Part of HQ#1920, HQ#5226, HQ#5266. Follow-up to #27899.

Leo, 2026-10-30, verbatim: "that visibility into [one agent host's] guys was (and is?) pretty bad i feel like we can make more improvements to acpmux/cmux-next".

What changes

#27899 gave each runaway-session warning an action. Two of those actions name lane-place rotate:

• no autocompact cap: lane-place rotate NAME --harness claude-sr2;
• a large context: lane-place rotate NAME.

Until that command landed, they carried pending: "leo-workspace#1617", and the tooltip and acpmux ls --wide said so. It has now landed, --harness PROFILE included (merge 2248b46dc6e). This PR:

• sets pending to null for both rotate actions (hub/usage_warnings.rs, dropping ROTATE_PENDING);
• drops "leo-workspace#1617" from the tooltip text, ls --wide, the README, the schema text and the Debug lane fixture's canned lines.

Commands are unchanged. Without --yes, lane-place rotate is a dry run that shows the plan, which is the right form to copy from a tooltip. The pending field stays in the schema, for the next command that has not landed yet.

Tests

• hub/usage_warnings_tests.rs: the expected objects now have pending: null and the text without the PR number. That covers the runaway case and a peer row.
• cli/ls_table_tests.rs: the expected --wide WARN cell, no-cap: lane-place rotate big --harness claude-sr2; ctx 955k: acpmux send big /compact | lane-place rotate big; 90 sub/h: acpmux session cancel big.

Observed / Not run

• Observed: rustfmt --check is clean, and scripts/cmux-next/prepush-gate.py reports no new violations.
• Not run yet: the Rust tests and clippy on CI (cmux-ci test once the PR is open). No Swift build: the Swift change is two string constants in the Debug-only lane fixture.

No capture: copy only. The tooltip of the warning badge, captured in #27899, loses the trailing ", leo-workspace#1617" from its two rotate commands. Nothing else in the drawing changes.

Summary by cubic

Removes the leo-workspace#1617 pending mark from usage-warning actions now that lane-place rotate has landed, so tooltips and acpmux ls --wide no longer label the commands as unavailable.

• Sets pending to null for both rotate actions in hub/usage_warnings.rs.
• Drops the issue reference from tooltip text, README, schema docs, ls --wide output, and the Debug lane fixture.
• No command behavior changes.

Review (codex gpt-6.1-sol high, review-router): SHIP at dc4b937

No findings. Both rotate actions now emit pending: null, and said() / with_command() drop the suffix. The expected strings in usage_warnings_tests.rs and ls_table_tests.rs match what the code now produces. No ROTATE_PENDING or leo-workspace#1617 is left. The schema JSON parses.

cmux-ci at dc4b937 (run 41148954786): cargo clippy -p acpmux --all-targets --locked -- -D warnings is clean, and cargo test -p acpmux --lib -- usage_warn ls_table protocol_ir_is_current a_cell_without remote_summary passes 27/27.
