Keep PEP 723 inline script CodeLens live and persistent

[Stella Huang (StellaHuang95)]

Summary

• Keep the setup CodeLens available whenever a recognizable PEP 723 script block exists, including incomplete or malformed live edits.
• Keep Script environment ready (Python X.Y.Z) persistent for validated, available script environments.
• Re-evaluate unsaved metadata edits immediately while preserving Ready and exact-file routing for body-only edits.
• Prevent pending saved-metadata reads from restoring stale routing after a live metadata edit.
• Validate malformed metadata when setup is invoked, preserving diagnostics and avoiding invalid environment associations.
• Harden setup, save, cache-repair, and stale-operation behavior and document the updated user flow.
• Add focused parser, routing, CodeLens, detector, setup, manager, and real VS Code integration coverage.

Validation

• npm run lint
• npm run compile-tests
• npm run unittest — 2,812 passing, 7 pending after rebasing onto the latest main
• Production webpack build
• Inline VS Code integration — 8 passing
• Real-environment PEP 723 workflows — 21 passing
• Smoke suite — 31 passing
• Environment discovery E2E — 4 passing
• Manual Windows VS Code Insiders testbed matrix covering setup, persistent Ready, live edits, Undo/Revert, malformed metadata, diagnostics, quick fixes, Run File, Pylance routing, cache repair, restart persistence, and feature-off behavior
• Static core, additional-use-case, quick-fix, and 8-KiB boundary verification

Notes

The tolerant block detector is presentation-only. Semantic parsing remains authoritative for diagnostics, setup eligibility, environment identity, persistence, and exact-file routing.

A separate full integration run completed with 57 passing and 8 pending tests plus one existing environment-creation timeout. The timed-out fixture selects the system manager, which cannot quick-create headlessly; instrumentation confirmed it does not enter the PEP 723 path.

Result: ⚠️ partially-verified

Verification details

Verification: Isolated verification observed failures that were not classified as caused by this PR: Batched dependency and test discovery. The relevant tests could not be fully run in the isolated environment; this review is not fully verified.

Summary: Offline dependency installation and `npm run compile-tests` succeeded in the container. Targeted inline-script suites passed: 285 common, 214 feature, and 370 manager tests, with 5 manager tests pending. No executed test failed; discovery's Git probes failed because the container checkout lacked Git metadata. The eight new VS Code integration tests could not run because no downloaded VS Code runtime was available. Unit coverage supports the live CodeLens, persistent Ready, validation, and routing behavior, but editor-host verification remains incomplete.

Discovery reported .vscode-test false. These eight tests require a real VS Code extension host; downloading VS Code or extensions is unsupported in the network-isolated verification environment. Command was not executed.

Result: ⚠️ partially-verified

Verification details

Verification: The relevant tests could not be fully run in the isolated environment; this review is not fully verified.

Summary: Offline dependency installation and test compilation passed in the disposable container. Targeted inline-script suites reported **870 passing tests**, no failures, and five pending Windows-specific tests. Coverage included persistent Ready labels, live metadata edits, Undo, stale reads, setup validation, routing, and cache recovery. The eight new VS Code integration tests were not run because the sandbox lacks the required Electron/extension-host environment. Confidence is strong for unit-tested behavior, but end-to-end editor behavior remains unverified.
