Add local environment lifecycle (#4297)

## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies.
> - Every heartbeat run needs a concrete place where the agent's adapter
process executes.
> - Today that execution location is implicitly the local machine, which
makes it hard to track, audit, and manage as a first-class runtime
concern.
> - The first step is to represent the current local execution path
explicitly without changing how users experience agent runs.
> - This pull request adds core Environment and Environment Lease
records, then routes existing local heartbeat execution through a
default `Local` environment.
> - The benefit is that local runs remain behavior-preserving while the
system now has durable environment identity, lease lifecycle tracking,
and activity records for execution placement.

## What Changed

- Added `environments` and `environment_leases` database tables, schema
exports, and migration `0065_environments.sql`.
- Added shared environment constants, TypeScript types, and validators
for environment drivers, statuses, lease policies, lease statuses, and
cleanup states.
- Added `environmentService` for listing, reading, creating, updating,
and ensuring company-scoped environments.
- Added environment lease lifecycle operations for acquire, metadata
update, single-lease release, and run-wide release.
- Updated heartbeat execution to lazily ensure a company-scoped default
`Local` environment before adapter execution.
- Updated heartbeat execution to acquire an ephemeral local environment
lease, write `paperclipEnvironment` into the run context snapshot, and
release active leases during run finalization.
- Added activity log events for environment lease acquisition and
release.
- Added tests for environment service behavior and the local heartbeat
environment lifecycle.
- Added a CI-follow-up heartbeat guard so deferred issue comment wakes
are promoted before automatic missing-comment retries, with focused
batching test coverage.

## Verification

Local verification run for this branch:

- `pnpm -r typecheck`
- `pnpm build`
- `pnpm exec vitest run server/src/__tests__/environment-service.test.ts
server/src/__tests__/heartbeat-local-environment.test.ts --pool=forks`

Additional reviewer/CI verification:

- Confirm `pnpm-lock.yaml` is not modified.
- Confirm `pnpm test:run` passes in CI.
- Confirm `PAPERCLIP_E2E_SKIP_LLM=true pnpm run test:e2e` passes in CI.
- Confirm a local heartbeat run creates one active `Local` environment
when needed, records one lease for the run, releases the lease when the
run finishes, and includes `paperclipEnvironment` in the run context
snapshot.

Screenshots: not applicable; this PR has no UI changes.

## Risks

- Migration risk: introduces two new tables and a new migration journal
entry. Review should verify company scoping, indexes, foreign keys, and
enum defaults are correct.
- Lifecycle risk: heartbeat finalization now releases environment leases
in addition to existing runtime cleanup. A finalization bug could leave
stale active leases or mark a failed run's lease incorrectly.
- Behavior-preservation risk: local adapter execution should remain
unchanged apart from environment bookkeeping. Review should pay
attention to the heartbeat path around context snapshot updates and
final cleanup ordering.
- Activity volume risk: each heartbeat run now logs lease acquisition
and release events, increasing activity log volume by two records per
run.

## Model Used

OpenAI GPT-5.4 via Codex CLI. Capabilities used: repository inspection,
TypeScript implementation review, local test/build execution, and
PR-description drafting.
