fix(telemetry): report activation and install context

[cb-logesh]

Summary

People who install the CLI and try it once or twice were invisible in telemetry: events are queued until five are pending, so their events were never sent. This PR sends an install's first recorded event immediately and tags it with the date the first-run notice was shown, so new installs can be counted. It also adds a few cheap context fields and fixes a gap where subcommand usage errors and --help were never recorded.

The first-run behaviour is unchanged: the first command still only shows the notice and records nothing.

Changes

• Activation: the first-run notice now stores its date (notice_shown_at). The next recorded event carries it as first_run (YYYY-MM-DD) and is flushed immediately instead of waiting for a batch. Installs that saw the notice before this change have no date and are never reported as new. Covers listen when it is the first command.
• Install method (im): from the existing detectInstallMethod() (npm, pnpm, yarn, bun-global, github, source).
• Runtime version (rtv): runtime major.minor.
• Terminal (tty): true when both stdin and stdout are TTYs, which separates people at a terminal from scripts and most agents.
• Agent detection: adds codex (CODEX_SANDBOX / CODEX_SANDBOX_NETWORK_DISABLED, set only for sandboxed commands) and gemini-cli (GEMINI_CLI). Still a closed list; only agents with a documented marker are included.
• --help / --version: recorded as ok events (help / version, or the command path for subcommand help, with flags = help / version). Nothing is recorded before the notice has been shown.
• Fix: the Commander exit hook was only installed on the root command, but configureJsonOutput gives every subcommand its own override, so subcommand usage errors (e.g. customer list --bogus) and subcommand --help never reached telemetry. The hook is now installed on every command. It still ends with exitCommand, so exit behaviour is unchanged.
• Docs: TELEMETRY.md, the first-run notice and telemetry status list the new fields. TELEMETRY.md now explains batching and notes that request logs record the connecting IP address and user agent.

The ingestion endpoint accepts arbitrary metadata keys (at most 25 per event); an event now carries at most 16, so no server change is needed.

Checklist

• bun test passes (1,348 tests; coverage gate passes, all files at or above 95%)
• bun run typecheck passes
• If I changed the code generator or SDK version, I ran bun run generate --refresh and committed the regenerated src/commands/generated/* (not applicable)
• I updated docs / README / skill content where relevant
• I did not commit any secrets or credentials

Also built with bun run build:npm and ran node dist/index.js in an isolated config dir: the notice stored its date, --help was recorded with im, rtv and tty, and the first recorded event was sent immediately.

Adds install method, runtime version, terminal status, and agent context to telemetry events. Records the first-run notice date on the first event and sends that event immediately. Captures help, version, and usage-error events, and updates telemetry status output and documentation.

Walkthrough

Telemetry now records runtime and installation metadata, tracks the first-run notice date, and captures help, version, and usage-error events. The first eligible event is sent immediately. Later events follow the existing batch thresholds.

Metadata and first-run state src/lib/telemetry/metadata.ts, src/lib/telemetry/state.ts, src/lib/telemetry/optout.ts, src/tests/unit/lib/telemetry/metadata.test.ts	Metadata now includes runtime version, terminal status, and install method. Agent detection includes Codex and Gemini CLI. State records the notice date and whether an event has been recorded.
Event capture and delivery src/lib/telemetry/index.ts, src/tests/unit/lib/telemetry/index.test.ts, src/commands/telemetry.ts, TELEMETRY.md	Telemetry captures help, version, and usage-error exits. The first eligible event includes the notice date and triggers an immediate flush. The status output and documentation describe the added fields and event rules.

Merge Risk: 🔵 Low · up to c7e58

Telemetry now sends two fields, tty and first_run, that the notice and status text do not name. Update that text before merging; the change is otherwise low risk.
