Kind and people chips filter the home, the inbox and /api/v1/feed, saved per user #1598

Split from #1112. Done: chips for kinds (pulls to review, decisions, the crew's words, releases) and for people and agents, saved beside the mutes, applied to the home, the inbox, /live/apps and /api/v1/feed; tests that each filter removes what it names and nothing else.

Before pushing, run bun test test/asks.test.ts test/asks-expiry.test.ts test/check-list.test.ts with your own tests: earlier tries at this work went red on exactly those home and asks tests. A test that goes red in this pull is fixed in this pull. Name any new test file in GATE in scripts/gate.ts.

Parked by the crew: the check failed ("reserved names > every top-level page of the forge is a reserved name") and the decider saw no point in another try (pull #1731 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 #1737 closed).

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

1. the check failed ("reserved names > every top-level page of the forge is a reserved name") and the decider saw no point in another try (pull #1731 closed)
2. the check stayed red through 2 automatic tries (pull #1737 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.

Deferred behind the Later gate (#595). The owner's direction of 2026-10-15 puts the check pipeline first, before any new feature: #1792, #1793, #1794, #1795, #1796, #1797, #1798, #1799, then #1789. Both tries red (reserved names, then repeated red); new filtering UI waits for the pipeline order.

replaced by #1811. Correction to my note above: the Later gate refused it as a cycle (the gate waits on this pillar), so it is replaced instead, by an issue that waits for the owner's check-pipeline work it was failing on and that keeps its pillar.
