v0.0.3

Changelog for cmdutils@v0.0.3

This release focuses on the addition of `text` subnet and expansion of `image` subnet.

---

text subnet - new utils

• count counts lines, words, characters, and bytes of a file or stdin
  (wc-style, with -w/-l/-m/-c flags)
• case converts text between upper, lower, title, snake, kebab, camel,
  pascal, and constant letter cases
• replace replaces all occurrences of a string, with in-place (-i) and
  output-file (-o) modes
• base64 encodes and decodes base64 data from a file or stdin
• checksum computes md5, sha256, or sha512 hashes of a file or stdin

image subnet - new utils

• crop crops an image to a WxH+X+Y region with bounds validation
• rotate rotates an image clockwise in 90° steps
• grayscale converts an image to grayscale (Rec. 601 luma)
• watermark overlays semi-transparent text on an image using a system font,
  a bundled fallback font, or a custom --font, with --color, --opacity,
  --position, and --size
• watermark falls back to a bundled Roboto font when no system font is
  installed, so it works on font-less systems (e.g. minimal CI containers)
• strip removes all embedded metadata (EXIF, comments) from an image

image subnet - batch & glob processing

• All image utils now accept glob patterns (e.g. *.png, photos/*.jpg)

• Multiple matches are processed in parallel with bounded concurrency and
  per-file error reporting

  TL;DR: v0.0.3 introduces the text subnet, adds five new image utils
  (crop, rotate, grayscale, watermark, strip), and brings glob
  patterns with parallel processing to the entire image subnet
