* Initial work on postgres state store
* Run fix
* Replace pre-written CHANGELOG with proper changeset
The CHANGELOG was manually written with a version entry. This repo uses
Changesets to manage versioning, so add a proper changeset file instead.

* Add missing @vitest/coverage-v8 dev dependency
The vitest config specifies coverage provider "v8" but the package
was missing from devDependencies.

* Drop drizzle-orm, use raw postgres queries
The adapter only needs 3 simple tables with basic CRUD. drizzle-orm is
a full ORM that adds significant dependency weight for no real benefit
here. The ensureSchema() method was already using raw queries. This
halves the dependency surface to just the postgres driver.

* Add comprehensive unit tests for postgres state adapter
Test factory function edge cases (missing URL, env var fallbacks,
custom keyPrefix) and ensureConnected guard for all state operations.

* Document expired row cleanup limitation for postgres adapter
Unlike Redis, Postgres doesn't auto-delete expired rows. Document the
opportunistic cleanup behavior and provide SQL for periodic cleanup.

* Remove stale drizzle keyword from package.json
drizzle-orm was removed in a prior commit but the keyword remained.

* Fix expiresAt parsing in acquireLock
The postgres library returns timestamptz columns as JavaScript Date
objects, not strings. Wrapping in new Date() was unnecessary overhead.

* Document lock atomicity difference vs Redis adapters
The Postgres ON CONFLICT approach relies on row-level locking rather
than a single atomic SET NX PX like Redis. Note this for users who
need high-contention distributed locking.

* Use crypto.randomUUID() for lock token generation
Math.random() is not cryptographically secure and has a higher
collision risk in distributed environments. crypto.randomUUID() is
available in Node 16+ and provides better uniqueness guarantees.

* Delete CHANGELOG.md
* Add comprehensive unit tests for postgres state adapter
Mock the postgres module and SQL client to achieve 100% coverage
across statements, branches, functions, and lines. Tests cover
factory function, connection lifecycle, subscriptions, locking,
cache operations, and the owned-client disconnect path.

* Add setIfNotExists method and merge with main
Implement the setIfNotExists method added to the StateAdapter
interface since this branch diverged. Uses INSERT ... ON CONFLICT
DO NOTHING with RETURNING to atomically check-and-set.

* Add Telegram auto mode polling and init username fallback
* Expose Telegram resetWebhook API
* Refine Telegram API to longPolling and safer auto mode
* Fix: Environment variable cleanup sets `process.env.VERCEL` to the string `"undefined"` (truthy) instead of removing it, leaking a truthy VERCEL env var into subsequent tests.
This commit fixes the issue reported at packages/adapter-telegram/src/index.test.ts:661
**Bug explanation:**
In the test "auto mode stays in webhook mode on serverless runtime" (line 622), the cleanup code in the `finally` block at line 662 uses `process.env.VERCEL = undefined` when the env var wasn't previously set. In Node.js, `process.env` coerces all values to strings, so `process.env.VERCEL = undefined` actually sets `process.env.VERCEL` to the string `"undefined"`. This is truthy (`Boolean("undefined")` === `true`).
This was verified empirically:
```
process.env.TEST_VAR = undefined;
typeof process.env.TEST_VAR // "string"
process.env.TEST_VAR // "undefined"
Boolean(process.env.TEST_VAR) // true
```
The consequence is that after this test runs, `process.env.VERCEL` remains set to the truthy string `"undefined"`, causing `isLikelyServerlessRuntime()` to return `true` for all subsequent tests that run in the same process. This could cause any auto-mode tests that follow to incorrectly detect a serverless runtime and behave differently than expected.
**Fix explanation:**
Changed `process.env.VERCEL = undefined` to `delete process.env.VERCEL`, which properly removes the environment variable from `process.env`. After `delete`, `process.env.VERCEL` is `undefined` (the actual undefined value, not the string), and `Boolean(process.env.VERCEL)` correctly returns `false`. This matches the standard pattern for cleaning up environment variables in Node.js tests.
