Raise floors to Julia 1.11 and GeometricBase 0.15

[michakraus]

Raises the floors to Julia 1.11, GeometricBase 0.15.0, CompactBasisFunctions 0.4.2 and QuadratureRules 0.2.2, because GeometricBase 0.15 declares its stubs public and requires Julia 1.11. The version goes from 0.3.0 to 0.3.1. This is part W3 of the plan to make the GeometricBase stubs public, for SimpleSplines.

The PR title has 50 characters or fewer. Three of the commit subjects are longer than 50 characters. A squash merge under this title keeps the house limit, with no rewrite of the branch history.

Pre-PR verification

Fixed: nothing. No defect needed a change.

Unresolved (nits):

• In CHANGELOG.md, ### Bug Fixes comes before ### New Features under [Unreleased]. The released sections use the other order. Fixed in c26e041: ### Bug Fixes now comes after ### New Features.
• The three commit subjects are longer than 50 characters. A squash-merge under a short PR title fixes this.

Pre-existing: none.

Checked and clean:

• The floors match the registered gate releases: GeometricBase 0.15.0, CompactBasisFunctions 0.4.2, QuadratureRules 0.2.2, Julia 1.11. Each of these releases requires julia = "1.11.0 - 1".
• test/ and docs/ have no bound that needs a change.
• No VERSION gate against 1.10 or 1.11 remains.
• The package resolves and loads on Julia 1.11.9 and 1.13.1.
• On 1.11.9, both the local function and the closure form of the kernel = :project call infer a concrete CirculantMass. So the deleted comment in test/mass.jl described only Julia 1.10.
• Aqua.test_piracies and test_ambiguities pass on 1.13.1.
• test/mass.jl is formatted.
• No stale or historical prose was found.
• The CHANGELOG entry is present.

Not checked:

• Allocations and inference beyond the probe above, because no .jl source line changed.
• Aqua on 1.11.
• The CI test matrix (§F clause 6) and the full suite, which CI runs.

Critic

Critic 1a: Verdict: PASS. Clauses 1–5 met, no blocking defect; clause 6 open until the PR's CI. Evidence (clause: result): §F 1 julia "1.10" → "1.11" in the root, none added in test/ or docs/ — PASS; §F 2 GeometricBase "0.14.8" → "0.15.0", CompactBasisFunctions "0.3, 0.4" → "0.4.2", QuadratureRules "0.2" → "0.2.2", each the latest registered gate version, other bounds unchanged — PASS; §F 2 fresh resolve on Julia 1.11 (GeometricBase 0.15.0, CompactBasisFunctions 0.4.2, QuadratureRules 0.2.2, ContinuumArrays 0.21.5, JET 0.9.20; loads on 1.11.9) — PASS; §F 3 0.3.0 → 0.3.1 — PASS; §F 4 CHANGELOG entry present — PASS; §F 5 no VERSION gate — PASS; §F 6 open, local substitute run-tests.jl affected PASS in 75 s; named mutants for clauses 1 and 2 CAUGHT.

Critic 1b: Verdict: PASS. Evidence: §F 1 PASS; §F 2 PASS (registry has 0.15.0, 0.4.2 and 0.2.2); fresh resolve on 1.11 PASS; §F 3 PASS; §F 4 PASS; §F 5 PASS; §F 6 open, local proxy on 1.13 PASS in 74 s (Aqua 11/11, JET 10/10, Meshes 62/62, Boundary conditions 68/68, Periodic B-spline bases 4586/4586, Clamped and recombined bases 58142/58142, Mass operators 1041/1041, Spline quadrature 340/340, Tensor products 408/408, Polar splines 454/454, Doctests 1/1); named mutants for clauses 1 and 2 CAUGHT (the clause-2 mutant also fails a fresh resolve); docs class rule does not apply (docs env needs no unreleased package); scope is Project.toml and CHANGELOG.md only.

Both critics' Other defects (the stale test/mass.jl comment, and the three-sentence CHANGELOG entry) are fixed in cf76666 and 344f293.

Suite counts

• Julia 1.13.1, Pkg.test(), check-bounds auto: 64723 passed, 0 failed. GeometricBase v0.15.0, CompactBasisFunctions v0.4.2, QuadratureRules v0.2.2.
• Julia 1.11.9, Pkg.test(), check-bounds yes: 64723 passed, 0 failed, same versions.

Both runs are at 1a75969. The later commits change only a CHANGELOG entry, the order of its sections, and a two-line comment in test/mass.jl.

Known issues added

None.
