Pulse Telos dashboard: handleTelosOverview uses wrong parser — missions, problems, challenges, strategies always return empty

[packetsherpa]

Bug

After running /interview, the Telos dashboard shows empty sections for missions, problems, challenges, and strategies.

Root cause

observability.ts's handleTelosOverview passes those four sections through parseSections(), which splits content on ## markdown headings. But the corresponding TELOS files (MISSION.md, PROBLEMS.md, CHALLENGES.md, STRATEGIES.md) all use a - **M0:** text bold-bullet format — not headings.

// This only finds ## headings — finds nothing in these files
const missions = parseSourceHeadings(asLifeSections(life.mission), "M")

The sections contain only a ## Notes heading, so parseSections() returns just that block and parseSourceHeadings() finds no M-prefixed entries in it. Only goals worked because parseGoals() already handled the bullet format correctly.

Impact

Missions, problems, challenges, and strategies all silently return [] from the API, so the dashboard falls back to sample fixture content for those sections.

Fix

Add a parseBoldBulletItems(content, prefix) helper (mirroring the existing parseGoals pattern) and use it in handleTelosOverview in place of parseSourceHeadings for these four sections.
