v0.3.0 — LQColligo (FluentQuery rebrand)

First release under the LQColligo name. This completes the rebrand of
the former FluentQuery library (unit/namespace and public type names) and
ships the finished tests, docs and packaging metadata.

⚠️ Breaking

Pre-1.0 breaking change — the namespace, unit and public types were renamed:

• uses FluentQuery → uses LQColligo (+ LQColligo.Collections, etc.)
• IFluentEnumerable<T> → ILQColligoEnumerable<T>
• IFluentQueryable<T> → ILQColligoQueryable<T>
• TFluentArray/TFluentList/TFluentString → TLQColligoArray/TLQColligoList/TLQColligoString

Highlights

• Full brand/namespace/type rebrand FluentQuery -> LQColligo.
• Test harness renamed (PTestLQColligo* / UTestLQColligo.*) and search paths fixed.
• Docs migrated (docs/lqcolligo), Docusaurus baseUrl /LQ-Colligo/, "Inspired by LINQ" note added.
• SBOM lq-colligo-0.3.0.cdx.json; pubpascal.json bumped to 0.3.0.
• AUDIT.md retained as a dated pre-rebrand historical snapshot.

Validation

• 6 Delphi test projects compile (dcc32, Delphi 23), EXITCODE=0.
• In-memory suites: 292 tests, 0 failures.
• Docusaurus build passes with onBrokenLinks: 'throw'.
