docs(server): name HTTP_KEEP_ALIVE_TIMEOUT_MS as an httpConfig variable

The keep-alive change moved HTTP_KEEP_ALIVE_TIMEOUT_MS onto the httpConfig
token, but the app-config README still listed only TRUST_PROXY and
HSTS_INCLUDE_SUBDOMAINS for it and left the variable out of the
boot-stable list. Also drops the dashes from two lines the recent
scheduling and entity changes rewrote.

 - **`src/bootstrap.ts` — `buildApp()`** is the single builder for production and the test harness. Everything on the raw Express instance (global middleware, uploads, discovery metadata, statics, the named `jsonParser`/`urlencodedParser` wrappers) is registered **before `app.init()`**, because Nest throws `NotFoundException` on unmatched routes and nothing after init is reachable. The wrappers exempt `/mcp` so the MCP SDK reads the raw stream — **never `@Body()` a `/mcp` route**. Don't add routes to that pre-init shell; it bypasses every global guard, interceptor and filter.
 - **Realtime**: `/ws` is a Nest gateway in `src/nest/realtime/`. Inject `RealtimeService`; `src/websocket.ts` is a re-export stub for old call sites. Trip mutations forward `X-Socket-Id` so the originating client doesn't echo its own change.
 - **MCP**: `src/nest-mcp/` is the decorator/registry layer (`@McpController`/`@Tool`/`@Resource`/`@Prompt`; see its `README.md`); tools live in `<domain>.mcp.ts` files beside each module; the HTTP transport is `src/nest/mcp-transport/`; `src/mcp/` holds process-wide state only (scopes, session manager, boot policy). Every tool invocation writes an audit row through the registry's `onInvoke` seam. MCP tools are adapters over the same services and permission checks as REST — a change on one side lands on the other in the same change.
-- **Scheduling**: `src/nest/scheduling/` (`CronRegistrarService`) is the one way to schedule a cron. Jobs are `*.job.ts` providers in their owning domain. The registrar refuses to schedule under `NODE_ENV=test` (an integration test pins it). **Never use a `@Cron` decorator** — it bypasses that gate. Every tick first takes the job's row in `scheduler_leases` (`SchedulerLeasesRepository.acquire` in one `UnitOfWork` transaction, where a conditional UPDATE decides the race), renews it while it runs and keeps it for a short settle window afterwards, so two processes on one database never run the same tick; a job needs nothing of its own for this. Claims on individual rows (the reminder jobs' `claimReminder`) stay where they are: the lease decides who runs a tick, the claim what a tick may send.

