Fix tag search prefix matching (exact match)

[fmaass]

Problem

Searching tag:auto also returns documents tagged auto-import because TagUtil.findByName uses startsWith matching.

Upstream: sismics/docs#662

Fix

Change TagUtil.findByName to use equals instead of startsWith on lowercased tag names.

Reverted in v2.2.0 — prefix matching is more user-friendly for discovery. Will reintroduce as a configurable option (exact vs prefix) in a future release.
