Alberto Schiabel 0abc629f5d refactor(cli): migrate to Effect 4 (4.0.0-rc.112) (#3901)
Rebuilds the Effect v4 port on top of `next` at `effect@4.0.0-rc.112`
(the newest release that clears the repository's 3-day
`minimumReleaseAge` gate). The three v3-compatible preparation PRs
(#4358, #4359, #4360) already landed on `next`, so this PR is now only
the cutover.

## What changes

- Pins `effect`, `@effect/platform-bun`, and `@effect/vitest` to exact
`4.0.0-rc.112`; drops `@effect/cli`, `@effect/platform`,
`@effect/platform-node`, and the `toml` override that existed only for
`@effect/cli`. The `ts/vendor/effect` source oracle moves to the
`effect@4.0.0-rc.112` release commit.
- Services become `Context.Service` classes with explicit `Default`
layers; `Either` becomes `Result`; `ParseResult` becomes
`Schema.SchemaError`; platform modules come from `effect/FileSystem`,
`effect/Path`, `effect/PlatformError`, `effect/unstable/process`, and
`effect/unstable/http`.
- The runner drives `Command.runWith` with v4's default help and error
rendering. `CliError.ShowHelp` carries its own exit code, help for
non-explicit invocations renders on stderr, and "Did you mean?"
suggestions render. `command-introspection.ts` is gone: v4 renders the
resolved command's help and the "missing value" tip itself.
- `composio --version`, `composio -v`, and `composio version` print the
same bare semver (`GlobalFlag.Version` is not enabled; the flag
spellings are rewritten to the `version` command before parsing).
- Root `--log-level` is a shared flag applied after the subcommand tree
is attached, so `composio --log-level Debug <subcommand>` both parses
and takes effect.
- Every `Flag.boolean` carries an explicit default, because rc.112 makes
boolean flags required when omitted.
- A `Result` is not an `Effect` at runtime in rc.112 even though the
type checker accepts `yield*` on it (the fiber dies with "Not a valid
effect"); every `Result` is lifted with `Effect.fromResult`, and the
skill/AGENTS guidance says so.
- Every `ChildProcess.make` site passes `extendEnv: true`, because
rc.112 no longer inherits the parent environment by default.
- `--log-level` and `COMPOSIO_LOG_LEVEL` are exact-match on the
`LogLevel` names (`All`, `Fatal`, `Error`, `Warn`, `Info`, `Debug`,
`Trace`, `None`) with no case folding, per the earlier review decision;
README updated.
- Spawned children pass `extendEnv: true`, because rc.112's
`ChildProcess` no longer inherits the parent environment by default.
- ISO timestamps decode through `Schema.DateTimeUtcFromString`;
`Schema.DateTimeUtc` is no longer a string codec in rc.112.
- `ConfigProvider.fromEnv()` snapshots the environment at construction
in v4, so providers that must observe later changes are built per read
(`plugin-hint.ts`, `install.cmd.ts`, `config.ts`) and tests use a
live-env provider helper.
- `cli-keyring` and `json-schema-to-effect-schema` are ported alongside
(the latter on `Schema.makeFilter`).
- The `effect-v4` skill, the `cli-command` and `typescript-testing`
references, `ts/packages/cli/AGENTS.md`, and the oxlint config are
updated to the rc.112 reality. The skill's example checker
(`.agents/skills/effect-v4/scripts/check-examples.mjs`, lifted from
#3851) compiles every TypeScript block in the skill against the pinned
packages.
- The `js-yaml` overrides move to the 4.3.2 / 3.15.2 lines that
GHSA-2883-xcg3-v3hh requires; `pnpm audit --prod` is clean apart from
the already-ignored `extract-zip` advisory.

## Behaviour notes

- `composio <unknown> --help` now prints the root help with exit 0 (v4's
global `--help` handling); `composio <unknown>` without `--help` still
fails with the unknown-subcommand error.

## Validation

- `pnpm --filter @composio/cli typecheck` (src + test): 0 errors
- `pnpm --filter @composio/cli test`: 127 files, 1325 tests pass, 1
skipped; `validate:boundaries` and `validate:skills` pass
- `@composio/cli-keyring` and `@composio/json-schema-to-effect-schema`
typecheck, test, and build pass
- `pnpm validate:agent-skills` and `pnpm validate:skill-routing` pass
(19 skills)
- oxlint clean on `ts/packages/cli`, `cli-keyring`,
`json-schema-to-effect-schema`
- CLI bundle and standalone binary build; smoke-checked `version`,
`--version`, `-v`, `--help`, unknown subcommand, unrecognized flag,
missing flag value
- Docker CLI e2e suites pass against an image built from this branch:
`version`, `toolkits-list`, `toolkits-info`, `toolkits-search`,
`setup-plugins`, `run`. `whoami` (needs an API key), `install` (needs a
release dir), and `upgrade` (needs network) were not run.

No changeset: `@composio/cli` is Changesets-ignored and the ported
sibling packages are private. Human-facing notes are in
`ts/packages/cli/CHANGELOG.md`.
