Name the apparent wind va, va_vec and va_dist everywhere except the public API

[1-Bort-1]

TL;DR

Every local, argument, test, example and doc now uses the #147 convention for the apparent wind: va is the speed, va_vec the vector, va_dist the per-panel speeds and va_vec_dist the per-panel vectors. It is the first of the two PRs you picked with option A on #337, so nothing public changes: struct fields, keywords, the body_aero.va property and the YAML keys stay for the stacked breaking PR.

What changed

quantity	was	now
speed [m/s]	v_a, va_norm, va_mag, va_ref_mag, va_panel_mag, filament vel_mag argument	va, va_ref, va_panel
3-vector	vector va locals, vel_app, va_ref_vector, va_1/2, dva_1/2, delta_va, omega_va, va_b_0	va_vec, va_ref_vec, va_vec_1/2, dva_vec_1/2, delta_va_vec, omega_va_vec, va_vec_b_0
per-panel speeds	va_norm_dist	va_dist
per-panel vectors (P×3)	va_dist, va_distribution	va_vec_dist

va_dist used to mean the P×3 matrix and now means the speeds. calc_norm_dist!(va_dist, va_vec_dist), calculate_results, update_effective_angle_of_attack! and update_gamma_candidate! take both, so the P×3 rename ran first.

v_a_dist did not fit the convention: it holds |(va + v_ind) × y_airf|, the in-plane relative speed that feeds the dynamic pressure, not the apparent wind speed (solver.jl, update_gamma_candidate!). Its locals and arguments are now v_rel_dist, after v_rel in panel_aerodynamics.jl. Calling it va_dist would have been wrong.

Where public keywords meet renamed locals, the call names both: plot_polars(...; v_a=va) and BodyAerodynamics(...; va=va_vec). The Makie extension's arrow now uses va_unit rather than a scalar va, so the stacked PR's v_a= → va= rename does not shadow it.

Tidied in files this PR already touches: the extension carried a second, unattached generate_polar_data docstring that duplicated the one in plotting_helpers.jl and still said v_a, so it is deleted. Renamed lines past 92 columns are wrapped, and error messages name the new arguments (set_va!(body_aero, va_vec), va_vec_dist must be shape ...).

Left alone, and why

• Public API, deferred to the stacked breaking PR: struct fields (Panel.va, _va, has_distributed_va, v_a_dist, _va_dist, va_unrefined_dist, BaseResult.va_norm_dist, SemiInfiniteFilament.vel_mag). SymbolicAWEModels reads ._va, panel.va and lr.v_a_dist. Also deferred: body_aero.va, the va=/v_a=/va_idxs= keywords, the "va_ref" result key, and the YAML keys airfoil.v_app and condition.wind_speed.
• Not the apparent wind: va1..3 (components), va_magw_dist and v_acrossz_dist (projections), the *_prescribed_va force locals, and va/vb in obj_slice.jl (triangle vertices).
• Kept as is: Uinf in test/thesis_oriol_cayon.jl, a port of the thesis code where it is a vector in some functions and a scalar in others. The example plot titles, which are also the saved figure names, now say _va_ instead of _v_a_.
• No changelog entry: nothing a caller writes changes. The stacked PR carries the BREAKING: entry.

Verification

• Reproduced first: n/a, a rename with no behaviour change. No test assertion changed; the tests were renamed like everything else.
• juliaserver, all green: body_aerodynamics/test_body_aerodynamics.jl, body_aerodynamics/test_results.jl, filament/test_semi_infinite_filament.jl, filament/test_bound_filament.jl, wake/test_wake.jl, panel/test_panel.jl, solver/test_solver.jl (34/34), solver/test_flow_curvature.jl, solver/test_unrefined_dist.jl, solver/test_forwarddiff.jl, solver/test_moment_units.jl, plotting/test_plotting.jl (93/93), settings/test_settings.jl, bench.jl (21/21). The last round's error-message and test-helper fixes were rerun on a fresh session: body_aerodynamics, results, semi_infinite_filament, wake, test_solver and flow_curvature.
• examples/rectangular_wing.jl ran to the end, plots included (plot_polars(...; v_a=va)). The other examples and mwes were not run; a per-file check found every renamed local defined and no v_a left except as the public keyword.
• Docs build clean (docs/make.jl without deploy, test environment) · up to date with main (246237a) · no REUSE in this repo
• Local CI mirror (agent ci-local, Julia 1.12) started after the push, result not in yet · GitHub CI: see checks
• Benchmark: n/a
• Risk: a rename slip in an example I did not run. CI does not run them either.

Scope

+353 / −365 across 36 files, all renames plus the deleted duplicate docstring (−23) and line wraps. Stack: 1/2. The breaking public rename is #348, stacked on this PR.

Good

• The v_rel_dist rename is right: solver.jl:763 fills lr.v_a_dist with the smoothed in-plane speed, and solver.jl:776 divides by it to get gamma, so calling it va_dist would have been wrong.
• The swap of va_dist (was P×3, now speeds) is done cleanly: calculate_results, update_effective_angle_of_attack!, calc_norm_dist! and the test/bench.jl call now take va_vec_dist, va_dist in the same order in signatures, docstrings and callers.
• Struct fields stay as the card says: lr.v_a_dist, br.va_norm_dist, sol._va_dist, _va, panel.va and SemiInfiniteFilament.vel_mag are untouched, and reinit! still calls set_va!(body_aero, va, omega) with the public va keyword.
• The Makie arrow change keeps behaviour: -2*max_chord*va_unit equals the old -2*max_chord*va/va_mag, and it frees the name va for the stacked keyword rename.
• Deleting the loose generate_polar_data docstring in the extension is in scope: it was attached to nothing, repeated plotting_helpers.jl:76 and still said v_a.
• What is left over matches the card's list: a grep for v_a|va_norm|va_mag|vel_app|va_distribution finds only public v_a= keywords, the struct fields, va_magw_dist, the thesis port and old CHANGELOG entries.
• The long lines are wrapped: none of the added lines in src/body_aerodynamics.jl or src/panel_aerodynamics.jl goes past 92 columns.

Not good

• src/plotting_helpers.jl:93 — This renames the generate_polar_data keyword from v_a= to va=, which contradicts the card's claim that keywords wait for the stacked PR and the rubric's rule that keyword names are API. The card never mentions it, and any outside caller using v_a= now gets a MethodError. Keep v_a= here and move this to #348.
• test/bench.jl:97 and :189 were renamed but are still well past 92 columns, although the card says renamed long lines were wrapped.
• The errors at body_aerodynamics.jl:340/352 name va_vec/va_vec_dist, but the argument is va_input and users pass the public va=, so the message points to a name no caller writes.
• test/thesis_oriol_cayon.jl:77-80 still has a scalar local v_a = norm(Uinf); the card only says Uinf was kept, and this one-name rename to va fits the convention.
• Only rectangular_wing.jl was run; linearize_check.jl (va_vec_b_0 in y0) and billowing.jl are the untested renames most likely to hide a slip, and CI does not run them.
• The example plot titles, which are also the saved file names, change from _v_a_ to _va_. Anyone scripting over saved figures sees new names, so a changelog line may be worth it even though no API changes.
