StandardConfig refactoring (DONE)

All config structs now embed StandardConfig via #[serde(flatten)].

Cache cleanup

• Remove old DB cache code: CacheEntry, OutputEntry, get_entry, has_cache_entry, get_cached_input_checksum, CACHE_TABLE. These are legacy from the pre-descriptor system. has_cache_entry (used in status display to distinguish “stale” vs “new”) should use the descriptor system instead. ~80 lines of dead code.

• Remove cache_key() method from Product. Only used by has_cache_entry and remove_stale. Once has_cache_entry is migrated to descriptors, it may become fully unused.

• Split db.redb: the configs table (CONFIGS_TABLE) is still in the same DB as the now-unused cache table. Give configs its own file (configs.redb), then delete db.redb entirely.

Cache correctness

• Implement output_depends_on_input_name flag. Documented in docs/src/cache.md but not implemented. Needed for processors that embed the input filename in their output (e.g., a // Generated from foo.c header). Without it, renaming such a file would produce a cache hit with stale content.

• Write a test for identical content processed by different processors. Verify two different processors processing the same file get separate cache entries (the processor name is in the descriptor key).

Code consolidation

• Inline single-use names constants. 20+ constants in processors::names are used in exactly one place each (their processor’s new() call). Inline them as string literals.

• Clean processor_configs.rs. Still 2,100+ lines. Check for:

  • ClangTidyConfig is nearly identical to StandardConfig — could it become a type alias?
  • Unused default_* helper functions left over from cppcheck removal.
  • Other config structs that are structurally identical to StandardConfig.

Documentation

• Add docs/src/processors/creator.md — per-processor documentation for the Creator processor, like the other processor docs.

Housekeeping

• Remove the tar lockfile entries. The crate was added and removed, but Cargo.lock may still reference it.

• Commit everything. There is a large amount of uncommitted work spanning:

  • HasScanConfig trait elimination
  • SimpleGenerator (14 generators collapsed to data-driven)
  • Creator processor (new processor type with multi-dir caching)
  • Cache redesign (descriptor-based, content-addressed keys, no DB for cache data)
  • Checksum cache centralization (moved mtime logic to checksum.rs with own DB)
  • MassGenerator → Creator type rename
  • ProcessorType enum with strum iteration
  • processors types CLI command
  • --no-mtime-cache CLI flag
  • Mandatory supports_batch on all processors
  • Checker consolidation (5 checkers → SimpleChecker entries)
  • Removed unused dirs crate
  • New documentation: cache.md, checksum-cache.md, processor-types.md
