fix(build): stop bundling the better-sqlite3 stub at runtime (#11343 )

next.config.mjs aliased `better-sqlite3` to its build-time stub unconditionally, recording the premise that "runtime still uses the real package via serverExternalPackages". That premise does not hold: a Turbopack resolveAlias rewrites the request BEFORE the externals check runs, so the request stopped matching the serverExternalPackages entry and the stub was baked into the shipped bundle. Every artifact built from the release tip then answered HTTP 500 on every route -- the sync driver failed with "r(...) is not a constructor" (the minified stub export), fell through node:sqlite and sql.js, and the instrumentation hook aborted at boot. Same failure shape as #6344, one alias above it in the same object, so it gets the same treatment: a shared flag helper makes the alias opt-in via OMNIROUTE_BETTER_SQLITE3_STUB=1, and a default build externalizes the real native addon. Nobody sets the flag today; it exists for a build host that genuinely hits the SIGABRT worker teardown from #10060, and such a build is not shippable -- which the helper and the stub header now say explicitly instead of describing the stub as a harmless build-only stand-in. Closes #11343

 ### 🐛 Bug Fixes

+- **fix(build):** every route no longer answers HTTP 500 on artifacts built from the release tip ([#11343](https://github.com/diegosouzapw/OmniRoute/issues/11343)) — `next.config.mjs` aliased `better-sqlite3` to its build-time stub **unconditionally**, on the premise that `serverExternalPackages` still won at runtime. It does not: a Turbopack `resolveAlias` rewrites the request *before* the externals check, so the request stopped matching the `better-sqlite3` external entry and the stub was baked into the shipped bundle. The sync driver then failed with `r(...) is not a constructor`, fell through `node:sqlite` and sql.js, and the instrumentation hook aborted at boot. Same failure shape as [#6344](https://github.com/diegosouzapw/OmniRoute/issues/6344), so it gets the same treatment: the alias is opt-in via `OMNIROUTE_BETTER_SQLITE3_STUB=1` through the shared `scripts/build/better-sqlite3-stub-flag.mjs` helper — set it only on a build host that actually hits the SIGABRT build-worker teardown ([#10060](https://github.com/diegosouzapw/OmniRoute/issues/10060)); default builds externalize the real native addon. Regression guards: `tests/unit/better-sqlite3-stub-alias-11343.test.mjs` (5) and the env matrix in `tests/unit/next-config.test.ts`.
 - **security(search)**: block SSRF via `/v1/search` `provider_options.baseUrl` for the Firecrawl search provider — the client-controlled override is now validated as a public URL before it is used to build the server-side fetch target, so a caller with a valid API key can no longer redirect search requests at loopback, RFC1918, or cloud-metadata hosts — thanks @zmf963
 - **providers**: honor `PATCH /api/providers/[id]` so `omniroute providers rotate` stops 405ing (the OpenAPI spec and CLI already use PATCH) (PR #10366)
 - **cli**: route provider test commands through configured connection test endpoints (#10570)
