Release 0.6.2

Fixes

N/A — release PR.

Changes

• Bumped tygr and tygr-derive to 0.6.2 (both Cargo.tomls and both Cargo.locks).
• Added the [0.6.2] CHANGELOG entry, bundling Reword StringEq!/StringEqCI! partial-match Display to a possessive #45 (possessive Display wording) and Quote and escape GrammarFrom's matched text in Display #47 (GrammarFrom quoting).

Test Plan

• CI (fmt, clippy, test, doc across default/no-default-features/all-features, plus version-consistency).

Notes

• Patch release: both bundled changes are Display-only wording/formatting fixes, no signature changes.
