#136 docs: add install --skill explainer section to user guide

[Anonymous]

Originally created by: kumaakh

Background

Suggested in PR [#133]. The user guide lists what install --skill writes but it's buried. Agents and new users hesitate to run installers they don't understand.

What to add

A short, visible section near the top of the install flow explaining:

• What files get written and where (~/.apra-fleet/bin/, ~/.claude/skills/pm/, hooks, statusline config)
• What it does NOT do (no system-level changes, no network calls, no background services)
• How to uninstall / what to delete if you want to remove it

Needs to be verified against actual installer behavior before writing — don't document from assumption.

Blocked on [#139] — once the --skill all/pm/fleet/none default change lands, the explainer section should document the new options rather than the old --skill flag. Pick this up as part of the [#139] docs update pass.

Fixed. README now has a dedicated --skill section (under the install accordion) listing all flag variants and what each installs. Verified present in main.
