SemTS v1.0.0

Initial publication of the Semantic Timestamp Specification (SemTS) and reference implementations.

Highlights

Final release encodes as .999 ms within the same second for clear ordering.
Pre-release mapping:
- alpha: 100–199
- beta: 200–299
- rc: 300–399
- unknown tags: 900–999 (MUST use base 900 + N)
Pre-release number MUST be 0–99 (negative values not allowed).
UTC is used for date and time components.
Tools MUST set last-modified; tools MAY also set creation time (where supported).

Decoding Guide and Compliance Test Cases are included in the README.
Security considerations: timestamps are forgeable—use alongside signatures/checksums.
