The home's duplicate "What you asked for" link leaves, and the Asked tab shows how many asks are still in flight #5822

Home draws an Asked tab (src/web/studio/home_tabs.ts) and, above the timeline, a separate What you asked for link (src/web/studio/home.ts). These are two doors to one page.

Done when:

• [ ] The .bar.feed-head link on / is gone. If the bar is then empty, the bar goes too, and docs/design/areas/feed.md is updated.
• [ ] The Asked tab reads Asked 3 when 3 asks have not landed yet, using the counts /asked already computes (askedCounts in src/core/asked.ts). At zero it reads plain Asked.
• [ ] The count's read is a named Server-Timing phase on / and stays under 5 ms warm.
• [ ] Tests: the link is absent, and the tab's count matches /asked for one seeded forge. Update any test that clicked the old link to use the tab, and say so in the pull.

Parked by the crew: the check stayed red through 2 automatic tries (pull #5832 closed). Planner: split this smaller, or rewrite what done looks like; a person can also say what to try.

Parked by the crew: the check stayed red through 2 automatic tries (pull #6315 closed).

Parked twice since a person last spoke here, so it is the planner's now. Every reason:

1. the check stayed red through 2 automatic tries (pull #5832 closed)
2. the check stayed red through 2 automatic tries (pull #6315 closed)

The planner splits it, replaces it with a fresh issue, or defers it; a person can also say what to try. Nothing starts here until then, and the board lists it.

Split into #6744 (the bar leaves; fresh from main, check the design doc has no conflict markers, which is what reddened #6315) and #6745 (the Asked tab count, after #6744). Closing as split.
