docs: changelog and version scoping for 1.3.0 - #180

The release workflow writes only VERSION; this docs-only change supplies the
1.3.0 changelog section and names 1.3.0 where the documentation names the
current release or pair, so the README that PyPI shows for 1.3.0 is right at
the tag.

What changed

• CHANGELOG.md: ## 1.3.0 — 2026-10-06, taking in the Unreleased note. It
  covers Confirmed-bar receipt: versioned metadata from lowering decisions #173 (the confirmed-bar receipt; the capability receipt's request
  entries now read their timeframe, Heikin-Ashi flag and feed from the
  lowering), Order-shapes receipt: lowered order-call facts for closing-time order processing #178 (the order-shapes receipt, which no engine reads yet), Checked settings: string dropdowns with built-in display constants no longer break the settings receipt #179
  (a string dropdown with a built-in constant no longer breaks the checked
  settings; such an input is now "supported": false with no options, where
  1.2.0 wrote the constant's integer code or published the input as
  supported), License: the PineForge Source License 1.2; a funded-trader challenge, evaluation or simulated account is not Personal Trading and is investment capital #177 (the PineForge Source License 1.2), docs: render the active scoreboard from the facts tokens at pineforge-release 3e39d64 #174 (the scoreboard
  render) and CI: install the codegen docs-only gate, with a same-repository guard for forks #175 (repository CI only), with the pairing and migration
  steps. Codegen 1.3.0 supports only engine v1.3.0; engine v1.3.0's
  <pineforge/pineforge.h> is v1.2.0's (C ABI 4, engine_script_run_v19).
• Version scoping: README (pairing table row, describes line, engine
  src/source/ link, @pf-trace note, timing note, clone command and its
  output, "This section describes …", license badge 1.2), AGENTS.md and
  CLAUDE.md (identical edits), CONTRIBUTING.md, LEGAL.md (1.3.0 is the first
  release under 1.2), docs/PUBLIC_CONTRACT.md (the "unreleased (after 1.2.0)"
  markers name 1.3.0; the catalog asset is diagnostics_catalog-v1.3.0.json),
  docs/pine-cap-activation.md and npm/README.md. Lines that say what an
  earlier release shipped stay. The release scoreboard sentence and the pf
  markers are left to the release lane.

Compatibility

• Python and JSON contract: no argument, result key or envelope is added,
  removed or renamed. Since 1.2.0 the package's code changed only under
  pineforge_codegen/codegen/; __init__.py, errors.py, gate/glue.py and
  the diagnostics catalog (628 codes) are 1.2.0's files.
• Report keys: the engine's docker/run_json.py is the same file in engine
  v1.3.0 as in v1.2.0, so no report key is added, removed or renamed;
  metrics.equity.sharpe_tv / sortino_tv (EQUITY_REPORT_KEYS) are
  unchanged, and the engine's ADR-0001 keeps serialized report keys as they
  are.
• License: 1.3.0 is the first release under the PineForge Source License 1.2
  (a proprietary-trading firm's or funded-trader program's account, including
  a challenge, evaluation or simulated account, is not Personal Trading, and
  its capital, real or simulated, is investment capital). 1.2.0 shipped under
  1.1; releases up to and including 1.1.0 under "PineForge Codegen —
  License". LICENSE is the controlling text.

Verified

• The engine's 325 public corpus sources and the 277 gate fixtures, each
  transpiled in a fresh process with 1.2.0 and with this branch: with the
  confirmed-bar and order-shapes functions removed, 589 of 589 C++ files are
  byte-identical and the 13 expected refusals keep their messages; for all
  602, transpile_full()'s result and the transpile_json envelope without
  cpp are identical.
• Each of the 602 sources is transpiled or refused in under 0.1 s (max
  0.065 s) on CPython 3.14.6 on an Apple M4 Max.
• The engine tutorial with the quick-start C++ of this branch against engine
  main 7a1f01c0 (Linux x86_64, GCC 13): 9 trades, +738.20; 13 trades with
  the old sizing declared. Codegen 1.2.0 with engine v1.2.0 prints the same.
• git diff --check is clean, and the codegen docs-only classifier accepts
  the diff (codegen-docs-only/v1).

Not changed here: the pyproject.toml comment still names license 1.1 (not
docs-only).

Release grades (second commit)

The README's release sentence moves to the releases[1.3.0] tokens, its main-scoreboard lines re-render, and the changelog says which registry baseline grades 1.3.0, all rendered from pineforge-release facts/facts.json at ff21de0 (#32): 7,982 excellent / 7 strong of 7,989 graded probes, 0 below strong, on engine 7a1f01c0 and this repository at 3e50082 (#178 adds only receipt functions; the rest is documentation). lab facts check and --github-render pass.

Gate

Codegen docs-only basis (codegen-docs-only/v1, 9 Markdown files): receipt recorded for this head before the push (PASS (docs-only), engine 7a1f01c0 / codegen d20a02d); no sweep. The CI gate job posts the required status.
