fix(terminal): stitch a wrapped line through the indent its continuation carries

An agent's numbered list wraps its URL, and the link opened a PREFIX of it:

    1. https://github.com/users/someone/packages/container/p
       ackage/thing

opened `…/container/p`. The provider already stitched hard wraps — Ink emits a real
newline, so nothing is flagged `isWrapped` and a row that fills the last column is
taken as continuing — but it joined the row texts VERBATIM, and the continuation
carries the list's own three-space indent. That whitespace lands in the middle of
the token, which is exactly where the URL pattern stops. Flush-left wrapped URLs
(Claude Code's own `/login`) worked, which is why this survived.

The touch-selection helpers had the shallower version of the same bug: they walked
`isWrapped` only, so `Line` grabbed the single row on screen rather than the
logical line, and a long-press on a wrapped token selected only its visible half.

So the reconstruction now lives in ONE place, `terminalLogicalLine` in
constants.js, and both consumers use it — the link provider matching patterns over
its text and the selection helpers measuring words and lines with it. A link that
spans a wrap and a `Line` that stops at the screen edge were the same bug twice.

The helper drops the leading whitespace of a HARD continuation (the program's
indent) and keeps that of a SOFT one (the emulator inserts nothing, so it is real
content), records the dropped width per segment so the offset↔cell mapping stays
exact in both directions, trims only the final row so earlier offsets stay aligned
to cells, and keeps the 12-row bound that stops a screenful of full-width output
from being re-scanned on every hover.

⚠️ Selection spans are computed in CELLS, not text offsets: an xterm selection is
one contiguous run, so a token spanning a hard wrap also covers the indent cells
between its halves. A run that skipped them cannot be expressed, and would not
match what is highlighted.

Tests: `test/terminal-logical-line.test.ts` (8 cases: the indent drop, resolving
from either row, both mapping directions, soft continuations kept verbatim, no
over-reach past a short row, the row bound, final-row trimming, a missing row) and
5 in `terminal-touch-tap.test.ts` (the whole URL from either row, a token selected
across the wrap, `Line` spanning both rows, no reach into the next line). Removing
either half of the fix reds 5 and 8 of them respectively.

+ * The LOGICAL line a terminal row belongs to — the rows it spans, its text as one
+ * string, and a two-way map between that string and terminal cells.
+ *
+ * One definition, two consumers: the link provider matches its patterns over this
+ * text (`registerFilePathLinkProvider`) and touch selection measures words and
+ * whole lines with it (`_touchSelectionLogicalLine`). They MUST agree — a link that
+ * spans a wrap and a "Line" that stops at the screen edge is the same bug twice.
+ *
+ * Two kinds of continuation, and handling only the first is not enough:
+ *
+ *   1. **Soft wrap** — the emulator ran out of columns and flags the next row
+ *      `isWrapped`. It inserts nothing, so the row's text is joined verbatim.
+ *   2. **Hard wrap** — the program wrapped the text itself and emitted a real
+ *      newline, so nothing is flagged. A row that fills the last column is taken
+ *      as continuing into the next; that is the only trace a hard wrap leaves.
+ *
+ * ⚠️ A hard-wrapped continuation may carry the program's own INDENT, and joining
+ * that verbatim puts whitespace in the middle of the token being stitched. That is
+ * why an agent's numbered list —
+ *
+ *     1. https://github.com/users/someone/packages/container/p
+ *        ackage/thing
+ *
+ * — opened only `…/container/p`: the URL pattern stops at the space the indent
+ * contributed. So the leading whitespace of a HARD continuation is dropped, and
+ * `colStart` on that segment records how much, keeping the cell mapping exact. A
+ * soft continuation keeps its leading whitespace, since the terminal never adds
+ * any and it is therefore real content.
+ *
+ * ⚠️ Only the final row is trimmed. Continuation rows are read UNTRIMMED so each
+ * contributes exactly `cols` cells; trimming one would shift every later offset.
+ *
+ * The row span is bounded by `maxRows` (12 by default): this runs on every hover,
+ * and a screenful of full-width output would otherwise re-scan the viewport each
+ * time.
+ *
+ * @param {{getLine: (row: number) => any, length: number}} buffer xterm buffer.
+ * @param {number} row 0-based ABSOLUTE buffer row to expand around.
