[extensions] CRM improvements: crm_ prefix, FTS search, meeting prep, stale detection

[pintomatic]

Summary

Implements improvements to the Professional CRM extension based on the original proposal in #93:

• crm_ prefix: Renames all 8 tools to use the crm_ prefix, as agreed by @matthallett1 in the issue thread. Cleaner namespace, consistent with how other extensions could prefix their tools
• Full-text search: Adds PostgreSQL FTS with GIN indexes on contacts and interactions. crm_search_contacts now returns ranked results via ts_rank. Graceful ILIKE fallback if the RPC function hasn't been deployed yet
• crm_prep_context (new tool): Meeting prep briefing — aggregates contact profile, recent interactions, open opportunities, pending follow-ups, and relationship health into one call. The "power tool" from the original proposal
• crm_stale_contacts (new tool): Finds relationships going cold — contacts with no interaction in N days, ordered by staleness. Proactive network maintenance
• Version bump: 1.0.0 → 1.1.0
• Contributor credit: Added to metadata.json

These additions come from running a similar system in production (Kernal) with ~400 contacts — the meeting prep and stale detection patterns are the most-used features.

Changes

File	What changed
index.ts	8 tools renamed to crm_*, 2 new tools added, FTS search with fallback
schema.sql	Generated fts tsvector columns, GIN indexes, crm_search_contacts_fts RPC function
metadata.json	Version bump, contributor field, updated date
README.md	Updated tool list with new names and descriptions

Test plan

• Deploy edge function and verify all 10 tools respond
• Test FTS: crm_search_contacts with multi-word queries returns ranked results
• Test FTS fallback: works even without the RPC function (ILIKE path)
• Test crm_prep_context: returns aggregated briefing for a contact with interactions + opportunities
• Test crm_stale_contacts: returns contacts ordered by days since last contact
• Verify existing tools (crm_add_contact, crm_log_interaction, etc.) work identically to before

Thanks for the contribution, and welcome. This is a solid set of improvements to the professional-crm extension — full-text search, meeting prep, and stale-contact detection are genuinely useful additions.

Checked schema.sql: the changes are additive and idempotent — generated fts tsvector columns via ADD COLUMN IF NOT EXISTS, GIN indexes via CREATE INDEX IF NOT EXISTS, and a CREATE OR REPLACE search function. No destructive migration, and the core thoughts table is untouched. The crm_ prefix is applied to the tool names for namespacing — that changes the tool names an existing install exposes, which MCP clients re-discover, so it is a soft break with no data migration.

This is a meaningful rework of a curated extension, so it is the maintainer's call. Recommend maintainer review.
