Move looking out of pardes.zig into look.zig

Pure move, no behaviour change (acme keeps this in look.c): expanding the
word under a click (ExpandedWord, expandedWord, expandedSel, cursorWordSel),
the n/N walk (LookFrom, lookEdge, lookStand, lookWalkPanes, lookPast,
wholeRowSpan, lookSpanIn, lookWalk, landLookSpot, noteLookSource,
armLookWalk), search results (Search, SearchStart, submitSearch,
lookFirstHit, runSearch, searchStep, jumpResult), the look-hover preview
(LookHoverWait, LookHoverPreview, FileWordSpan, PdfWordPreview,
invalidateLookHover, cancelLookHover, lookHoverPane, noteLookHover,
refreshLookHoverFromRaw, advanceLookHover) and lookAt with its targets
(focusPaneLine, selectSpan, openPaneTarget, focusPaneByPath,
clearNavigationSelection, resolveLookTarget, locationText,
canonicalLookLocation, pdfLinkLocation, followPdfLink), with five tests, go
verbatim to the end of look.zig after its word and target resolution.

The methods become free functions taking `p: *Pardes`; their 143 call sites
change from `p.lookAt(..)` to `look.lookAt(p, ..)` (tests reach them as
`pardes.look.x`). Inside look.zig the moved code's `look.` prefix drops.
