10887: fixed failing bats test
10876: go/store/nbs: Fix a rare race condition whould could cause GC and some concurrent readers or writers to deadlock.
If a GC was started immediately after another GC finished, a session which was waiting on the first GC completion could get stuck waiting for the second GC to complete instead. But the second GC itself was going to block on that session finishing whatever work it was doing.
Added tracking for the gcCycleCounter which reflects the actual GC operation which any individual call into the NomsBlockStore actually needs to block on.
10875: Add swappable identifier validation function
Adds a function variable that Doltgres can override to change identifier validation logic.
Related to dolthub/doltgresql#2580
10873: Fix panic when branch tracking has no merge ref
Fixes a nil pointer panic in DOLT_PULL when a branch has a remote recorded in its tracking configuration but no merge ref set.
Fix #10839

10820: go: derive internal cache sizes from GOMEMLIMIT

Solves #10821
Adds a memlimit package that reads standard Go GOMEMLIMIT and proportionally sizes Dolt's three largest caches (node cache, memtable, decoded chunks)
When GOMEMLIMIT is unset, all defaults preserved exactly — zero behavior change
Replaces the per-cache env var approach from #10815/#10816 with a single standard knob

GOMEMLIMIT=512MiB dolt sql-server

Cache	Default	At GOMEMLIMIT=512MiB
Prolly node cache	256 MiB	~120 MiB
Memtable write buffer	256 MiB	~120 MiB
Decoded chunks cache	32 MiB	~15 MiB
Budget partitioning: 50% usable (50% GC reserve), then 47/47/6 across caches — matching the ratio of the original hardcoded defaults (256:256:32 MiB). Minimums prevent pathologically small caches. Maximum caps ensure caches never exceed current defaults, even with high GOMEMLIMIT — we can loosen these later if needed.

New: go/libraries/doltcore/memlimit/ — budget calculator with 8 unit tests
Modified: go/store/prolly/tree/node_store.go — lazy sync.Once init via memlimit
Modified: go/store/types/value_store.go — decoded chunks from memlimit
Modified: go/libraries/doltcore/dbfactory/ — all 8 factory impls call memlimit.MemtableSize() directly
Modified: go/cmd/dolt/dolt.go — memlimit.Init() in runMain()

8 unit tests: defaults, zero, 512 MiB, 128 MiB, 32 MiB (minimums), 4 GiB (capped at defaults), accessors
store/prolly/tree, store/types, libraries/doltcore/dbfactory, store/prolly test suites pass

3510: Ignore unique key errors when inserting into fulltext position table
fixes #10882
Ignore unique key errors when inserting into fulltext index.Position table (similar to how unique key errors are ignored for index.DocCount).
We should consider using a non-unique index for index.Position and index.DocCount or restructuring how we're writing to these tables if we're always going to be ignoring unique key errors.
3508: go.mod: Bump go-icu-regex.
3505: trim analyzer rules for simple selects
This PR adds a fast analysis pass for queries of the form SELECT ... FROM ... WHERE ....
The idea is that simple select queries (no subqueries) can avoid many (recursive) analyzer rules like applying triggers and foreign keys.
