docs(dev): drop dead links to unwritten local-dev flow pages

[mesutoezdil]

docs/dev/local-development.md linked to 4 per-flow pages that were never written. Removed the dead links and pointed readers to the Topologies and Install paths sections on the same page.

Tested: no remaining dead links, ran ./tools/ci/check-docs (0 errors).

This will need a rebase before merge - repo does have all of these files - they just were blocked by our internal mirror accidentally (we retired the mirror and have to manually bring them over)

[mesutoezdil]

@sbaum1994 does the same internal mirror issue apply to imports.yaml and .gitlab-ci.yml? opened #258 and #260 assuming those are permanently internal and not present in this public snapshot, want to confirm before those merge

[pdmack]

This PR is one of four that together fix the lychee link check failures currently blocking CI on other PRs (e.g. #252). Verified locally: with #240, #241, #242, and #261 all applied, lychee --offline and fern check both pass with zero errors.

Note: broader broken-link issues remain visible via fern check --broken-links (14 additional errors in nav-tree resolution, pre-existing and out of scope here).

@sbaum1994 -- can you review and approve so these can merge?
