Rename STACK_* env vars to HEXCLAVE_* in env templates, with legacy dual-read (#1588)
## Summary

Completes the env-var side of the Hexclave rebrand: every
`STACK_*`-prefixed variable (including `NEXT_PUBLIC_STACK_*` and
`VITE_STACK_*`) is renamed to `HEXCLAVE_*` across all checked-in `.env`,
`.env.development`, and `.env.example` files (30 files, ~135 keys).
Legacy `STACK_*` names keep working everywhere via dual-read, so
**existing deployments, `.env.local` files, and self-hosted setups need
no immediate migration**.

## How legacy names keep working

- **Server code** already resolves `HEXCLAVE_*` first with `STACK_*`
fallback via `getEnvVariable`. Direct `process.env.STACK_X` readers fed
by the renamed files (prisma seed, e2e tests/helpers, internal-tool
scripts, examples, `prisma.config.ts`) now read `HEXCLAVE_X || STACK_X`.
- **Client code** (Next.js build-time inlining) uses literal dual-read
expressions; the dashboard's `_inlineEnvVars` already had them.
- **Docker/self-hosting**: `docker/server/entrypoint.sh` (shared by the
server and local-emulator images) gets a generic two-way
`HEXCLAVE_`↔`STACK_` env mirror — runs at startup and again before
sentinel replacement — replacing the previous URL-trio-only mirror.
Operators can use either prefix.

## The empty-placeholder trap (`||` vs `??`)

The checked-in templates define empty placeholders (`HEXCLAVE_X=#
comment` parses to `""` via dotenv). With `?? `-based fallbacks, that
empty string would silently shadow a real value under the legacy name —
including legacy vars set in Vercel/CI env at build time, since the
tracked `.env` is present during builds. All fallback chains therefore
treat empty-as-unset (`||`):

- `getEnvVariable` and `getProcessEnv` in `packages/shared`
- the dashboard/docs/example literal dual-reads
- the generated SDK env getters (via
`packages/template/scripts/generate-env.ts`; the generated
`src/generated/env.ts` files are gitignored and regenerate at build)

## Other notable changes

- Tests that override env now set the canonical `HEXCLAVE_*` name (it
wins over `STACK_*`): e2e `cross-domain-auth`, backend
`internal-feedback-emails` in-source test.
- e2e `helpers.ts` port-prefix expansion loop also matches the
`HEXCLAVE_` prefixes.
- `docker/local-emulator/generate-env-development.mjs` reads source keys
canonically (legacy fallback) and emits canonical keys; regenerated
output matches.
- `rotate-secrets.sh` falls back to
`HEXCLAVE_DATABASE_CONNECTION_STRING`.
- Docs code snippets (`docs/code-examples`) renamed outright to
canonical names, consistent with #1571.
- OAuth callback `console.warn` in `packages/template/src/lib/auth.ts`
now says Hexclave.

## Migration note for the team

Local `.env.local` files with legacy `STACK_*` overrides keep working
**unless** the override targets a var that `.env.development` now sets
to a real (non-empty) `HEXCLAVE_*` value — the canonical name wins over
file precedence. Rename those keys in your `.env.local` once.

## Verification

- `typecheck` + `lint` pass on every touched package (shared, backend,
dashboard, e2e, internal-tool, cli, docs, template). Pre-existing
failures on dev (`admin-app-impl.ts` typecheck, dashboard metrics-page
errors) are unchanged (identical error counts with/without this change).
- `getEnvVariable`/`getProcessEnv` fallback semantics smoke-tested
directly (empty-HEXCLAVE → legacy fallback, HEXCLAVE wins when set,
defaults intact).
- `internal-feedback-emails` in-source vitest passes; emulator env
generator `--check` passes; `bash -n` on touched shell scripts.
- Two independent review agents audited the diff for correctness bugs
and coverage gaps; all confirmed findings are fixed in the third commit.

## Summary by cubic
Renamed all `STACK_*` env vars (including
`NEXT_PUBLIC_STACK_*`/`VITE_STACK_*`) to `HEXCLAVE_*` across env
templates and code, with dual‑read that treats empty as unset, detects
conflicts, ignores post‑build sentinels, and falls back to legacy names.
All GitHub Actions now use `HEXCLAVE_*`; local‑emulator e2e is fixed by
setting `NEXT_PUBLIC_HEXCLAVE_IS_LOCAL_EMULATOR` in CI.

- **Refactors**
- Added conflict‑aware dual‑read helpers (prefer `HEXCLAVE_*`,
empty‑as‑unset, ignore post‑build sentinels, preserve empty passthrough)
and used them across `packages/shared` (resolver + tests),
`apps/dashboard` inline/public envs (with tests), `apps/backend` Prisma
config/seed and vitest (accept both prefixes), `packages/cli`
(API/Dashboard URLs, project ID, `HEXCLAVE_EMULATOR_HOME`; tests),
Docker (`entrypoint.sh` mirroring + `rotate-secrets.sh` DB URL),
docs/components (`docs/src/lib/env.ts`), and examples; hosted/Vite apps
now error if both spellings differ.
- Port‑prefix expansion includes `HEXCLAVE_*`; backend tests use a new
helper to resolve DB connection strings; Prisma prefers
`HEXCLAVE_DATABASE_CONNECTION_STRING` with legacy fallback.
- Generated SDK env getters use plain `HEXCLAVE_*` || `STACK_*` (no
conflict throw); dashboard inline resolver preserves empty/sentinel
passthrough to avoid build failures; docs/examples include dual‑read
utilities.
- Tests now stub canonical `HEXCLAVE_*` flags (e.g., plan limits, bot
challenge, OAuth tokens, hosted handler) to avoid shadowing/conflict
with committed defaults.

- **Migration**
  - No immediate action; legacy `STACK_*` names still work.
- If both names are set with different values, builds/scripts error. Set
only `HEXCLAVE_*` or make both equal.
- SDK consumers won’t see conflict throws; update env names to
`HEXCLAVE_*` over time.

## Summary by CodeRabbit

* **Chores**
* Migrated environment variable names from the legacy `STACK_*` prefix
to the new `HEXCLAVE_*` prefix across backend, dashboard, tooling,
Docker, and examples.
* Updated environment/config resolution to prefer `HEXCLAVE_*`, treat
empty strings as unset, and detect conflicts when both `STACK_*` and
`HEXCLAVE_*` are set to different values.
* Updated local emulator, server startup, and env-generation workflows
to use the new names (with legacy fallback where applicable).
* **Documentation**
  * Updated docs and code examples to reference `HEXCLAVE_*` variables.
* **Tests**
* Refreshed unit and e2e coverage to validate dual-read behavior,
conflict detection, and empty-value handling.
