[1.0.0] - 2026-05-19

Added

• Initial release.
• decode(s) — parse an Alpha-5 or plain numeric designator string into its
  canonical integer form. Accepts numeric strings of any length (for JSON-
  coerce compatibility) but rejects values outside the 0–339,999 range.
• encode(n) — encode an integer (0–339,999) into a 5-character designator
  string, using the Alpha-5 letter prefix for values 100,000 and above.
  Rejects every non-integer numeric kind (BigInt, boolean, string, null,
  undefined, NaN, Infinity, floats).
• Hand-written TypeScript declarations.
• Test suite covering every example in the Space-Track Alpha-5 documentation,
  the full A=10..Z=33 letter table, both I/O-skip boundaries in both
  directions, and a round-trip property check sampling the full 0–339,999
  range.
