Closes #824

Stacked on #828.

Change

Since #808, --js code that fails only gives the message. With --verbose it now also tells where, when that is in a file of the user, like a module loaded with r():

 ❌ The code of --js failed for the piped data: TypeError: undefined is not an object (evaluating 'value.nope.deeper')
    at helper.js:2:15
    No further processing.

• It is the first place in the stack above the code of RexReplace, which is where the code of the user runs. Places in Node itself are skipped. The path is relative to the working folder.
• Code in the command itself (like nope()) has no such place, so nothing more is told.
• It works the same on Node and Bun, which write the stack in different ways.

Tests

test/fix/824.test.js is new. yarn test-ci passes.

From the review of 23 October.

After the review of 24 October

• Reading the stack is in a try, so a thrown value whose getters throw no longer crashes the run with --verbose. Before, it undid Better error handling of --js code for none error throws to close #822 #828 for that flag.
• Each line of the stack is read on its own, with the place at the end of the line, so a path with parentheses, like a (copy)/helper.js, is read as a whole.
• Only absolute paths count, so the frames of Node itself (node:internal/…) and of code run with eval are not shown as fake ../../ paths. Paths in node_modules are skipped too.
• Checked on Node and Bun: a module, a path with parentheses, a module that is not there, new URL("x"), nope() and a Proxy that throws.

After the review of 24 October

Closes #846

• A stack line without a function name, like at /dir/a (copy)/top.js:1:11, is read first as that form, as the place comes right after at. Before, /dir/a ( was read as the name of a function, and the place was not told. A line with a name has its place in parentheses at the end, and is read as that form.
• Checked on Bun and Node, with code at the top of a module and in a function, in a folder with parentheses in its name.

Follow-up

• The error is on its own line under the file, with no colon:

 ❌ The code of --js failed for the piped data
    TypeError: undefined is not an object (evaluating 'value.nope.deeper')
    at helper.js:2:15
    No further processing.

• stackPlaces() is now stackTraceLocations(), and stackPlace() is userCodeLocation().
• The branch is rebased onto fix/822 once, so the new tests of Better error handling of --js code for none error throws to close #822 #828 get the new layout too.
