Feat/tui browse (#1266)

* Add interactive TUI browser command using Bubbletea v2

Adds `awesome-docker browse` to interactively explore the curated list
in a terminal UI with a category tree (left panel) and detailed resource
view (right panel). Enriches health_cache.yaml with category and
description fields so the cache is self-contained for the TUI.

* Add TUI pagination, scrolloff, and fix visual overflow

Add pagination keybindings (Ctrl+D/PgDn, Ctrl+U/PgUp, g/Home, G/End)
to both tree and list panels. Implement scrolloff (4 lines) to keep
context visible around the cursor. Fix list panel overflow caused by
Unicode characters (★, ⑂) rendering wider than lipgloss measures,
which pushed the footer off-screen. Improve selection highlight
visibility with background colors.
