Publish v0.2.0

[carpentry-agent]

Last release: 0.1.0, cut 2026-06-24.

This repo has no CHANGELOG; summary from the commit log since 0.1.0:

• Prepared statement API — prepare, exec-prepared, reset-stmt, finalize-stmt (Add prepared statement API #5).
• Memory-safety fixes in the C helper layer (Fix memory-safety bugs in the C helper layer #9).
• Housekeeping: match instead of Result.unsafe-from-success in tests, doc-string hygiene, removed banner/separator comments.

Proposed bump

minor → 0.2.0 — the prepared-statement API is a new backward-compatible addition; the memory-safety work is a bug fix.

(Consider adding a CHANGELOG.md — most carpentry-org libs keep one.)
