fix(cli): add source discriminator to telemetry events

[miguel-heygen]

Summary

• Adds source: "cli" to all CLI telemetry events at the client level

Problem

PostHog dashboard shows ~10k renders but Temporal shows <400. The discrepancy exists because CLI local renders (hyperframes render) and web app renders share the same render_complete event name in PostHog with no way to filter them apart.

CLI events affected: cli_command, render_complete, render_error, init_template, browser_install — all now carry source: "cli".

Fix

Single-line change in packages/cli/src/telemetry/client.ts — the trackEvent wrapper already injects system metadata into all events, so adding source: "cli" there tags every CLI event automatically.

Companion PR on hyperframes-internal adds source: "web" to the web app's analytics wrapper. Together, dashboards can filter source = "web" to show only production renders.

Test plan

• Verified trackEvent call site — source is injected before user properties spread, so per-event props can't accidentally overwrite it
• No behavioral change to telemetry — only adds one new property to existing events

First review at 33f809f0. CI is red on three required checks — pulling those first.

CI status (Rule 5)

• File size check — failed at 25767325783
• Render on windows-latest — failed
• Tests on windows-latest — failed

The PR body doesn't address any of these. Per Rule 5, this can't APPROVE while a required check is red.

Audited

• packages/cli/src/telemetry/client.ts:75 (the one-line telemetry change)
• skills/hyperframes/SKILL.md (the 109/-4 skills diff — bundled with this PR)

Important — this PR bundles two unrelated changes that should ship as separate PRs

The PR body describes a single-purpose telemetry discriminator fix (one line, one file). The actual diff is:

packages/cli/src/telemetry/client.ts      +1 / 0     (telemetry — in PR body)
skills/hyperframes/SKILL.md              +109 / -4  (skills update — NOT in PR body)

The skills change is the same +109/-4 SKILL.md diff as #716 ("feat(skills): teach temporal thinking and visual variety") — same author, same commit shas 3073d0ab and e466b8d3. #762's history is [3073d0ab, e466b8d3, 33f809f0]; #716's is [3073d0ab, e466b8d3]. #762 is a strict superset of #716.

Pick one shape:

1. Drop the skills commits from this PR, leave just 33f809f0 (telemetry only) — single-purpose. #716 then lands the skills work.
2. Land this PR (skills + telemetry together), close #716 as merged-by-superset.

Either is fine, but the current state is two PRs with overlapping history — confusing for the merge queue and easy to double-merge.

Telemetry change — correctness review

packages/cli/src/telemetry/client.ts:75 injects source: "cli" into the properties spread inside trackEvent. Spread order is:

properties: {
  ...properties,        // caller's props
  source: "cli",        // <-- new
  cli_version: VERSION,
  os: process.platform,
  ...
}

source is BEFORE the system-metadata fields, so a caller passing { source: "user-override" } would have its value overwritten by the hardcoded "cli". PR body asserts this is intentional ("per-event props can't accidentally overwrite it"). That's the right shape — the discriminator should be authoritative.

Verified the dashboard impact: the companion hyperframes-internal PR mentioned in the body needs to land too, otherwise web-app renders still come through without source, defeating the filter. Worth flagging in the merge order.

Important — CI must be addressed before merge

The three failing checks need a look:

• File size check failing on a +1/-0 telemetry change is unusual; almost certainly the skills SKILL.md bumping past a size cap or the bundled .gitignore changes. If it's the skill, that's a structural decision (split the file vs. bump the cap).
• Windows render/test failures on this branch — pull the job logs; if these are flake, kick a re-run. If they're real, the skills bundle change may have broken windows-side path handling.

Verdict

Verdict: REQUEST CHANGES
Reasoning: Three required CI checks are red (File size check, Render on windows-latest, Tests on windows-latest); PR bundles a telemetry one-liner with the entire skills-temporal-thinking diff from #716, creating overlapping PR history. Either split this PR (telemetry only, drop the skills commits) or close #716 as superseded.
