feat(ui): package fingerprint visualization across config surfaces

[fullstackjam]

Summary

Follows the updated OpenBoot Redesign design file (v2): the flat "DNA segment bar" is replaced everywhere by an animated package fingerprint — tall vertical bars colored by package type (cli = green, cask = amber, npm = blue), with heights seeded deterministically per config so a given config renders the same shape on every page, rising on mount via a shared ob-rise keyframe.

New shared pieces

• src/lib/fingerprint.ts — countPackageTypes + buildFingerprint (seeded LCG for stable per-config heights)
• src/lib/components/PackageFingerprint.svelte — renders the bars + defines the global ob-rise keyframe

Applied to the four surfaces the design touches

• explore — header restyled to a "community registry / N public" pill badge with a larger title and new copy; each card gains a fingerprint
• profile — each card gains a fingerprint (matches the same config's explore fingerprint)
• dashboard (ConfigRow) — flat DNA bar → fingerprint (hidden for 0-package configs)
• config detail (ConfigDetail) — hero reworked into a bordered card with the fingerprint as a faded background, meta count-swatches, and an install-rail glow

Deliberate deviations from the static mock (it's a live, data-driven app)

• Fingerprints reflect real package counts, not the mock's hardcoded demo numbers (28/14/6)
• Unified the design's two bar-height algorithms into one seeded generator
• Rail glow uses a CSS ::before instead of two extra wrapper divs (identical look)
• Existing product features the mock omits are preserved (detail Share button, extra package sections, loading/empty states, functional sort select)

Test plan

• npm run validate passes (lint + type-check + tests + build); svelte-check 0 errors
• Verified explore, config detail, dashboard, profile in light + dark via Playwright — fingerprints render and are consistent per config across pages
• 0-package configs correctly omit the fingerprint
• Surgical diff — 4 modified + 2 new files, no repo-wide reformatting
