op-codegen-pipeline: klickweg harvest bridge — wire the board's nav to ruff #62's Rails navigates_to harvest

[AdaWorldAPI]

What & why

The board's klickweg connectivity was verified against a hand-authored edge table (op-server::nav::NAV_EDGES, derived from the ClassView association graph). ruff #62 shipped the Rails navigates_to harvest (two shapes: ERB link_to/button_to clicks + controller redirect_to redirects). This wires the harvest into the pipeline so the klickweg becomes harvest-derived rather than hand-authored — closing the loop the klickweg thread was about.

New op_codegen_pipeline::nav_harvest

• harvest_klickweg{,_with_report}(app_root) — runs ruff_ruby_spo::extract_nav_edges over an OpenProject Rails source tree, restricted to the served screens (OPENPROJECT_SCREENS = work_packages, projects).
• klickweg_pairs(edges) — the shape-agnostic (source, target) connectivity graph (ERB + redirect edges between the same screens collapse to one pair).
• RESOURCE_TO_CONCEPT / concept_for — the 1:1 bridge from Rails resource stems (the harvest vocabulary) to op-server ClassView concept names (work_packages→ProjectWorkItem, projects→Project), so the harvested graph and the ClassView graph are provably the same graph under the map.

Proof — tests/nav_harvest_probe.rs

Over a synthetic Rails fixture (tests/fixtures/rails_nav/, no proprietary source):

1. the harvested screen pairs are exactly the board klickweg (work_packages ↔ projects, both directions) — i.e. the harvest reproduces what NAV_EDGES encodes by hand;
2. both harvest shapes fire (ERB click + controller redirect);
3. every served screen bridges to a ClassView concept.

op-server::nav::NAV_EDGES gains a doc note recording that it is the baked mirror of this harvest, regenerating from the harvest once the OpenProject source is in the pipeline input.

Status

Additive — new module + test + fixture; no existing behavior changed. op-codegen-pipeline suite green (incl. 3 new probe tests); new code is clippy-clean (remaining warnings are pre-existing, in git-dep crates). This is the consumer half of the ruff #62 arm; the producer (Ruby harvester) is already on ruff main.
