feat(skills): consolidate 30 skills into single zerion skill + fix init.js

Onboarding pain: 30 separate skills polluted agentskills.io picker and
scattered install counts. Now one `zerion` skill at the top, with
progressive disclosure via nested `capabilities/*.md` (core: analyze,
trading, sign, wallet, agent-management, swap-0x) and `partners/*.md`
(Bankr, Li.Fi, Moonpay, Vaults.fyi, Trails, etc.). Same total content,
loaded on demand — root SKILL.md stays ~150 lines.

init.js fixes:
- ensureGlobalInstall now short-circuits if `zerion --version` already
  resolves globally, even when npx temp dir hosts the binary (was
  re-installing on every run when CLI was already present).
- installSkills auto-detects the user's coding agent (env fingerprints
  + ~/.<agent> dirs for claude-code, cursor, codex, gemini) and passes
  `-a <agent>` to `npx skills add` so the 55-agent multi-select picker
  doesn't open. ~70% of users are on Claude Code — this skips the
  manual checkbox dance evgen flagged.

-The agent reaches for the right skill (e.g. `zerion-analyze` for "what's in this wallet", `zerion-trading` for swap/bridge/send) and invokes the underlying `zerion` CLI commands. Skills load only when relevant — agentskills.io's progressive disclosure keeps your context window clean. Multiple skills compose at runtime: a "create wallet, set up agent token, then swap" flow loads `zerion-wallet` → `zerion-agent-management` → `zerion-trading` in sequence.
+The agent reaches for the `zerion` skill, which routes by task to the right nested file under `capabilities/` or `partners/`. Progressive disclosure means only the matching capability doc loads — context stays clean. A "create wallet, set up agent token, then swap" flow Reads `capabilities/wallet.md` → `capabilities/agent-management.md` → `capabilities/trading.md` in sequence.
 
 ## Manual setup, agent execution
 
 Zerion CLI splits into two surfaces, by design.
 
-- **Wallet management and agent token setup are manual.** `wallet create`, `import`, `backup`, and `delete` all prompt for a passphrase. `wallet sync` emits a QR code you scan with the Zerion app. `agent create-token` mints a scoped trading credential bound to a specific wallet, and `agent create-policy` attaches the rules it has to obey — allowed chains, expiry, transfer/approval gates, contract allowlists. The sibling admin commands (`agent list-tokens`, `use-token`, `revoke-token`, `list-policies`, `show-policy`, `delete-policy`) are also gestures you make yourself. No key material moves and no spending credential widens without you in the loop. For CI and headless servers, `agent create-token` accepts `--passphrase-file <path>` (file must be mode `0600`) so token issuance can be scripted without an interactive TTY — see the `zerion-agent-management` skill.

 - **Analysis, signing, trading, and discovery are for agents.** `analyze`, `portfolio`, `positions`, `history`, `pnl`, `sign-message`, `sign-typed-data`, `swap`, `bridge`, `send`, `swap tokens`, `search`, `chains`, `wallet list`, `wallet fund`, and `watch list` emit JSON to stdout, structured errors to stderr, and skip confirmation dialogs. Once an agent token is configured, signing and trading fire immediately — the token authorizes operations on behalf of the wallet without a passphrase prompt.
 
 Setup gestures (`init`, `setup skills`, `config set/unset/list`, `watch` add/remove) are one-time configuration steps you run yourself before automation takes over.
