agent-driver speaks for itself, not for the product

[suleimansh]

I read packages/agent-driver as a stranger, the way I did with the skill. The code is fine; the package still talked as if it were a folder of The Framework. This PR makes it speak for itself. Two names change on the way: the actions run branch is claude/<session id> (no framework- infix), and the product now passes its workflow name instead of the package assuming it.

Text a package user reads

• SPEC.md + every module and test SPEC: "The Framework", "the dashboard", "the daemon" are gone. The product embedding the package is the caller (one word, in the glossary); its UI is the caller's UI. The stories are otherwise unchanged.
• codex.SPEC.md / codex.ts claimed the product announces at startup that the spending cap cannot apply to Codex. The product does no such thing today; the sentence is gone from the package, and the SPEC now says what the package can promise: a caller must not pretend the cap applies.
• Doc comments that ship in the .d.ts: the types.ts header no longer narrates decisions (@gemstack/framework CLI: wrap Claude Code (first driver) + localhost dashboard #166 "option A", "the runner seam", "three methods" for four), fake.ts no longer cites FRAMEWORK_FAKE or AiFake/FakeRunner, child-registry.ts/claude-code.ts/actions.ts no longer say "the framework", "the daemon", --browser.

Strings a package user sees at runtime

• [framework] claude-code prompt aborted, [framework] codex exited (1): …, [framework] fake …, the onEvent threw console line: the prefix is gone; the message already names the driver. The MCP temp dir is agent-driver-mcp-.

Product defaults baked in

• ActionsDriverOptions.workflow no longer defaults to framework-agent.yml; it is required, and cli.ts passes it.
• The branch each actions run pushes to is claude/<session id> (claude/actions-1-ab12cd34), was claude/framework-<session id>. branchPrefix still overrides the claude/ part.

Two code things

• runCliSession no longer defaults the driver name to claude-code; driver is required and the Claude driver passes it.
• runClaude (a 3-line wrapper, public, used only by its own tests) is gone; the tests call runCliSession with StreamJsonParser.

Left alone on purpose — design, not slop

• DriverImplId fixes claude-web, an implementation that lives outside the package.
• The package name agent-driver (unscoped) next to @gemstack/skill-branches.
• No README (files ships dist only; the SPEC is the read on GitHub).
• The public surface beyond runClaude: the session classes, both parsers, replayTranscript, readClaudeQuota, the engine and its types are the extension points index.SPEC.md describes.

No behaviour change except the two names above. Proof: root typecheck, 79 agent-driver tests, 1471 framework node tests + 864 dashboard tests green. FEATURES-SPEC.md untouched: no feature added or removed.
