feat: agentic loop for multi-step tasks + regression fixes (#148)

* fix: name extraction blocklist, memory preview escaping, and gitignore cleanup

- Add _NAME_BLOCKLIST to extract_user_name() to reject gerunds and UI-state
  words like "Sending" that were incorrectly captured as user names
- Collapse whitespace in get_memory_status() preview so newlines survive
  JSON serialization without showing raw \n escape sequences
- Broaden .gitignore from specific memory/self/user_profile.md to memory/self/
  and untrack memory/self/methodology.md (runtime-edited file)

* fix: catch Ollama connection errors in session.py + add 71 smoke tests

- Wrap agent.run() in session.py with try/except so Ollama connection
  failures return a graceful fallback message instead of dumping raw
  tracebacks to Docker logs
- Add tests/test_smoke.py with 71 tests covering every GET route:
  core pages, feature pages, JSON APIs, and a parametrized no-500 sweep
  — catches import errors, template failures, and schema mismatches
  that unit tests miss

* feat: agentic loop for multi-step tasks + Round 10 regression fixes

Agentic loop (Parts 1-4):
- Add multi-step chaining instructions to system prompt
- New agentic_loop.py with plan→execute→adapt→summarize flow
- Register plan_and_execute tool for background task execution
- Add max_agent_steps config setting (default: 10)
- Discord fix: 300s timeout, typing indicator, send error handling
- 16 new unit + e2e tests for agentic loop

Round 10 regressions (R1-R5, P1):
- R1: Fix literal \n escape sequences in tool responses
- R2: Chat timeout/error feedback in agent panel
- R3: /hands infinite spinner → static empty states
- R4: /self-coding infinite spinner → static stats + journal
- R5: /grok/status raw JSON → HTML dashboard template
- P1: VETO confirmation dialog on task cards

* fix: briefing route 500 in CI when agno is MagicMock stub

_call_agent() returned a MagicMock instead of a string when agno is
stubbed in tests, causing SQLite "Error binding parameter 4" on save.
Ensure the return value is always an actual string.

* fix: briefing route 500 in CI — graceful degradation at route level

When agno is stubbed with MagicMock in CI, agent.run() returns a
MagicMock instead of raising — so the exception handler never fires
and a MagicMock propagates as the summary to SQLite, which can't
bind it.

Fix: catch at the route level and return a fallback Briefing object.
This follows the project's graceful degradation pattern — the briefing
page always renders, even when the backend is completely unavailable.

-# Timmy Methodology
-
-## Tool Usage Philosophy
-
-### When NOT to Use Tools
-
-- Identity questions ("What is your name?")
-- General knowledge (history, science, concepts)
-- Simple math (2+2, basic calculations)
-- Greetings and social chat
-- Anything in training data
-
-### When TO Use Tools
-
-- Current events/news (after training cutoff)
-- Explicit file operations (user requests)
-- Complex calculations requiring precision
-- Real-time data (prices, weather)
-- System operations (explicit user request)
-
-### Decision Process
-
-1. Can I answer this from my training data? → Answer directly
-2. Does this require current/real-time info? → Consider web_search
-3. Did user explicitly request file/code/shell? → Use appropriate tool
-4. Is this a simple calculation? → Answer directly
-5. Unclear? → Answer directly (don't tool-spam)

-## Memory Management
-
-### Working Memory (Hot)
-- Last 20 messages
-- Immediate context
-- Topic tracking
-
-### Short-Term Memory (Agno SQLite)
-- Recent 100 conversations
-- Survives restarts
-- Automatic
-
-### Long-Term Memory (Vault)
-- User facts and preferences
-- Important learnings
-- AARs and retrospectives
-
-### Hot Memory (MEMORY.md)
-- Always loaded
-- Current status, rules, roster
-- User profile summary
-- Pruned monthly
-
-## Handoff Protocol
-
-At end of every session:
-
-1. Write `memory/notes/last-session-handoff.md`
-2. Update MEMORY.md with any key decisions
-3. Extract facts to `memory/self/user_profile.md`
-4. If task completed, write AAR to `memory/aar/`
-
-## Session Start Hook
-
-1. Read MEMORY.md into system context
-2. Read last-session-handoff.md if exists
-3. Inject user profile context
-4. Begin conversation
