Regression: non-file feed operations collapse to opaque Ran ellipsis rows

[Juliusolsson05]

Regression

The post-ledger feed rewrite makes non-file operations close to unusable in real sessions.

Observed in the July 14 npm start build:

• file writes and file edits are useful and should be preserved;
• command operations frequently render only Ran plus an opaque dark … token;
• the actual command is not visible;
• streaming/final command output is not visible as the primary content;
• surrounding non-file operation families are over-collapsed and harder to scan than the old feed.

The placeholder is consistent with commandFromLive() falling back to command: '…' while CommandCard treats that fallback as the command headline. The result is technically a rendered operation but not useful information.

User contract

For commands, the feed must show immediately:

1. the best currently known command or structured operation name;
2. live output as it arrives;
3. final output, exit status, and useful structure without requiring a mystery disclosure click;
4. an honest preparing state when the command has not been decoded yet—not Ran ….

File edit/write rendering is explicitly out of scope for rollback because it is the part of the rewrite that currently works well.

Acceptance criteria

• A live Claude Bash command shows its command text before completion.
• A live Codex exec_command shows its decoded cmd before completion.
• A partial Codex unified-exec script shows a named preparing/running row until command decoding is possible; it never claims Ran ….
• stdout/stderr streams visibly into the row before the durable result exists.
• completed commands retain the command and raw output.
• unknown/non-file operations expose useful name, parameters, status, and result by default.
• Add renderer fixtures/tests for the exact black-square ellipsis regression.
