Grow executus/tools into a real generic tool library:
- Register(reg): the always-available, zero-config tools — think, now (UTC
unless a CurrentTimeProvider is wired), cite (inert unless a CitationStorage
is wired). All nil-safe; a light host calls Register and is useful.
- RegisterMeta(reg, MetaDeps): the LLM-backed meta tools — classify,
extract_entities, summarize — over the llmmeta helper. Budget defaults to the
shipped in-memory per-run cap; Files optional; caps default.
- Seams moved (interface/type-only, no host coupling): research_providers.go
(CurrentTimeProvider/CitationStorage/SearchBudget/PageExtractor/PDFFetcher/…)
and file_storage.go (FileStorage + FileDomainMeta). Plus the in-memory budget
default (research_defaults.go) and scope_validate.go.
calculate deferred (drags github.com/Krognol/go-wolfram + a module-path replace
— not worth it in the lean core for one tool). Core go.sum still free of
gorm/redis/discordgo/sqlite/wolfram.
