Overhaul bottom bar: batch add, custom fields, stat block viewer

Unify the action bar into a single search input with inline bestiary
dropdown. Clicking a dropdown entry queues it with +/- count controls
and a confirm button; Enter or confirm adds N copies to combat.

When no bestiary match exists, optional Init/AC/MaxHP fields appear
for custom creatures. The eye icon opens a separate search dropdown
to preview stat blocks without leaving the add flow.

Fix batch-add bug where only the last creature got a creatureId by
using store.save() instead of setEncounter() in addFromBestiary.
Prevent dropdown buttons from stealing input focus so Enter confirms
the queued batch.

Remove the now-redundant BestiarySearch component.

+# Implementation Plan: Bottom Bar Overhaul
+
+**Branch**: `036-bottombar-overhaul` | **Date**: 2026-03-11 | **Spec**: [spec.md](./spec.md)
+**Input**: Feature specification from `/specs/036-bottombar-overhaul/spec.md`
+
+## Summary
+
+Overhaul the bottom bar action bar to support batch-adding predefined creatures (click-to-queue with count + confirm), optional stat fields for custom creatures (initiative, AC, max HP), stat block preview from the search dropdown, and improved placeholder text. All changes are in the adapter (web) layer — no domain or application changes needed. The existing `addFromBestiary` hook method is called N times in a loop for batch adds.
+
+## Technical Context
+
+**Language/Version**: TypeScript 5.8 (strict mode, `verbatimModuleSyntax`)
+**Primary Dependencies**: React 19, Tailwind CSS v4, Lucide React (icons)
+**Storage**: N/A (no persistence changes — queue state and custom fields are ephemeral)
+**Testing**: Vitest (unit tests for any extracted logic)
+**Target Platform**: Web (desktop + mobile responsive)
+**Project Type**: Web application (monorepo: apps/web, packages/domain, packages/application)
+**Performance Goals**: Instant UI response for queue interactions
+**Constraints**: Local-first, single-user, offline-capable
+**Scale/Scope**: Single encounter screen, bottom bar component
+
+## Constitution Check
+
+*GATE: Must pass before Phase 0 research. Re-check after Phase 1 design.*
+
+| Principle | Status | Notes |
+|-----------|--------|-------|
+| I. Deterministic Domain Core | PASS | No domain changes. Queue state is UI-only. |
+| II. Layered Architecture | PASS | All changes in adapter layer (apps/web). Calls existing domain/application functions. |
+| III. Clarification-First | PASS | No non-trivial assumptions — spec is detailed. |
+| IV. Escalation Gates | PASS | Implementation stays within spec scope. |
+| V. MVP Baseline Language | PASS | No permanent bans introduced. |
+| VI. No Gameplay Rules | PASS | No gameplay mechanics in plan. |

+
+**Structure Decision**: All changes are within `apps/web/src/components/` (adapter layer). The action bar component is the primary modification target. The existing `BestiarySearch` component's dropdown functionality will be integrated directly into the action bar's unified search flow. No new packages or layers needed.
