no cross-category overlap (the picker
draws one tab at a time so a duplicate would render only in the first
tab silently and confuse the "selected" state on tab switch).

+/**
+ * Fase 19.4.2 — EmojiCatalog data-module unit tests.
+ *
+ * The catalog is a hardcoded `Record<EmojiCategory, readonly string[]>`. It
+ * has to satisfy size lower bounds (food + animals are the headline categories
+ * being expanded), and never let a single emoji land in two categories — the
+ * picker draws one tab at a time so duplicates would render in only one tab
+ * silently and confuse the "selected" highlight when the source-of-truth tab
+ * changes.
+ *
+ * Specs:
+ *   EC-U-01 — food >= 85 entries.
+ *   EC-U-02 — animals >= 130 entries.
+ *   EC-U-03 — no duplicates within any category.
+ *   EC-U-04 — no overlap across categories (an emoji belongs to exactly one).

+/**
+ * Fase 19.1 — Emoji catalogue.
+ *
+ * Source of truth for the avatar / collective-icon picker. Hardcoded — not
+ * fetched — because the list grows once per Unicode release and is small
+ * enough (~280 strings, ~3KB) to ship in the JS bundle.
+ *
+ * Inclusion rules (kept narrow so every codepoint renders consistently on
+ * iOS Safari ≥ 16, Android Chrome, and desktop browsers):
+ *
+ *   1. Unicode 14 baseline only. Unicode 15 + 16 codepoints (🩷, 🩵, 🪿,
+ *      🪿, 🫨 etc.) are excluded — iOS < 17 renders them as tofu.
+ *   2. NO ZWJ sequences (no 👨‍👩‍👧, no 🐕‍🦺, no 🏳️‍🌈). Two reasons:
+ *      (a) the picker stores `users.avatar_emoji` as text and ZWJ
+ *      sequences serialize as multi-codepoint strings whose width is
+ *      font-dependent; (b) older Android skins render them as the
+ *      component glyphs side-by-side.
+ *   3. NO skin-tone variants (🏻 .. 🏿). Parked for a future pass — the
+ *      base codepoint always renders and is good enough for an avatar.
+ *   4. Variation selectors kept where the canonical emoji form needs
+ *      them (☀️ U+2600 U+FE0F, ❤️ U+2764 U+FE0F) — leaving them off
+ *      shows the text presentation.
+ *
+ * Total ~280 entries split across four categories. The catalog must satisfy
+ * the invariants enforced by `emoji-catalog.test.ts` (size lower bounds,
+ * no intra-category duplicates, no cross-category overlap).
+ *
+ * Mutation procedure when Unicode lifts the floor: edit this file by hand,
+ * run `pnpm --filter @colectivo/web test:unit -- emoji-catalog`, and verify
+ * the bundle-size delta stays under ~10 KB gzipped.
