[Bug]: help() still returns "Unknown helper" for every helper on ego lite 0.4.6.14

Affected component

ego-browser runtime or CLI

What happened?

On the current official ego lite 0.4.6.14 app, help() is still non-functional even though #84 was closed as fixed.

Every helper name returns Unknown helper: <name>, and help() with no arguments returns an empty string. The helpers themselves work. Only the self-discovery catalog is empty.

This matches the original #84 failure mode: the shipped browser loads the SDK from a compiled / eval resource, so a docs map that is not actually present at runtime stays empty. #85 embedded docs at build time on dev, but that catalog is not present in the 0.4.6.14 app runtime. typeof click === "function" while help("click") still says unknown.

Related: the app-bundled skill is still 1.2.3 (2026-06-25), which is the same lag described in #273.

Steps to reproduce

ego-browser --version
# ego-browser 0.4.6.14
#   chromium 150.0.7871.101
#   node v24.18.0

ego-browser nodejs <<'EOF'
cliLog(help())
cliLog(help('click'))
cliLog(help('snapshotText'))
cliLog(typeof click)
EOF

Expected behavior

help() lists available helpers. help('click') prints the click signature and usage, as documented in SKILL.md.

Actual behavior

Unknown helper: click
Unknown helper: snapshotText
function

help() with no arguments prints an empty string.

Version

ego lite 0.4.6.14; bundled ego-browser skill 1.2.3 (2026-06-25); Chromium 150.0.7871.101; Node v24.18.0

Environment

macOS 26.5.0, Apple Silicon (arm64), Claude Code

Additional context

• Official channels all report 0.4.6.14 as latest: ego-browser upgrade → "already up to date"; About page after recheck → "ego 已是最新版本 / 版本 0.4.6.14"; Omaha updatecheck.status=noupdate; changelog latest heading is 0.4.6.14; official DMG x-amz-meta-omaha-version: 0.4.6.14.
• A PR will add a runtime fallback so help() can recover signatures from live functions when the embedded catalog is empty or missing a helper. That is a defense in depth for the next app ship; the app still needs to ship the built catalog from dev.

Before submitting

• I searched the existing issues and did not find a duplicate of this 0.4.6.14 regression (original help() returns "Unknown helper" for all helpers #84 is closed).
• I removed secrets and sensitive browsing data from this report.

Fix PR: #289

It recovers help() signatures from live helpers when the embedded catalog is empty. Verified locally with npm test (314 pass). This does not patch the closed-source 0.4.6.14 app binary; it is a runtime fallback for the next ship.
