refactor(workspace-status): typed constants + AST-based drift gate

Browse Source 
Eliminate raw 'awaiting_agent'/'hibernating'/'failed'/etc string literals
from production status writes. Adds models.WorkspaceStatus typed alias and
models.AllWorkspaceStatuses canonical slice; every UPDATE workspaces SET
status = ... now passes a parameterized $N typed value rather than a
hard-coded SQL literal.

Defense-in-depth follow-up to migration 046 (#2388): the Postgres enum
type was missing 'awaiting_agent' + 'hibernating' for ~5 days because
sqlmock regex matching cannot enforce live enum constraints. The drift
gate is now a proper Go AST + SQL parser (no regex), asserting the
codebase ⊆ migration enum and every const appears in the canonical
slice. With status as a parameterized typed value, future enum mismatches
fail at the SQL layer in tests, not silently in prod.

Test coverage: full suite passes with -race; drift gate green.

// Static drift gate: every workspaces.status literal written in the Go
// tree must exist in the workspace_status enum defined by the migrations.
// Static drift gate: every value declared in models.AllWorkspaceStatuses
// must exist in the workspace_status enum after every migration applies.
//
// Why this exists: the `workspace_status` enum (migrations 043 + 046)
// shipped without 'awaiting_agent' even though application code wrote
// that value, and every UPDATE silently failed in production for five
// days before the gap surfaced (see 046_workspace_status_awaiting_agent.up.sql).
// The unit tests passed because sqlmock matches SQL by regex, not against
// a live enum constraint.
// Why this exists: the workspace_status enum (migration 043) initially
// shipped without 'awaiting_agent' and 'hibernating' even though
// application code already wrote both. Every UPDATE silently failed in
// production for five days because:
//
// Approach: extract every Go string literal whose body matches
// (?i)workspaces[^a-z_].*status (so "UPDATE workspaces SET status",
// "FROM workspaces WHERE ... status", "INSERT INTO workspaces ... status",
// CTEs that reference workspaces, etc.). For each such SQL fragment,
// pull the single-quoted status values out of `status =`, `status IN`,
// `THEN`, and `ELSE`. Every value must be in the union of CREATE TYPE +
// ALTER TYPE ADD VALUE across all migrations.
// - Status values were ad-hoc string literals scattered across raw
// SQL strings in 8+ files, with no compile-time check.
// - sqlmock matched SQL by regex, not against the live enum.
// - Errors were dropped or log-and-continued at every call site.
//
// The fix is layered. This gate is the static layer:
//
// - models.AllWorkspaceStatuses is the source of truth for the
// codebase side. Every status write goes through one of those
// typed constants (the parameterized-write refactor enforces this).
// - The migrations are the source of truth for the DB side.
// - This test parses both and asserts the codebase set ⊆ migration set.
//
// If you add a new status:
//
// 1. Add a `Status…` constant in models/workspace_status.go AND
// append it to AllWorkspaceStatuses.
// 2. Open a migration `ALTER TYPE workspace_status ADD VALUE 'X'`.
// 3. This test confirms both happened in the same PR.
//
// If you intend to retire a status: keep it in the enum as long as any
// row could legitimately still hold it, then drop it from
// AllWorkspaceStatuses (the gate runs the inclusion in one direction
// only — extras in the enum are fine).

// Workspace status — typed constants that mirror the `workspace_status`
// Postgres enum (migrations 043 + 046). Every UPDATE/INSERT against
// `workspaces.status` MUST use one of these constants; raw string
// literals are forbidden (see internal/db/workspace_status_enum_drift_test.go,
// which fails the build if a literal sneaks in).
//
// Why typed: pre-2026-04-30 the enum migrated without `awaiting_agent`
// and `hibernating` even though application code wrote those values.
// Every UPDATE silently failed with `invalid input value for enum
// workspace_status: ...` for five days because:
//
// - Status values were ad-hoc string literals scattered across
// ~15 raw SQL strings in 8 files. Typos (e.g. 'hibernating' vs
// 'hibernated') and missing-from-enum cases were invisible to
// the compiler.
// - sqlmock (the unit-test layer) matched SQL by regex, not against
// the live enum constraint.
// - Errors were dropped or log-and-continued at every call site.
//
// Typed constants close the first leg by making the bug uncompilable:
// adding a new status forces both this file AND the migration to
// change in the same PR; typos at call sites become "undefined: ..."
// at build time, not silent runtime failures.
// WorkspaceStatus is the type-safe alias for values written into
// `workspaces.status`. Its underlying type is string so it flows
// through database/sql args and JSON marshalling unchanged.
