Summary

Release compilation-scoped plugin maps when a watch rebuild replaces the preceding compilation.

The native CSS, SRI, and Rsdoctor plugins retain several maps keyed by monotonically increasing CompilationId; the corresponding entries were not fully removed from clear_cache(old_id). Repeated rebuilds can therefore retain hooks, integrity/context state, or diagnostic/module metadata for every prior generation.

This change uses the existing plugin lifecycle hook and only removes state for the completed compilation:

• CSS: COMPILATION_HOOKS_MAP;
• SRI: COMPILATION_INTEGRITY_MAP and COMPILATION_CONTEXT_MAP;
• Rsdoctor: module, entrypoint, JSON-size, and active-export-usage maps alongside the existing hook-map cleanup.

No public API, option, or compilation behavior changes.

Validation

• Source audit/regression confirms every compilation-keyed map in these three plugins has a matching removal (8/8 entries cleared; seven were previously missing).
• An optimized native-binding watch smoke enables native CSS, SRI, Rsdoctor, and HMR, performs repeated edits, and verifies emitted updates and diagnostics remain correct.
• rustfmt --edition 2024 --check crates/rspack_plugin_css/src/plugin/impl_plugin_for_css_plugin.rs crates/rspack_plugin_sri/src/lib.rs crates/rspack_plugin_rsdoctor/src/plugin.rs and git diff --check pass.

This is independent of the ModuleGraphConnectionWrapper lifecycle fix in #14772.
