feat!: upgrade to official rules_rust 0.65.0

BREAKING CHANGE: Remove git_override dependency and upgrade to official rules_rust 0.65.0

This major milestone transitions from custom patches to official upstream support for
WebAssembly Component Model development.

Changes:
- Upgrade rules_rust from 0.62.0 + git_override to official 0.65.0
- Remove git_override dependency that blocked BCR publication
- Update rules_cc to 0.2.4 (eliminates version warnings)
- Update installation documentation for official rules_rust integration
- Mark BCR publication as ready (issue #7 resolved)
- Prepare CHANGELOG for 2.0.0 release

Migration required:
Users must update MODULE.bazel to remove git_override and use:
bazel_dep(name = "rules_rust", version = "0.65.0")

Benefits:
- Official WASI Preview 2 support included by default
- BCR publication now unblocked
- Enhanced stability with official upstream support
- Simplified installation without custom patches

Resolves: #7
