fix(parser): preserve legal comments with @preserve/@license when preceded by other annotations (#15929) Legal comments like `/* @foo @preserve */` were not being preserved when legal comment output was enabled. The parser only checked if the first `@` annotation matched known patterns, missing `@preserve`/`@license` later in the comment. ## Changes **Parser (`oxc_parser/src/lexer/trivia_builder.rs`)** - Add fallback check using `contains_license_or_preserve_comment` after `__PURE__`/`__NO_SIDE_EFFECTS__` checks - Ensures `@license`/`@preserve` detected anywhere in comment text ## Example ```javascript // Before: Legal comment not detected by parser /* @foo @preserve */ function foo() {} // Parser classifies as: CommentContent::None ❌ // After: Legal comment correctly detected /* @foo @preserve */ function foo() {} // Parser classifies as: CommentContent::Legal ✅ ``` Related: https://github.com/rolldown/rolldown/issues/7160  <details> <summary>Original prompt</summary> > `/* @foo @preserve */` should be preserved when legal comment output is enabled even if comment output is disabled. https://github.com/rolldown/rolldown/issues/7160 is related </details>  --- ✨ Let Copilot coding agent [set things up for you](https://github.com/oxc-project/oxc/issues/new?title=✨+Set+up+Copilot+instructions&body=Configure%20instructions%20for%20this%20repository%20as%20documented%20in%20%5BBest%20practices%20for%20Copilot%20coding%20agent%20in%20your%20repository%5D%28https://gh.io/copilot-coding-agent-tips%29%2E%0A%0A%3COnboard%20this%20repo%3E&assignees=copilot) — coding agent works faster and does higher quality work when set up for your repo.
