Test and support Julia 1.12 and 1.13, drop 1.11

[1-Bort-1]

TL;DR

CI now tests Julia 1.12 and 1.13, [compat] says julia = "1.12, 1.13", and a Manifest-v1.13.toml.default resolved under 1.13.0 takes the place of the 1.11 one. This is unit vsm of 1-Bart-1/Agents plans/julia-1-13.md; before this, compat said "1.10, 1.11" while CI already tested 1.12.

What this repo had, of the five steps

Matrix. Only the test job in CI.yml names minors: its version list goes from 1.11/1.12 to 1.12/1.13. The three include: entries (ubuntu coverage, windows, macOS) name 1.12, which stays, so they don't change. The thread mentions a second job naming minors, but there isn't one: the docs job uses setup-julia's default and setup-test.yml is on '1', so both stay as they are. The job carries fail-fast: false; the plan puts that in its own cleanup: PR, not this one.

Compat. julia = "1.10, 1.11" → "1.12, 1.13". There is no SHA entry, so the 1.13 SHA 1.0 bump needed nothing.

Manifests. Minimal resolve, not widened. Re-resolving the 1.12 .default under 1.12.7 moved one line: the package's own recorded version, stale at 4.0.0, is now 5.1.1. The 1.13 .default was seeded from that and resolved under 1.13.0. Only stdlibs and their JLLs moved (SHA 0.7→1.0, LinearAlgebra/Pkg/SparseArrays 1.12→1.13, LibCURL, OpenBLAS_jll, SuiteSparse_jll, …, plus PCRE2_jll added). No registry package changed. The 1.11 .default is deleted. It is half the size of the new one because 1.11 has no [workspace], so it never held the test/docs/examples deps.

Scripts and prose. bin/install's selector, its supported-version check, the Julia it installs when none is found and its manifest cleanup list all move to 1.12/1.13. bin/update_default_manifests moves the same way. The branch that copied the main manifest into each sub-project only ran on 1.11 (no workspaces there), so it is deleted instead of renamed. README.md said "Julia 1.10 or later" and docs/src/index.md said "1.11 or later"; both now say 1.12.

Found on the way

• bin/install runs juliaup default when no julia is on the PATH. §2 of the agent rules says the scripts never do that. I only changed the version it names; fixing the behaviour is a separate cleanup:.
• Step 3 of the plan says JULIAUP_CHANNEL=1.13 juliaserver launch ., but that still came up on 1.12.7 here. juliaserver starts the session with tmux new-session, which takes its environment from the tmux server that is already running, not from the command that launched it. I restarted Julia inside this worktree's own pane as julia +1.13 instead. The plan's other units will hit the same thing. (juliaserver also prints md5: command not found / bc: command not found on every call on this box.)
• test/airfoil_aero/test_live_polar.jl's refresh_allocs docstring explains a workaround with "on Julia 1.11 @allocated boxes a Float64". 1.11 is no longer supported, but the test still passes on 1.13 as written, so I left it alone.
• CHANGELOG.md gets the same ## Unreleased header Deprecate ObjAdapter's copy of the mesh inertia integral; SymbolicAWEModels owns it #325 adds, so whichever merges second has a trivial conflict.

Verification

• Reproduced first: n/a — version move, nothing to reproduce
• ./bin/install -y +1.13: exit 0. All projects instantiated on the first try, precompile OK, Makie extension loaded, settings/test_settings.jl smoke test passed
• ./bin/install -y +1.12: exit 0, same steps
• Julia 1.13.0 session, test env: Aqua.jl + solver/test_solver.jl + airfoil_aero/test_live_polar.jl, 137/137 pass
• Local full suite (agent ci-local, Julia 1.12.7 cell): PASS in 10 min · GitHub CI: starts when the PR opens
• Docs build (docs/make.jl, Julia 1.12.7): clean, apart from the size warnings on private_functions.md and functions.md that main already has
• Up to date with main (23f129b) · no REUSE in this repo
• Risk: the macOS/Windows jobs stay on 1.12, so 1.13 is tested on ubuntu only.

Scope

+3149 / −1478 across 10 files. The manifests account for 3122 added and 1451 deleted. The rest is 2 lines in CI.yml, 2 in Project.toml, 36 changed in bin/install (6 of them the deleted 1.11 branch), and one line each in bin/update_default_manifests, README.md and docs/src/index.md, plus the changelog entry.

Independent review (advisory)

Verdict: APPROVE WITH COMMENTS · 1 inline, 0 off the diff

Good

• Matches the card: git diff --stat 23f129b HEAD shows the same 10 files and +3149/−1478, with no changes the card leaves out
• Only the test job in CI.yml names versions (checked the file on 23f129b); the three include: entries correctly stay on 1.12
• Both manifests changed as small as claimed: the 1.12 .default moves only the package's own version 4.0.0→5.1.1, and the 1.13 one has julia_version = "1.13.0" and includes the test/docs/examples deps (Aqua, Documenter, CairoMakie)
• Removing the 1.11 sub-manifest copy branch is safe: _sub_manifest is used nowhere else in bin/install, and MAIN_MANIFEST/MAIN_DEFAULT still take their name from _julia_major
• .gitignore covers Manifest*.toml, so only the .default files are tracked, as §9 requires; the 1.11 .default is deleted rather than kept around (§2)
• Found-on-the-way items are recorded instead of fixed quietly (juliaup default, juliaserver tmux environment, the stale 1.11 docstring), and the macOS/Windows-on-1.12 risk is stated

Not good

• CHANGELOG.md:7 — "Requires Julia 1.12 or 1.13" is wrong: compat "1.12, 1.13" also allows 1.14 and later, and README/index.md say "1.12 or later". Users reading the changelog get a narrower range than the package actually accepts; "Requires Julia 1.12 or later" would match.
• julia = "1.12, 1.13": Julia compat is caret-style, so "1.12" already means [1.12, 2.0) and ", 1.13" adds nothing; harmless, but it reads as an upper limit it does not set
• docs/src/functions.md:109 still links the Julia package docs under pkgdocs.julialang.org/v1.11/; it is outside the files this PR opens, so it belongs in the follow-up cleanup:
• The CHANGELOG.md ## Unreleased header will conflict with #325, as the card says; whichever PR merges second has to fold its entry under the other's header, not add a second header

MINOR: "Requires Julia 1.12 or 1.13" is wrong: compat "1.12, 1.13" also allows 1.14 and later, and README/index.md say "1.12 or later". Users reading the changelog get a narrower range than the package actually accepts; "Requires Julia 1.12 or later" would match.
