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.

Stand up executus/tools — the generic, host-agnostic tool library — and prove
the full pattern end to end:
- tools/tools.go: Register(reg) adds the always-available zero-dependency tools
(currently `think`). A light host calls it and is immediately useful; backed
tools (web/store/meta groups) will register via grouped registrars with
nil-safe Deps as they land.
- tools/think.go: the `think` tool moved from mort (imports only executus/tool).
- tools/integration_test.go: end-to-end proof that the executor runs an agent
which CALLS a registered tool — the fake model emits a `think` tool call, the
executor dispatches it through the registry, the model finalises, and the step
instrumentation captures the `think` step. Exercises the full tool-dispatch
loop through run.Executor.
Stacked on phase-2-run-kernel (P3 needs run.Executor). Remaining P3: the
meta/web/net/store/compose groups + their Deps + default backends (splitting
mort's default.go grab-bag).
