feat: one-command onboarding — wanderbooks new, install.sh, justfile

wanderbooks new DIR installs the server and GUI if missing, writes the
books dir (AGENTS.md + CLAUDE.md, wanderbooks.toml, justfile, .mcp.json,
.claude/settings.json approving the server), commits, and starts claude
onboarding. install.sh: Rust + cargo install + wanderbooks new in one
line. The tax summary labels its net when accounts are uncategorized.

+anything. Keep it conversational; ask a few things at a time.
 
-1. Ask: company legal name, entity type, owners and equity split, base
-   currency, fiscal year start.
-2. Set up the chart of accounts: propose a sensible default for the entity
-   type and let the human adjust, or import one they hand you.
-3. Record opening balances as one balanced opening entry. Verify the trial
-   balance balances before moving on.
-4. Write the answers into `wanderbooks.toml` under `[company]`.
-5. If they're migrating from another system, import from wherever the books
-   live now — QBO/CSV via `ledger-import`, bank or card CSVs, email receipts,
-   a spreadsheet, whatever they point you at. Diff trial balance, P&L,

+1. Ask: company legal name, entity type (sole proprietorship or
+   single-member LLC, partnership or multi-member LLC, S corp, C corp),
+   owners and their shares, fiscal year start, and whether they want
+   accrual or cash basis.
+2. Propose a chart of accounts with `books.chart_template` for that entity
+   type and those owners. Walk the human through it, adjust, then import it
+   with `books.import_chart_csv`. Put the template's settings (members,
+   tax form, close target) in `wanderbooks.toml`.
+3. Fill in `wanderbooks.toml` `[company]`: name, entity type, tax
+   classification, formation state and date, EIN, address. Don't store
+   SSNs or full account numbers anywhere in this directory.
+4. Record opening balances as one balanced opening entry (or the owners'
+   first contributions). Verify the trial balance before moving on.
+5. File the formation documents they have (articles, EIN letter,
+   operating agreement) with `books.file_document`.

 - `books.digest` is the review surface — "what did you do with my books

 - Reports are pure functions of the journal. If a number looks wrong, the
   journal is the evidence — read it, don't guess.
