Clean daemon script and config source comments

Parent epic: #11912

Context

#11912 is being reshaped into an epic with grouped cleanup subissues. This subissue owns daemon, lifecycle-script, maintenance-script, config-template, and residual ai/ source-comment surfaces not covered by the service-group subissues.

Current grouped baseline on origin/dev:

• ai/scripts/**/*.mjs: 96 diagnostic matches.
• ai/daemons/**/*.mjs: 50 diagnostic matches.
• ai/config*.mjs, MCP config templates outside the service-owned groups, and residual ai/**/*.mjs surfaces: remaining high-noise matches after the Memory Core, KB/Graph, and GitHub/shared groups are accounted for.

The Problem

Daemon and script comments often preserve incident history, PR lanes, or AC references directly in executable source. Config templates also accumulate release-era rationale that should be expressed as stable operator-facing contracts.

The Architectural Reality

This group covers long-running process entry points, bridge/wake/KB daemons, migration and maintenance scripts, lint/diagnostic utilities, and residual config templates. These surfaces are operationally sensitive: comments should tell agents and operators what the script/daemon/config owns now, not which historical lane produced it.

The Fix

Clean daemon, script, config-template, and residual ai/ source comments in grouped batches:

1. Rewrite incident/PR/AC/lane references into stable operational contracts.
2. Keep exact command names, env vars, config keys, log-message payloads, and public paths when those are current API.
3. Document false positives and residual runtime strings.
4. If a residual file belongs more naturally to another subissue during cleanup, move it by comment on #11912 rather than creating a per-file ticket.

Contract Ledger Matrix

Decision Record Impact

Aligned with ADR 0005 and ADR 0008. No ADR amendment expected.

Acceptance Criteria

• Clean daemon .mjs comments/JSDoc to durable operational intent.
• Clean script .mjs comments/JSDoc to durable operational intent.
• Clean config-template and residual .mjs comments/JSDoc not covered by other subissues.
• Preserve runtime behavior, command names, env vars, config keys, and public paths.
• PR evidence includes before/after focused counts and git diff --check.
• Parent #11912 remains open until all grouped subissues are complete.

Out of Scope

• Service groups covered by the Memory Core, KB/Graph, and GitHub/shared subissues.
• Runtime behavior changes.
• Generated mirrors and historical docs outside source .mjs comments.
