v0.5.0

What's new in 0.5.0

Features

• trend JSON output — the trend tool gains a format="table"|"json" parameter, mirroring query.
• dbecho --version — print the installed version.
• dbecho --check — validate the config and ping every configured database, printing an [OK]/[FAIL] <name> line per database and exiting non-zero if any is unreachable. Drops straight into a CI or healthcheck script.
• find tool (first published release) — locate tables and columns by name substring across all configured databases at once.

Hardening

• publish.yml now fails the publish if the release tag and pyproject version disagree (PyPI versions are immutable, so a mismatch would burn the number permanently).

Full test suite: 224 tests, all passing. No Postgres required (mocked connections).
