kingchenc 94cab88278 E3: add community health files
The repository had no contributor-facing documentation or automation
config. Add the standard set:

- CHANGELOG.md (Keep a Changelog format, 0.1.0-0.1.4 plus Unreleased)
- CONTRIBUTING.md (build/test steps, change standards, PolyForm-NC note)
- SECURITY.md (private reporting, supported versions)
- CODE_OF_CONDUCT.md (Contributor Covenant 2.1)
- .github/ISSUE_TEMPLATE (bug report, feature request, config)
- .github/PULL_REQUEST_TEMPLATE.md
- .github/dependabot.yml (cargo, npm, pip, github-actions — the last
  keeps the D1 SHA pins current)
- .github/CODEOWNERS

# Changelog
All notable changes to Wickra are documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [Unreleased]
### Added
- `TickAggregator::with_gap_fill` — opt-in mode that emits a flat placeholder
candle for every empty bucket between two ticks, keeping the candle series
evenly spaced for downstream indicators.
- CSV reader: a leading UTF-8 byte-order mark is stripped, fields are trimmed,
and the header is validated against the required OHLCV columns.
- CI: an `msrv` job that builds and tests the workspace on Rust 1.75 and the
node binding on Rust 1.77.
- Community health files: `CONTRIBUTING.md`, `SECURITY.md`,
`CODE_OF_CONDUCT.md`, issue / pull-request templates, `CODEOWNERS`, and a
Dependabot configuration.
### Changed
- `TickAggregator::push` returns `Result<Vec<Candle>>` (was
`Result<Option<Candle>>`) so a single tick can yield a closed bar plus gap
fillers.
- `Resampler::push` returns `Result<Option<Candle>>`: a candle in a bucket
earlier than the open bar is now rejected as out of order.
- Aggregated candles are finalised through the validating `Candle::new`, so a
volume that overflows to a non-finite value is surfaced as an error instead
of producing a poisoned candle.
- All GitHub Actions are pinned to commit SHAs; the four publish jobs run in a
protected `release` environment.
### Fixed
- `Timeframe::floor` no longer overflows for timestamps near `i64::MIN`.
- The aggregator rejects same-bucket ticks that arrive out of order instead of
silently overwriting the bar's close with a stale price.
- The Binance live stream reconnects with exponential backoff, skips non-kline
frames, applies a read timeout and message-size limits, and tracks a closed
flag.
- Example scripts: `live_trading.py` skips non-kline frames and validates the
symbol/interval; `backtest.py` and `multi_timeframe.py` report clear errors
for malformed CSV input.
## [0.1.4] - 2026-05-21
### Added
- GitHub Release runs now attach every built artefact (wheels, sdist, native
Node binaries, npm-pack tarballs, cargo `.crate` files) to the tag's
release page.
## [0.1.3] - 2026-05-21
### Fixed
- npm package ships the napi-generated loader and is built with `--platform`
so the per-platform binary is resolved correctly.
## [0.1.2] - 2026-05-21
### Fixed
- Release pipeline: per-platform idempotent npm publishing with a spam-filter
retry, and committed `npm/<platform>/` package templates.
## [0.1.1] - 2026-05-21
### Fixed
- Node publish step and coordinated version bump across all bindings.
## [0.1.0] - 2026-05-21
### Added
- Initial release: a streaming-first technical-analysis library with 25
indicators (SMA, EMA, WMA, DEMA, TEMA, HMA, KAMA, RSI, MACD, ROC, Stochastic,
CCI, Williams %R, ADX, MFI, TRIX, Aroon, Awesome Oscillator, Bollinger Bands,
ATR, Keltner Channels, Donchian Channels, Parabolic SAR, OBV, VWAP).
- Rust core (`wickra-core`), umbrella crate (`wickra`), and a data layer
(`wickra-data`) with a CSV reader, tick aggregator, resampler, and an
optional Binance live feed.
- Bindings for Python, Node.js, and WebAssembly.
