Summary

• Fixes an unbounded growth of context.subscriptions: every launch pushed its shell-integration listener, its fallback timer, and its shell-execution listener onto the extension subscription list, which VS Code only drains on deactivation. Each launch now owns a disposal scope (createLaunchSession) that ends when the command finishes, when the sendText fallback runs, or when its terminal closes. deactivate drains whatever is left, and only activate registers on context.subscriptions.
• Fixes a leaked onDidEndTerminalShellExecution listener: it was never disposed when a terminal closed before its command finished, so it stayed live for the rest of the session.
• Stops reading terminal shell output for custom CLI commands. Output was buffered on every launch even though only the Codex missing-CLI check consumes it, which did not match the trust boundary documented in docs/architecture.md or the 0.1.8 changelog entry.
• Removes the unused scripts/generate-icon.js placeholder generator and its generate:icon script. Nothing referenced it, and running it overwrote the published media/icon.png (23,173 bytes, hand-authored) with a different 1,955-byte placeholder. Verified by running the script against a scratch directory and comparing hashes; the published artwork is untouched by this PR.
• Releases 0.1.9 and rewrites AGENTS.md with the stack, real commands, launch lifecycle, protected assets, compatibility rules, and validation criteria.

No behavior visible to users changes: the same terminal is created, the same command is sent, and the missing-Codex documentation prompt still fires on the same conditions.

Validation

• npm run check — 39 unit tests pass, VS Code 1.103.0 integration smoke test exits 0, vsce ls lists 12 files
• npm run audit — 0 vulnerabilities
• Packaged VSIX inspected — vscode-codex-cli-launcher-0.1.9.vsix, 14 entries, 63.25 KB; no sources, tests, AGENTS.md, workflows, lockfile, or source maps
• Installed the VSIX into an isolated --extensions-dir / --user-data-dir profile; --list-extensions --show-versions reports mikesoft.vscode-codex-cli-launcher@0.1.9

Checklist

• Tests cover new or changed behavior — 4 unit tests for the disposal scope plus 3 source-level lifecycle invariants in test/extension-lifecycle.test.js
• User-facing behavior is documented — no user-facing behavior changed; docs/architecture.md gains a launch lifecycle section
• CHANGELOG.md is updated
• Workspace trust, command scope, telemetry, and installer restrictions remain intact
• No generated files, secrets, or unrelated changes are included

Screenshots or Notes

No UI change, so no screenshots apply.

Known issues left untouched:

• media/launcher-mark.svg is 51.7 KB and embeds two base64 PNGs at 256 px, which is 82% of the VSIX payload for an icon that renders at toolbar size. Not changed here because it is published artwork; worth a separate design pass.
• The repository has no GitHub Actions secret and no local VSCE_PAT / OVSX_PAT, so publishing to the Marketplace and Open VSX remains a manual maintainer step after this merges.
