v0.1.0

the ETL flow got fixed up, and a toolbox moved in next door.

⚠️ Breaking: CSV inputs are objects now

CSV inputs now parse to an array of objects keyed by the header row, with dynamicTyping on (numbers and booleans come through typed). they used to be string[][]. any transform that indexes row[0] needs to switch to row.<column>:

// before
return input.data.map((row) => row[0]);
// after
return input.data.map((row) => row.name);

hit Reload Types on old transforms so the TYPE DEFS block picks up the real column names.

Added

• Toolbox: 19 offline tools in a webview dashboard. Encode: Base64, URL, HTML entities, Hex, JWT. Convert: JSON Format, JSON ⇄ YAML, JSON ⇄ CSV, JSON ⇄ TOML, JSON → TS Types. Generate: UUID, Timestamp, Hash, Lorem Ipsum, Random String. Inspect: Regex Tester, JSONPath, Text Diff, Cron Explain.
• toolbox output actions: Copy, Insert, Open in Editor, and Send to Pipeline (turns the output into a session input).
• Toolbox sidebar view, grouped by category.
• launcher: JScratch: Open Tool… on Ctrl+Alt+J / Cmd+Alt+J.
• JScratch › editor context submenu with quick actions on the selection: Base64 Encode/Decode, URL Encode/Decode, Format JSON, Minify JSON, JSON → YAML, Decode JWT.
• Data preview: a sortable, filterable table for JSON, CSV and NDJSON files, with per-column types and null counts. refreshes when the file changes. opens from tree nodes, the editor title bar and a Preview Input CodeLens.
• Add Input sources: empty file, clipboard, file from disk, active editor. files dragged onto the tree become inputs.
• branching: a node can have several transforms.
• run status badges on nodes and editor tabs (ran, failed, stale), plus row counts and last run duration in the tree.
• Run Branch: runs a transform and everything downstream, stopping at the first failure.
• Set Output Format per transform: json, csv, ndjson or txt.
• Reload Types: regenerates a transform's TYPE DEFS block from its current input.
• run toasts with Show Log and Open Script on failure.
• settings: jscratch.pipeline.runOnSave, jscratch.pipeline.timeoutMs, jscratch.pipeline.defaultOutputFormat, jscratch.preview.maxRows.
• welcome views for "no session" and "empty session".

Changed

• CSV parsing (see the breaking note above).
• the pipeline renders as a real nested tree instead of a flat list.
• transforms run in a separate Node process (VS Code's own binary) with a configurable timeout. logs stream live to the JScratch output channel, prefixed with the script name.
• Add Transform always creates a new transform instead of reopening the existing one. the name prompt is prefilled with transform-N.ts.
• new outputs are named <transform>.out.<ext>. old output-<ts>.json files keep their names.
• outputs open beside the editor without stealing focus.
• the transform template notes that console.log is safe.
• every command sits under the JScratch category, and context-only commands are hidden from the palette.
• redrawn icon set: marketplace icon, activity bar icon, per-node tree icons.
• platform-specific packages for Linux, macOS and Windows (x64 + arm64), each carrying only its own esbuild binary. transforms used to fail outside Linux because only the Linux binary shipped, and the package is half the size now.
• the README's ETL example now matches the real template (export function transform(), no export default).

Fixed

• console.log in a transform no longer corrupts the output file. results go through a separate file, so stdout is just logs.
• cancelling a run works at any point, including while the script is still bundling.
• the active session persists across VS Code restarts.
