K1 (#369) added include/pineforge/native_calc_point.hpp, installed by the
include/pineforge rule in CMakeLists.txt with the other headers. Name it in the
1.5.0 CHANGELOG entry and in the native C++ API list of
docs/pages/public-contract.md (new in 1.5.0). Docs only.

Squash of #374 (3 docs commits on 2394ba2, tree 776a3cb). The CHANGELOG entry is dated 2026-10-12, the tag date; the first commit's "2026-10-13" below is superseded. The three commit messages follow verbatim, so their doc-revert namings are kept.

docs: prepare the 1.5.0 release (changelog, current pair)

Date the CHANGELOG's 1.5.0 entry 2026-10-13 and give it the release link
line naming the paired pineforge-codegen 1.5.0, keeping the recorded-outputs
and call-scoped-report content unchanged. Add the release's other
user-visible changes: the test inputs and strategy scripts moved to a
private repository, where a test that needs one skips with the pinned
message naming the missing file; the LEGAL.md "Data not distributed"
section; and the private-fixture overlay the maintainers run the
verification with.

README: the current-release block, the codegen command-block pointer, the
C ABI counts line and a new v1.5.0 Releases bullet now name 1.5.0; the
v1.4.0 descriptions, scoreboard and benchmark measurements stay untouched.

The current-release block's 1.4.0 sentence from 5a1ad3a ("The release notes
cover typed and unresolved provenance, coded failures, checked settings,
adapter fixes and chart-clock live input") is replaced on purpose by the
1.5.0 sentence that lists what 1.5.0 covers; that 1.4.0 summary stays in the
Releases list (the v1.4.0 bullet) and in CHANGELOG.md's 1.4.0 entry.

docs/pages/public-contract.md: the 1.5.0 paragraph follows the 1.4.0 one
and the same-version pairing line now says 1.5.0.

Scoreboard and benchmark numbers are untouched; no file outside these
three changes.

docs: 1.5.0 is released: status words, HPO note

The CHANGELOG's 1.5.0 entry gains its HPO bullet: pineforge-hpo 0.13.2
pins pineforge-codegen <1.4, and HPO support for codegen 1.4 and 1.5
(enum options as Enum.member tags) comes in pineforge-hpo 0.14.0.

Five files that still called 1.5.0, or a 1.5.0 feature, unreleased or
targeted for it now read as released once the tag lands:
docs/pages/abi-stability.md (the RunFailureCode exception, the
symbol-inventory counts line, the recorded-outputs line),
docs/pages/index.md (its counts line, matching the README wording),
the run-failure page (the outputs and selected-window rows' status, the
two 1.5.0 outputs reasons, and the 24 catalog rows that said none was
released), docker/README.md (the recorded-outputs section) and
docs/outputs.md. Only the status words change; "not part of 1.4.0"
stays where it is true history, and no number, claim or other sentence
moves.

No file outside these six changes.
