- In the project (top-level) readme file, kept one language's code example and moved all others out to language-specific readme files.
...
- Added a readme file for each programming language implementation (port) if it didn't already have one, mostly by copying the project readme text, and then added/edited a couple of feature points.

Generalized the Java API to accept CharSequence instead of String, which can be helpful if the input is a temporary StringBuilder. This is possible because almost all functions read characters and convert them to another representation in a new buffer instead of storing the input string immutably.

Added string length limit and integer value range assertions to QrSegmentAdvanced.computeCharacterModes(). This fixes int32 overflow for ridiculously long input strings (somewhere around 2^23 characters), which are impossible to put in a QR Code anyway.

Moved QrCodeGeneratorDemo.java out of the package because it's an informal demo and not a core library feature; this also simplifies the Maven build process.

Updated Java POM configuration to exclude QrCodeGeneratorDemo because it's not core library functionality.

Added new public functions QrSegment.{isNumeric(),isAlphanumeric()} and privatized the regexes in {Java, TypeScript, Python}, because the regexes are awkward compared to a clean abstraction.

Demoted ReedSolomonGenerator from a class to a set of functions, and changed some names and comments, in all languages except C. This reduces code verbosity but doesn't change public APIs or visible behavior. The code organization is similar to the finder-like-pattern-detector feature.

Inlined the Java-version finder-like pattern detector into the penalty score calculation logic in a non-trivial way, keeping behavior identical but reducing {declarations, computations, comments, explanations}.

Renamed a local variable in all language versions (although the Java version has different logic).

Replaced the finder-like pattern detection algorithm with a more sophisticated and accurate one, including documentation comments, only for the Java version of the library. This fixes nearly all the false negatives/positives in the previous implementation.

Reordered calls to applyMask()/drawFormatBits() for conceptual clarity, without changing output (because masks don't affect format bits), in all language versions.
