Remove Node engine upper bound

[joesobo]

Summary

• removed the Node <23 upper bound from package manifests while keeping the published minimum at >=20
• updated docs to distinguish published Node 20+ support from the repo/CI pinned Node 22 runtime
• added a changeset for the published packages whose engine metadata changes
• patched tree-sitter@0.25.0 so its native binding builds with C++20 instead of C++17
• documented the patch in patches/README.md as a temporary backport of the upstream fix

Why

Node 26 failed during dependency installation because tree-sitter@0.25.0 compiled its native binding as C++17, while Node 26's V8 headers require C++20. C++20 is just the newer C++ language standard the compiler must use for that native addon.

npm view tree-sitter version versions --json shows 0.25.0 is still the latest published tree-sitter runtime, so there is no newer runtime package to upgrade to for this failure. The practical fix is a small pnpm patch to binding.gyp.

The equivalent upstream fix was merged in tree-sitter/node-tree-sitter#258, but it has not reached npm because the 0.25.1 publish is still blocked by tree-sitter/node-tree-sitter#276. This local patch should be removed once tree-sitter publishes a release with the Node 23+ C++20 build fix. Follow-up Trello card: https://trello.com/c/Myxab48H

CI remains pinned to Node 22.22.0; this PR broadens the published package engine range and fixes the known newer-Node install blocker without redesigning CI.

Before patch:

• host: Poleskis-Mac-mini.local
• node: v26.0.0
• pnpm: 10.32.0
• pnpm install --frozen-lockfile failed while building tree-sitter@0.25.0

/Users/poleski/Library/Caches/node-gyp/26.0.0/include/node/v8config.h:13:2:
error: "C++20 or later required."

After patch:

• host: Poleskis-Mac-mini.local
• node: v26.0.0
• pnpm: 10.32.0
• pnpm install --frozen-lockfile passed
• pnpm --filter @codegraphy-dev/core typecheck passed
• pnpm --filter @codegraphy-dev/mcp test passed: 1 file, 13 tests

Earlier supported baseline:

• node: v22.22.2
• pnpm install --frozen-lockfile passed
• pnpm run typecheck passed
• pnpm run lint passed, with 32 generated-acceptance spacing warnings
• pnpm --filter @codegraphy-dev/mcp test passed
• pnpm run mutate -- packages/mcp/src/mcp/server.ts passed: 5 mutants, 100% mutation score

Local Verification

• pnpm install --frozen-lockfile passed on Node v22.22.0
• pre-commit pnpm run typecheck passed for the engine/patch commit
• pre-commit pnpm run typecheck passed for the final evidence commit
• pre-commit pnpm run typecheck passed for the patch documentation commit

GitHub CI

GitHub CI passed on the previous latest commit before the final docs-only evidence correction. The final commit only updates this handoff note.
