refactor(cli): cover db schema declarative sync with effect lint (CLI-2409)

[7ttp]

TL;DR

brings supabase db schema declarative sync under the effect lint, which completes the db family

whats introduced?

effect lint applied to db schema declarative sync:

• the per subcommand allow list entries collapse into one db/** entry
• typed errors are yielded directly
• sync timestamps come from DateTime with the same output
• tests use FileSystem and Path, set env through withEnvVar, and pin the transaction mode message
• the e2e test runs through the effect native harness with its project in acquireUseRelease

• closes: CLI-2409

🤖 AI Review

One minor test coverage gap is confirmed. The lint coverage finding is refuted: the new negated glob includes the db tree in Effect lint. No additional defect was verified. Tests were not run because dependencies are absent.

Findings

Severity	Location	Category	Sources	Claim
🟡 MINOR	apps/cli/src/commands/db/schema/declarative/sync/sync.integration.test.ts:1532	test-coverage	claude	The new invalid transaction mode test checks only the error message. It does not verify the outward error tag or that no migration file was written.

Refuted findings (kept for transparency, not posted as review comments)

• .oxlintrc.effect.json:15 (lint-coverage): The new glob excludes the entire db command tree from Effect lint, including the changed sync code.
  Refuted: The ! pattern reverses the initial ignore pattern and includes the db tree in lint coverage. The trusted baseline config uses the same negated pattern convention for other included command directories.

Effect-lint coverage for declarative sync looks mechanical.

Prompt and compatibility failures are the same tagged errors, now yielded directly. The oxlint include widens to commands/db/** now that the stack covers that tree. Tests are still there; the unknown pg-delta transaction mode case was added.
