web: rename a database from its settings page

A database's name lives in two places — the metadata row and the on-disk
store directory its path names — so a rename has to move both. The order
is creation's: the row first, where a name already taken is refused by the
unique index before anything on disk changes, then the store, then the
handle the remotesapi memoized under the old path. A store that will not
move rolls the row back, so the two halves never disagree about where a
database lives; only a failed rollback is escalated to a human, because
it is the one outcome no later request can repair.

storage.MoveStore is one os.Rename behind the containment guard DeleteStore
already used, extracted here as containedPath. It refuses an occupied
destination outright: os.Rename over an empty directory would succeed and
swallow it.

No redirect is left behind — the old address simply stops resolving, as on
git.sr.ht — so an existing clone needs its remote replaced, and a companion
of a git repository is re-provisioned under its old name by the next push
to that repository. The README's quickstart now says both.

doltsrht: serve /mcp on the web listener

build: pure-Go (CGO_ENABLED=0) build via a klauspost-backed gozstd shim

dolthub/dolt/go pulls in two hard cgo dependencies — go-icu-regex (SQL
REGEXP) and gozstd (NBS zstd compression) — which forced a C toolchain +
ICU headers on every build. Both are now avoided so the default build is
pure Go and statically linkable:

- ICU: build with `-tags gms_pure_go`, selecting go-mysql-server's stdlib
  regexp fallback. Safe because this service never runs the SQL engine
  (it serves bare NBS stores and browses read-only), so it never
  evaluates SQL REGEXP.
- zstd: `replace github.com/dolthub/gozstd => ./third_party/gozstd-purego`,
  a pure-Go drop-in over klauspost/compress/zstd (already in the graph).
  It reproduces the nine gozstd symbols dolt references. dolt is
  unmodified.

dolt uses gozstd only in its NBS archive subsystem; this binary hits only
the decompress side at runtime (archive dictionary TRAINING is gc/
archive-writer code we never run — the shim implements it over klauspost
but panics on the trainer errors that only that off-path use could
trigger). zstd frames and dictionaries are standard-format, so
libzstd-authored archives decode correctly; the shim's tests prove this
by decoding plain and dictionary-compressed frames produced by the zstd
CLI (libzstd).

The Makefile now defaults to CGO_ENABLED=0 + -tags gms_pure_go (override
with `make CGO_ENABLED=1 GO_TAGS=` for the cgo variant). Verified:
CGO_ENABLED=0 build of ./..., all unit tests, the real-dolt-CLI
integration + spike suites, and the shim's libzstd-interop tests, all
green with no cgo.

rename module to sourcecraft.dev/bigbes/sr-ht-dolt; depend on sourcecraft sr-ht-core

build: source core-go from the instance fork

Replace git.sr.ht/~sircmpwn/core-go with git.srht.bigb.es/~bigbes/core-go
at c2c2f38 (upstream fdb3662 + newer upstream commits + the phoebe-lab S3
UnsignedPayload patch) - the code production actually runs. Requires
GOPRIVATE=git.srht.bigb.es to fetch. Full suite re-verified including the
remotesapi integration scenarios.

foundation: module, core domain, schema, spike-verified dolt interop

Phase 0 foundation for dolt.sr.ht (pure-Go Dolt hosting for SourceHut).

Dependency pins:
- core-go v0.0.0-20260520082310-fdb3662452dc: the production instance's
  submodule commit (fdb3662); must never be upgraded so token/config/crypto
  behavior matches the rest of the instance.
- dolthub/dolt/go v0.40.5-0.20260626152440-45335d44ad79: pseudo-version at the
  commit tagged v2.1.10 (45335d44), matching the installed dolt CLI. The /go
  submodule's latest tag (v0.40.4, 2021) does not interop with a modern CLI;
  matching the CLI commit guarantees a common NBS format (Format_DOLT) and
  remotesapi proto.
- gopkg.in/go-jose/go-jose.v2 v2.6.3: same JOSE version dolt's creds package
  signs EdDSA keypair JWTs with, avoiding a duplicate JOSE lib.
- grpc v1.79.3, logrus v1.8.3, lib/pq v1.10.9, chi/v5 v5.3.1, brant v0.5.1.

Contents:
- core/ pure domain: models, ValidateName/ParseRepoPath, the access matrix
  (Allowed + NotFoundForPrivate), full table-driven tests.
- schema.sql + migrations/0001_initial.sql (brant format).
- config.example.ini, contrib/dolt.sr.ht.conf (nginx), Makefile, scss/main.scss,
  static/logo.svg, README, .gitignore.
- internal/smoke: throwaway import-and-build check (deleted in Phase 3).

Spike (storage/spike_test.go, tag `spike`): bare NBS store via WriteEmptyRepo,
served by remotesrv on an ephemeral single port, round-tripped through the real
dolt CLI v2.1.10 (clone -> insert -> commit -> push -> re-clone -> verify rows).
Green, no version juggling needed beyond selecting the v2.1.10 commit. FS must
be rooted at the repos dir (LocalFilesysWithWorkingDir) so sealed chunk-URL
prefixes are clean relatives.

Build note: dolt pulls go-icu-regex (CGO), which needs ICU4C headers; on this
Mac set CGO_CPPFLAGS/CGO_LDFLAGS to icu4c@78 (documented in README).
