v0.1.12 - Current workspace configuration and wider bundle review

Changes

• Bundle review uses the full content width without an unrelated live preview, with readable desktop columns and a stacked mobile layout.
• Configuration shows the current workspace's actual title, wording, colors, fonts, prompts and app-file fields, whether created manually or imported.
• App-file edits use revision checks and an explicit restart notice. Model Apply persists to the app file.
• Code helpers reopen saved drafts or existing connector source as inert text. Saving a draft never activates or runs it.
• Imported workspaces have an explicit configuration link and remain separate from the original app.
• Saved keys remain private and available only within their workspace. Portable exports exclude keys.

Verified before release

• Exact GitHub source and rebuilt wheel: 461 tests each, 459 passed and 2 optional skips.
• Browser tests: manually created workspace edit/restart/reopen; ZIP and YAML import/run; imported configuration; cited Demo answer; stop/remove; all 9 offline prompt generators and both code routes.
• Navigation, scrolling and review layout tested at 1366, 980, 760 and 390 pixels; actual screenshots inspected.
• Missing/invalid token access denied for the new configuration and helper-draft endpoints.

Model-dependent checks use Demo/test doubles, not a live model. All app-file edits require restarting the workspace to apply all fields. Python connectors run in a bounded subprocess, not a security sandbox.
