Cut the Pine source layer out of BacktestEngine (R4-C, roadmap slice B; paired with codegen) - #253

…GINE) (#300)

Audit of every README and doc page of pineforge-engine against engine main
35db01c and the live measurement; each change names its source.

What was wrong, and the source of the truth:

- Parity numbers were the retired 4,190-probe round-39 era (badges, hero,
  scoreboard, lane table, contributing-llm.md, design/progress pages). Now the
  active baseline pineforge-parity-baseline-20260929-engine-35db01c8 (snapshot
  sha256 47cec517..., population cf857209...): 8,006 probes, 7,989 graded =
  7,905 excellent + 84 strong, 17 TradingView-side anomalies excluded,
  18 lanes, 2,759,431 TradingView trades (population tvTradeRows / 2). The
  "2.8M matched" count has no source in the snapshot and is gone. Public
  corpus: 311 excellent + 1 declared anomaly (scripts/check_corpus_parity.sh
  pinned headline; parity step of the XAU-CAL lane job on this tree), and
  anomaly-equity-mirror-strategy-equity-01 is that anomaly (it does not
  match trade-for-trade on the pinned corpus).
- Versions: no 1.0.0, 0.14.0 or rc tag exists (git tag; gh release list).
  CHANGELOG's "## 1.0.0" becomes "## Unreleased" and lists #292-#298, which
  it lacked (squash messages 7f807b9..35db01c); "34 more" PF_API is 39.
  README Releases: v0.13.1 entry added, v0.13.0 line corrected, the merged
  live/abi-v4 "Unreleased" line and the 1.0.0 line replaced. Pages that
  framed 1.0 as shipped now say planned.
- Front door 1 could not run: pineforge-codegen has no CLI (0.10.4 or main),
  PyPI 0.10.4 output does not compile against main (cc log), a plain
  -lpineforge link drops the runtime C ABI (run_strategy.py refuses it), and
  run_strategy.py needs --ohlcv/--no-trim-output without the corpus. The new
  block ran end to end from a clean clone (14 trades on the tutorial feed).
- Prerequisites: floating-point std::to_chars (src/str_utils.cpp:55) needs
  GCC 11 / libc++ 14; ctest --test-dir needs CMake 3.20; examples need
  -DPINEFORGE_BUILD_EXAMPLES=ON; the install also ships libpineforge_kernel.a.
- MCP section: the image, hosted server and npm package run engine 0.13.1 +
  codegen 0.10.4 (pineforge-release v0.1.25 notes); hosted server and npm
  package descriptions corrected from their live/ published sources.
- Benchmarks: every number reproduces (check_provenance 163/163); framing
  fixed (commit and method named, PineTS has had strategy.* since 0.9.17),
  recipes state their prerequisites, two wrong failing-gate cells fixed,
  personal host name scrubbed from 14 Google Benchmark JSONs with the
  manifest sha256 values updated (origin_sha256 keeps the measured file).
- Reference pages: native-engine.md, pine-to-native.md, coverage.md,
  pine_v6_coverage_detail.md, the contract pages, ci.md and the design notes
  described removed members and pre-#253/#254 behaviour, stale counts
  (src 48 -> 53 .cpp, 66 -> 70 indicator classes, 43/33/10 -> 46/35/11
  NativeRunSpec fields, floors 786/298 -> 790/300), wrong anchors, drawings
  as absent, and transpiler status of an old codegen (now "on codegen main,
  not in a release yet" where it differs from v0.10.4).
- Hygiene: internal host names, personal paths, private-repo references and
  campaign tool names marked or removed; the banner image's stale
  "V0.8.0 / 245/246 / 0 engine bugs" strip removed; a dead
  pineforge-workflow-live link replaced by the public pineforge-live repo.
- Two orphan pages, docs/cheatsheet-runtime-and-execution.md and
  docs/tv-parity-probe-spec.md, were wrong in their load-bearing claims
  (17 removed engine members, pointvalue/FX/slippage claims) and nothing
  linked them: deleted.
- Sample outputs were stale: every page and the tutorial README printed the
  tutorial MACD as 49 trades / -190.85; since 650b0cb (in v0.13.1) the report
  counts the range-end close, and every harness prints 50 / +569.97 (runs on
  a clean clone of this branch). examples-python-sweep.md's 10000 capital
  could not pay for its 1-BTC order (every combo 0 trades): 100000, output
  re-measured. examples-multi.md output format matches multi.py; the
  magnifier A/B page shows today's run. The report fields script_tf_ratio
  and needs_aggregation print their contract values again on this base
  (FIX-E1E2, #299; tutorial/run_mtf.py Table A: ratio 1/1/4/16, agg
  0/0/1/1), so the pages state them as plain facts.
- Doxygen: `file:line` in four pages autolinked to a dead "file:line" URL;
  spelled `path:line` now. Build: 0 warnings.