Claims on individual rows (the reminder jobs' `claimReminder`) stay where they are: the lease decides who runs a tick, the claim what a tick may send.
 - **Plugins** (`src/nest/plugins/`): the child-process runtime (`supervisor/`, `runtime/plugin-host-entry.ts`, `protocol/envelope.ts`) is **intentionally not Nest** — it is the security boundary. `host/rpc-host.ts` registers an RPC method at spawn only if the plugin holds the unlocking permission (registration = authorization). Install-time gates live in `install/`; the manifest's `trek` version range fails closed, and `TREK_PLUGINS_IGNORE_TREK_RANGE` downgrades that to a warning. The protocol tables in `protocol/envelope.ts` (+ `src/plugin-event-sink.ts`) are **generated** into `plugin-sdk/` and `shared/` — run `gen:plugin-facts` after touching them and commit the output. `runtime/egress-policy.ts` is a hand-kept mirror guarded by a parity test in `plugin-sdk/`; change both sides together.
 - **Storage**: `src/nest/storage/` is the upload driver abstraction (local / S3 / mirror behind one interface, with an admin surface and a usage job). Domain services never touch the filesystem or the S3 SDK directly. Where the data lives (`data/`, `uploads/`, backups, logs, key files, the DB file) is resolved in one place, `src/app-config/data-paths.ts`; Nest classes inject `DataPathsService`, and nothing anchors a data path on its own `__dirname` or on `process.cwd()`.
 - **DB** (`src/db/`): `better-sqlite3`, WAL, FK on. `database.ts` only holds the connection and applies pragmas. It does not build a schema, and importing it opens nothing (the first reader does). The connection's lifecycle belongs to the `DatabaseLifecycle` provider (`nest/database/database-lifecycle.service.ts`): `buildApp()` opens it through `open()` (which binds the ORM to later swaps and runs the schema bootstrap below), the shutdown closes it through `close()`, and a restore or the demo reset swaps the file only through the database backup port, `DATABASE_BACKUP` (`nest/database/database-backup.interface.ts`; the SQLite implementation is `nest/backup/sqlite-database-backup.ts`: `VACUUM INTO` snapshot, close, atomic file swap, `reopen()`). The port works on `DatabaseLifecycle.file`, the one resolved path (`TREK_DB_FILE` or `data/travel.db`), and a snapshot that fails fails the backup rather than archiving the live file. `MaintenanceRepository` is provided only by `MaintenanceModule`'s factory and injected everywhere else; no consumer constructs it. A provider that has to follow every reopen (the demo reset job saves the first demo baseline after a restore's re-bootstrap seeded the example trips) registers with `DatabaseLifecycle.onReopened()`, which runs after the reopen's schema bootstrap; a listener contains its own failures, since one that throws fails the reopen. MikroORM's migrations (`db/migrations/`) are the only schema source, **including for tests**: the hand-kept `schema.ts`/`migrations.ts`/`seeds.ts` builders and the parity test that guarded them are gone. Seeding is the MikroORM seeders in `db/seeders/`, applied by `db/orm.ts` from `buildApp()` before anything reads. An install the retired positional runner migrated (a `schema_version` row, no `mikro_orm_migrations` rows) is baselined by `db/legacy-baseline.ts`: the migrations whose `Legacy migration step N` docstring is ≤ its version are recorded as executed (never replayed) in the same transaction as the migrator run, while the baseline migration itself still runs first, as the legacy runner's `createTables()` did on every boot; anything it cannot map refuses the boot. Before a boot applies pending migrations to a file database that holds anything, `db/pre-migrate-snapshot.ts` writes a `VACUUM INTO` copy next to it (`pre-migrate-<schema>-<time>.db`, `<schema>` being `legacy-<schema_version>` or the last recorded migration's timestamp; the newest `TREK_DB_PRE_MIGRATE_SNAPSHOT_KEEP` stay) and the newer-database refusal names the matching copy; a copy that cannot be written refuses the boot unless `TREK_DB_PRE_MIGRATE_SNAPSHOT=false`. It is off under `NODE_ENV=test` unless a suite sets that variable to true, and a restore's re-bootstrap skips it (the archive is the copy). After the migrator, `db/email-case-index.ts` creates the case-insensitive unique index on `users.email` that its migration had to defer on an install holding two accounts whose emails differ only in case (flag `email_case_index_pending`). `db/orm-driver.ts` binds the ORM to that same connection instead of opening a second one — with `:memory:` under test, a second connection is a second, empty database. Kysely statements (`this.kysely<...>()`) type against `DB` from `db/kysely/db.ts`, narrowed with `Pick<DB, 'trips' | 'days'>`; those files are generated from the migrated schema by `scripts/generate-db-types.ts`, so a migration that adds or changes a column is followed by `npm run gen:db-types`, never by a hand-written table interface. Every read and write goes through a repository in `db/repositories/` (each extends the shared `TrekRepository` base in `db/repositories/_shared/`, which validates the request context before delegating to MikroORM) and, for multi-statement writes, `UnitOfWork.transactional(...)` (`nest/database/unit-of-work.ts`, provided by the global `OrmModule`) — there is no `DatabaseService`/`DatabaseModule` to inject any more. Entrypoints outside an HTTP request — an MCP tool call, a plugin RPC dispatch, a WebSocket message, a cron job, boot-time seeding, a backup restore — open one explicitly with `withRequestContext()` (`nest/database/request-context.ts`), since only the pathless `mikroOrmRequestContext` middleware `buildApp()` mounts (with `@mikro-orm/nestjs`'s own `registerRequestContext` turned off in `app.module.ts`, UPLOADS-P16) forks an `EntityManager` per HTTP request. `NODE_ENV=test` ⇒ isolated `:memory:` DB per vitest worker, opened from a snapshot `tests/global-setup.ts` migrates once per run; `TREK_DB_FILE` ⇒ explicit file DB (Playwright harness).
