Fixes two base reds that came in with #23391 (reported by chief-sidebar):

• ChiefWorkspaceRowsTests.theTaskTitleDropsOnlyASubagentID: ChiefWorkspaceName.taskTitle trimmed blanks on both ends before looking for the aN · id, so "a3 · " became "a3 ·", the " · " match failed, and it returned "a3 ·" instead of nil. It now drops only the leading blanks before the match; the trailing ones still go after.
• ChiefSidebarItemTests.dedupedSessionNamesKeepTheirRoleAndNumber: the test still expected the internal a3 / a10 ids as row titles. cmux-next sidebar: the Chief's workspaces read like any workspace (no aN id, no Chief line) #23391 hides those ids on purpose (Leo's ask), and an untitled lane reads "Subagent". The test now gives the lanes task titles and checks that they keep their subagent-number order.

Example failing run: https://github.com/manaflow-ai/cmux/actions/runs/39635743092/job/119347539209

No capture: a string helper and a test, with no visible change beyond the "a3 · " edge case.

Summary by cubic

Fixes two Chief title test failures that came in with #23391.

• ChiefWorkspaceName.taskTitle now drops only leading whitespace before matching the subagent id, so "a3 · " keeps its " · " marker and no longer returns "a3 ·" instead of nil.
• The deduped-session test now gives lanes task titles and checks their subagent-number order, instead of expecting the internal a3/a10 ids as row titles.

Not verified: macOS jobs did not run: compile and app tests were skipped on 8c9b0834f2; ci-status is green without them.

CI passes on 8c9b0834f2 (run 39656483087 attempt 1).
macOS jobs did not run: compile and app tests were skipped: Fast static checks skipped (the macos job needs both to succeed). Re-run CI once they pass, before merging.

Written by scripts/ci/classify_failures.py (ci-failure-attribution.yml); signatures are its SIGNATURES table. A machine verdict is the runner's fault, not this PR's; yours means the failing file is one this PR changes, also red on main that main's latest full suite fails the same way, seen on other PRs that it failed on another pull request's run lately.

red: cmux-next checks (god files, concurrency, crash safety, l10n); no finished base run on c7626f2 to compare; do not merge until green; see lane-rules
