chore(release): v1.0.0 stable release (#679)

* docs: apply mechanical doc-review fixes (#677)

* docs: fix 74 broken links, 5 anchors, 4 version refs

Phase 1 (Must-Fix): resolve wrong relative paths in docs/advanced/
README*.md and related advanced/ files; fix CHANGELOG CONTRIBUTING/
LICENSE links to repo root; correct BUILD_GUIDE, API_REFERENCE, and
PERFORMANCE cross-refs; mark non-existent targets (DESIGN_IMPROVEMENTS,
PLATFORM_BUILD_GUIDE, LOG_LEVEL_UNIFICATION_PLAN, Korean translations,
integration sub-guides) with TODO markers. Fix formatter_macros anchor
slug in API_REFERENCE, PATTERNS section-number anchors in FAQ files,
and mark FAQ TOC drift in docs/guides/FAQ.md and docs/advanced/
PERFORMANCE.kr.md.

Phase 2 (Should-Fix): align CONTRIBUTING.md and PROJECT_STRUCTURE*
compiler baseline with README.md (GCC 13+/Clang 17+/MSVC 2022+).
Downgrade docs/performance/BASELINE.md status from Released to Draft
since all benchmark cells remain TBD; add explicit TODO marker on the
primary TBD table.

* docs: add post-fix re-validation report

* docs(version): update documentation, CHANGELOG, and version for v1.0.0 (#678)

* chore(version): bump version to 1.0.0

Update project version from 0.3.1 to 1.0.0 in CMakeLists.txt
and vcpkg.json for the stable v1.0 release.

* docs(changelog): add v1.0.0 release section

Summarize all changes since 0.3.1: queue consolidation, Result<T>
migration, API freeze, CMake rename, performance improvements,
and comprehensive documentation overhaul.

* docs(version): update version refs and coverage claim across all docs

Update FetchContent GIT_TAG from v0.3.0 to v1.0.0 in README, guides,
and migration docs. Correct code coverage claim from 72% to 49%
(verified via Codecov). Update doc frontmatter versions to 1.0.0.
