Fixes #747

What changed

• Worker chip: no dot. It shows the mark of its model family (Claude, OpenAI, DeepSeek; D285), the size of the PR chip's Octicon (0.9 of ts text), tinted by WorkerInk (needs you ink-100, working ink-88, else ink-30). Another program: no icon. The family travels in the chip address (contr-chip:worker.claude/...); WorkerChip takes the profile's model, which chatChips gets from deps.ModelOf, as the notes do. No file reads.
• Chip and link text: the markdown Link color is now ink-88 (the text's ink). The pre-pass wraps chip text and the text of Markdown links ([text](url)) in <u>, so all links in an answer are ink with an underline. Icons keep their state color.
• Docs: docs/spec/ChatView.md (Claude's text, Chips), D292; D275, D285, D286, D288 marked.

Deviations

• The underline is in the text's ink (ink-88), not a lower step: MyGo's markdown has no decoration color for links (ui.Span.DecorationColor is not reachable from markdown.Theme). A lower step needs a MyGo change.
• Bare URLs (https://…, <https://…>) get no resting underline: tags around them end the autolink. They are ink and underline on hover (MyGo's link).
• Hover keeps MyGo's link hover (pointer and its underline); the underline does not rise to ink-100.
• The mark in a chip does not hop while the worker works (an inline object, drawn once per frame of text).

Tests

• go test ./internal/app/chatview ./internal/app; scripts/check.sh: ok.
• Sheet: scripts/sheet.sh ChatViewChips, both themes checked.
• No e2e test covers chat chips.

Pre-check

1. Tests, each seen failing with the change undone: TestLinksAreUnderlined (Labels off), TestChipTextRewritesOnlyKnownNames (<u> off), TestChipIcon (worker mark off), TestWorkerChipFamily (family off; family not in dest), TestLinksHaveTheLinkColor (content-link back), TestChatChipsKnowWorkersByName (profile model off).
2. Plan: steps 1–3 done; deviations above.
3. Contract: no contract section; D292 as asked.
4. Up to date with main. Open PR Terminal: no "not running" line over the grid (#745, D290) #748 adds D290 to DECISIONS.md: a small conflict at the end of the table is likely.
5. Diff read: no leftovers.
6. Issue lines: all done; bare URLs underline on hover only.
7. Duties: the worker dot in chips is removed on purpose; ChipColor and chipDot stay for the board's worker rows.
8. Sheets made after the last code change.