Review fixes (REVIEW-DOCS-ENGINE-final.md, verdict MERGE-WITH-FIXES, of the
first version of this change, 79bd84c1 + 6cb01aa0): its five P2 findings with
the reviewer's fix text, and every P3 row but the last.

P2
1. docs/pages/metrics.md: a timestamped FX curve no longer fails closed for a
   leveraged position across a rate change; that position takes the
   broker-open margin checkpoint at the step bar's open
   (tests/test_affordability_fx.cpp:152-154, :781).
2. docs/pages/report-schema.md: the #254 caveat sat inside the table, so the
   bar_magnifier_enabled row rendered as text; it now follows the table.
3. CONTRIBUTING.md, docs/pages/getting-started.md: compiler minimums are the
   ones README.md states (floating-point std::to_chars, src/str_utils.cpp:55:
   libstdc++ from GCC 11, libc++ 14, macOS 13.3; g++-9 and g++-10 fail).
4. docker/README.md: the sample is the published image's run (50 trades,
   17/33, +569.97, trade 1 entering 1777488300000).
5. docs/pages/mtf.md: expected Table A says main prints 0 in ratio and agg?
   until the #254 regression is fixed.

P3
- configuration.md, CHANGELOG.md, coverage.md: v5 scripts do not "keep" host
  defaults (both codegens refuse //@Version=5); code from an earlier codegen
  and a hand-built PineStrategyConfig do.
- streaming.md: "Every strategy_stream_* call above" (create/free return no
  status).
- examples-multi.md: a module also exports std::piecewise_construct.
- integration-cmake.md: EXACT 0.13.1 also matches a git-checkout build of
  main; the ABI promise starts "From 1.0.0".
- ffi-python.md, tutorial-macd.md: the mirror covers the report structs, not
  every struct (ffi-python.md:15-17).
- configuration.md: tracing costs one branch per traced call when disabled
  (report-schema.md:180), not zero.
- benchmarks/results/raw/README.md: "Two edits were made" (host_name was
  rewritten in every Google Benchmark file); benchmarks/README.md: the
  maintainer fetch runs with the campaign environment sourced. Wording only.
- AGENTS.md: the configure line exports compile commands, which the receipt
  check needs; AGENTS.md and docs/ci.md: promote-baseline.yml is installed
  from the campaign copy, not unchanged (31 lines differ).
- docs/ci.md: the debug profile also skips the twin-parity guard
  (TWIN_PARITY_PROFILES).
- mtf.md, timeframes.md: "reported for an engine fix" dropped (no public
  issue).
- native-feature-parity.md: the C API "landed on main", not "shipped".
- tutorial/README.md: Table B's script_tf_ratio prints 0 on main until the
  #254 regression is fixed.

Not changed here: benchmarks/results/summary.md and trade_comparison.md keep
the first version's text (hand edits of generated output; fixing the generator,
benchmarks/compare.py:361 and scripts/verify_corpus.py:1403, is an
engine-lane follow-up). No benchmark number or results file changes beyond
the raw/README.md and benchmarks/README.md wording above: BENCH-REFRESH is
re-measuring the benchmark.

Rebased onto 4dc496d (FIX-E1E2, #299), squashed to one commit. docs/ci.md
states the new floors: PR registration 773 (debug, sanitizers) and 782
(native), full-run release 792 and kernel 300 (scripts/ci_verify.py:320,
:594, :638). The one rebase conflict, a native-refactor-progress.md row,
keeps main's re-anchored lines and this change's host-name removal.
