fix(terminal): keep sentences and script commands out of spaced paths

A side-by-side sweep of master and this branch over about 590 realistic lines
found more shapes where a spaced candidate swallowed prose or a command:

- An earlier word that is a lowercase connective or verb (and, or, to, in,
  the, is, has, contains, then, as and a few more) now makes the candidate a
  sentence, for own-line, list-marker and labelled forms alike:
  `/home/me/proj contains a.md`, `- /tmp/out has the logs in run.log`,
  `Path: /home/me/proj/out contains a.md`, `Files: src/components and
  utils/x.ts`, `Wrote: 3 files to docs/design notes/overview.md`. `at` and
  `of` stay out so screenshot names and `Copy of report.docx` still link
  whole; a name such as `Pros and Cons.md` splits as on master.
- A bare `=` word is refused like the arrows.
- An executable under `scripts/` or `tools/` is refused like one under
  `bin/` (`/home/me/proj/scripts/deploy prod.yml`).
- An earlier word holding an extension anywhere (`a.ts#L12`) ends the path.

The two residuals pinned earlier (`/home/me/proj contains a.md` and
`Files: src/components and utils/x.ts`) now return master's links.
