feat: add human-like behavior, Spotify tools, task scheduler; remove crypto/TON tools

[TenSapphire]

Summary

• Adds human-like behavior to the Telegram agent: variable typing delays, context-aware reply probability, time-of-day-aware pacing, and natural writing-style imperfections (typos, filler phrases, edit-after-send).
• Adds a bounded conversational relationship/rapport tracker (never grants permissions) and a lightweight emotional-state tracker that inform the system prompt.
• Adds Spotify integration tools (track lookup, audio preview analysis) and a telegram_analyze_music tool.
• Adds a general-purpose TaskScheduler (repeating scheduled tasks) alongside the existing one-shot scheduled task handler, plus telegram_list_scheduled_tasks / telegram_cancel_scheduled_task tools.
• Adds telegram_update_profile_photo and DM-burst batching (MessageHandler.handleBatch) so rapid follow-up DMs merge into one turn instead of firing off separate replies.
• Removes the DEX (Ston.fi/DeDust), TON DNS, and TON wallet tool namespaces to shrink the default tool surface and dependency footprint; sdk.ton is now only constructed when ton_features.enabled is set, so these can come back as an opt-in plugin later.

Notes for reviewers

• This branch predates a large, unrelated upstream refactor of src/agent/runtime.ts and src/index.ts (splitting them into turn-preparation.ts / loop/executor.ts / response-finalizer.ts and app/agent-lifecycle-controller.ts / app/message-pipeline.ts, respectively). The merge/rebase against main re-homed this branch's feature code (emotional/relationship context, media+reaction message framing, DM debounce, reaction-event wiring, task-scheduler lifecycle) into the new module locations rather than reintroducing the old monolithic structure.
• src/memory/schema.ts: bumped CURRENT_SCHEMA_VERSION to 1.26.0 and added a migration for the new relationship_profiles / relationship_proposals / relationship_overrides tables and the tasks.repeat_every_ms column (both were previously ad-hoc CREATE TABLE IF NOT EXISTS calls inside RelationshipStore's constructor, which broke under lightweight test DB mocks — moved to the central schema like every other feed table).
• docs-sdk/pages/tools-telegram.html updated with the four new Telegram tools so the product-surfaces doc-coverage test stays accurate.
• Typecheck, lint, and the full test suite pass. Ten pre-existing test failures remain on this Windows dev box only (file-permission 0o600 checks, symlinkSync EPERM without elevated privileges, and one locale-dependent number-formatting assertion) — none touched by this branch's diff; they're expected to pass in CI on Linux.

Test plan

• npm run typecheck
• npm run lint
• npm test (2020/2030 passing; the 10 failures are pre-existing Windows-only environment issues, see notes above)
