CLI: port webview marketplace features for full parity

[mega123-art]

Summary

• Closes Port mobile marketplace features to CLI surface (full parity: 16 render + 4 form gaps) #93. The vscode surface already loads the webview (full parity, no work needed); the CLI's Ink marketplace was the only gap — it fetched agent/skill data via marketplaceEnv but rendered a fraction of it.
• Split the render layer into surfaces/cli/src/views/market/ (tiers.ts, ScrollView.tsx, AgentProfileView.tsx, SkillDetailView.tsx, PublishProgressView.tsx, HeliusPanel.tsx) and widened SkillMarket.tsx's MarketApi type to match what marketplaceEnv actually returns.
• Added: agent tier badge+gauge+ladder, earned SOL, verified GitHub repos (with "show all"), blog carousel, full comment stacks (skill + agent), required-skills checkmarks+prices+collect-all, full SKILL.md via an in-view scroll viewport (no more 1200-char truncation), dispose/re-equip, firing pulse on buy/re-equip, hide-owned filter, agent wallet search, Helius RPC status badge + settings, live 3-phase publish progress, publish image field, self blog composer.
• No webview / vscode / core changes. marketplaceEnv already exposed every method/field needed; the CLI's local MarketApi interface was just narrower than the real object it receives.
• Dropped two items from the issue's gap table after checking the actual protocol/webview source: postNote (skill comments) and publishSkill never had image/githubLink params in the wire protocol, and the webview itself doesn't expose them either — so there was nothing to port.

Test plan

• tsc --noEmit on surfaces/cli — clean
• pnpm build (tsup) in surfaces/cli — succeeds
• Confirmed via git stash diff-test that no pre-existing behavior regressed outside this branch's changes
• Manual interactive walkthrough in a real terminal with a funded devnet wallet (not possible in this sandbox — no TTY/wallet available)
