docs(es/minifier): Document the unshadowed Math assumption Adds an exec test covering negative folded results in member-object position, which the fixer already parenthesizes.

feat(es/minifier): Evaluate Math.floor, Math.ceil, Math.round and Math.sqrt Extends eval_as_number with four more Math methods, guarded so a call is only replaced when the resulting literal is strictly shorter than the call itself. Math.round is implemented against the ECMA-262 rule (ties round towards +Infinity) rather than f64::round, which rounds ties away from zero and disagrees on every negative half.

fix(react-compiler): preserve TypeScript function overload signatures (#12115) **Description:** Preserve whether a function originally had an implementation body when converting through the React Compiler AST. React Compiler's `FunctionDeclaration` representation always contains a block body. The SWC converter therefore synthesized an empty block for TypeScript overload signatures, but the reverse conversion did not restore the original missing body. The TypeScript transform then treated every overload signature as a concrete runtime function, producing duplicate default exports. This change records the original body presence in `PreservedAst` and restores `None` for overload signatures. The integration test forces React Compiler output with `compilationMode: "all"` and verifies that the overloads remain bodyless while the implementation retains its body. Validation: - `cargo fmt --all` - `cargo test -p swc_ecma_react_compiler` - `cargo clippy --all --all-targets -- -D warnings` **BREAKING CHANGE:** None. **Related issue (if exists):** https://github.com/web-infra-dev/rspack/issues/15158

fix(es/minifier): bound arguments parameter injection (#12053) **Description:** Replacing an `arguments` access with a named parameter can require injecting every missing parameter up to that index. A large index can therefore generate an unbounded number of parameters and substantially increase output size. This PR follows Terser's fixed bound: an access is replaced only when it reuses an existing parameter or requires injecting at most five additional parameters. Larger gaps remain as `arguments` accesses, with fixture coverage for the five/six boundary. **Related issue (if exists):** - Close: #12108 --- - #12043 - #12047 - #12050 - #12048 - #12051 - #12052 - **#12053** (current) - #12054 - #12055 - #12056 - #12057 - #12058 - #12049 - #12059 - #12060
