Audit and remove legacy Code Everywhere remote inbox path

[cbusillo]

Problem

cbusillo/code-everywhere has been archived/discontinued, but the active code repo still carries legacy Code Everywhere-specific names and possibly a legacy endpoint adapter inside otherwise useful remote UI/session-control infrastructure.

This should not become a broad deletion pass. The Discord bridge and the generic capabilities it depends on should stay. The goal is to separate reusable Every Code remote-control primitives from archived Code Everywhere product baggage.

Current evidence:

• code-rs/core/src/config.rs still exposes remote_inbox.code_everywhere_url alongside the current bridge_url.
• code-rs/tui/src/remote_inbox/client.rs still spawns spawn_code_everywhere_http_client(...) when code_everywhere_url is configured.
• The same client contains CodeEverywhereHttpClient, CodeEverywhereCommand, code_everywhere_* mappers, polling, snapshot, command-claim, and command-outcome code.
• Several runtime/log/user-visible strings still say Code Everywhere, including command issued_by values.
• code-rs/tui/src/chatwidget.rs has Code Everywhere smoke helper names and prompt text.
• Tests still cover the Code Everywhere HTTP path and naming.

The current Discord integration lives in the active discord-blue repo and should not be confused with the archived code-everywhere project. The surviving integration and reusable remote UI capabilities should be preserved under current Every Code / remote inbox naming.

Keep

Preserve generic features that are useful for Discord today and for future UI/DUI surfaces, including:

• remote session hello/presence/status snapshots
• timeline/status fanout
• command claim/ack/reject semantics when still useful outside the archived service
• remote reply, continue, pause, new-session, end-session, approval, and request_user_input plumbing
• host identity/label support
• tests that prove the generic remote-control protocol still works

Expected outcome

Audit the legacy Code Everywhere support and make a deliberate split:

• Keep the active Every Code remote inbox / Discord bridge behavior working.
• Keep generic remote UI/session-control primitives that could support a future UI we love or a broader DUI.
• Remove the discontinued code_everywhere_url HTTP compatibility path only if no active or planned surface still needs that exact adapter.
• Rename reusable CodeEverywhere* types/functions/tests/smoke helpers to current EveryCode, RemoteInbox, or similarly neutral names.
• Replace user-visible/log/issued-by strings that still say Code Everywhere with current Every Code or neutral remote inbox wording.
• If the legacy HTTP compatibility path should remain temporarily, document its current owner, endpoint, and retirement criteria so it is not mistaken for the archived project.

Validation

• Existing remote inbox tests pass.
• Active Discord bridge/manual control flow remains compatible.
• Generic remote-control behavior remains available for future UI/DUI expansion.
• Config docs/tests no longer advertise a discontinued code_everywhere_url path unless it is explicitly retained as temporary compatibility.

Related context

• cbusillo/code-everywhere is archived and has no open issues after discontinuation cleanup.
• discord-blue issues fix(tui/limits): refresh expired reset windows over HTTP #28 and Detached tmux Every Code sessions do not register with DUI until attach #29 track active Every Code Discord control behavior, not the archived Code Everywhere repo.

Completed in PR #23 and merged into local/cbusillo-overlay at 3e95dba.\n\nWhat changed:\n- Removed the archived Code Everywhere HTTP polling adapter from the TUI remote inbox client.\n- Kept the active Every Code / Discord WebSocket bridge path and timeline fanout.\n- Kept legacy remote_inbox.code_everywhere_url compatibility only for ws:// / wss:// bridge URLs. Legacy HTTP polling URLs now warn and are not silently treated as bridge URLs.\n- Updated repo workflow metadata away from Code Everywhere wording.\n\nValidation:\n- ./build-fast.sh\n- just local-code-rebuild\n- local DUI bridge smoke with remote_inbox.bridge_url: hello, heartbeat, command_ack, returncode 0\n- local DUI bridge smoke with legacy remote_inbox.code_everywhere_url using ws://: hello, heartbeat, command_ack, returncode 0\n- discord-blue Every Code tests: uv run python -m unittest tests.test_every_code (58 OK)\n\nRelease decision: no standalone release cut for this cleanup; the merged overlay has been rebuilt locally and can ride the next normal release.
