feat(language-server): complete attribute names and required arguments - #30249

…#30261)

## Linked issue

n/a — no Linear ticket. Follow-up to prisma#30229 (roadmap removal) and prisma#30248
(Prisma 8 rename).

## At a glance

Docs-only PRs could not enter the merge queue: `Size Limit` is a
required check, and the bundle-size workflow skipped the whole job on an
inert diff, so the check never reported. prisma#30229 needed an admin merge
for exactly this reason. The job now always runs and only its steps
skip.

## Summary

Three leftovers from the roadmap removal in one commit, plus a second
commit that fixes the test-database idle timeout behind today's
`Connection terminated unexpectedly` failures.

### The idle-timeout mismatch

`createDevDatabase` in `@repo/test-utils` started the dev Postgres with
a one-second idle timeout, while the Postgres driver's pool keeps an
idle client for thirty seconds. Any test that pauses more than a second
between queries then gets a dead client back from the pool: `Client has
encountered a connection error and is not queryable`, wrapped as
`SqlConnectionError: Connection terminated unexpectedly`. Coverage
instrumentation makes such pauses routine, which is why the
adapter-postgres native-enum lifecycle suite failed the Coverage job on
five branches today (prisma#30249's queue run, prisma#30241, `prepare-orm`,
`prisma-8-skill-rc9-refresh`, prisma#30262 four times in a row) while passing
every plain shard.

Three suites had already worked around it with a per-call thirty- or
sixty-second override and a comment explaining exactly this. The default
now matches the pool (thirty seconds), the three redundant overrides are
gone, the telemetry harness keeps its sixty, and the returned handle
exposes the setting so the test can assert it.

### The roadmap leftovers

1. **`ROADMAP.html` is deleted.** It was the rendered twin of the
`ROADMAP.md` that prisma#30229 removed and still described the rc.1 plan.
2. **`scripts/lint-legacy-name.mjs` no longer cites the deleted
roadmap.** Two of its temporary allowances pointed at "ROADMAP.md § 3"
as the task that retires them; they now name the pending identifier
rename directly. The file-specific allowance for the roadmap itself is
gone with the files, and so is its test.
3. **The `Size Limit` job always reports.** The inert-diff condition
moves from the job to each step, following the pattern the CI workflow
already uses for its required `Test` summary job.

## Behavior changes & evidence

- **CI:** a docs-only PR now gets a green `Size Limit` check instead of
a skipped one, so auto-merge can enqueue it. Evidence: this PR touches
`.github/` and `scripts/`, so it is non-inert and exercises the real
path; the inert path is exercised by the next docs-only PR.
- **Lint:** `pnpm lint:legacy-name` still passes on main; `node --test
scripts/lint-legacy-name.test.mjs
scripts/lint-workflow-triggers.test.mjs` passes (29 tests).

prisma#30249)

Add registry-driven PSL attribute discovery: attribute names, top-level
named argument keys, and required-argument insertion for snippet-capable
editors.

## Changes

- **Configured attributes:** resolve field/model attributes from
authoring contributions and block attributes from their declaring
descriptors, using current document symbols and factory context.
- **Concrete completion contexts:** use distinct field/model/block
attribute-name and named-key kinds, with direct classifier paths instead
of a shared level/owner classifier shape.
- **Cursor and edits:** handle incomplete attribute names/keys through
PSL AST spans, argument lists, names and token streams; no
completion-time source reparse or source-text delimiter balancing.
- **Snippets:** insert required positional and named arguments with
empty editable slots; leave optional parameters for named-key discovery.
Clients without snippet support receive plain-text names.
- **Dependency ownership:** postgres public shell packages mirror direct
catalog dependencies declared by their bundled internal packages; no
helper override or trust-policy change is used.
- **Upgrade record:** declares the extension-manifest dependency fix as
no extension-author action in
`skills/prisma-8/upgrading/extension/upgrades/8.0.0-rc.9-to-8.0.0-rc.10/instructions.md`.

## Why

Attribute interpretation already defines the grammar. Completion
consumes those same definitions rather than maintaining a hardcoded
language-server attribute table, and remains available from the resolved
control stack even when interpretation reports diagnostics.

**Scope:** slice 2 of attribute autocomplete plus the postgres
dependency-ownership fix needed by publication checks. No recursive
value or nested function-argument suggestions, parser/type-kit redesign,
ADR changes, pnpm trust-policy changes, or dependency overrides.

## Verification

- Independent exact-completion review passed for commit
`7f25d1abea11c614489121aa10b6227e57d772a2`: concrete kinds, direct
classifiers, `Function` attribute completion items, control-stack-driven
availability, and AST/token-based edit ranges.
- Dependency ownership review passed for `66a2a71631`: direct package
dependencies are the source of truth, helper override removed, no
trust-policy or unrelated dependency-resolution changes.
- `pnpm --filter @internal/language-server lint` exited 0; Biome
reported 10 infos only.
- `pnpm check:upgrade-coverage --mode pr --prev origin/main` exited 0.
- `pnpm check:upgrade-coverage --prev origin/main` exited 0.
- `pnpm lint:skills` exited 0.
- `git diff --check origin/main...HEAD` exited 0.
- Previously reported gates: LS tests/typecheck, root typecheck/deps,
and full build passed. The full suite is not claimed green here.
