New module claude_session.py provides query() and query_json() that
run prompts via `claude -p` CLI — uses the claude.ai session, zero API cost.
Converted 6 services:
- claims_extractor.py: extract_claims_with_ai
- brainstorm.py: brainstorm_directions
- block_writer.py: write_block (was streaming+thinking, now simple)
- qa_validator.py: claims_coverage check
- style_analyzer.py: 3 API calls (single pass, multi pass, synthesis)
- learning_loop.py: extract_lessons
Only extractor.py still uses Anthropic API (for PDF OCR with Vision).

Two fixes for claims_coverage false negatives (55% → expected ~85%+):
1. Model upgrade: Haiku → Sonnet for semantic matching. Haiku missed
obvious matches (e.g., paragraph about "כריתת עצים" not matching
claim about tree cutting). Sonnet understands context better.
2. Filter: only check appellant/respondent claims, not committee or
permit_applicant claims. Committee claims are defensive positions
("the application complies with the plan") — they don't need to
be "addressed" in the discussion section.
3. Send full discussion text (was truncated to 12K chars).

block_writer: new renumber_all_blocks() function that renumbers all
paragraphs across all blocks sequentially (1, 2, 3...). Handles both
plain "N." and bold "**N.**" formats. Added missing 'import re'.
qa_validator: sequential_numbering check now matches bold-formatted
numbers (**N.**) in addition to plain (N.).
Tested on Hecht: renumbered 115 paragraphs across 7 blocks, QA 6/6.

claims_coverage now uses Claude Haiku to check if each claim is
semantically addressed in the discussion, not just keyword-matched.
- Sends all claims + discussion to Claude in one API call
- Returns addressed/partial/missing for each claim
- Handles markdown code block wrapping in response
- max_tokens 4096 (was 2048) for 48+ claims
Result on Hecht: 45/48 addressed (94%), 1 partial, 3 missing.
The 3 missing are genuinely unaddressed (personal/procedural claims).
Previously keyword check showed 47/48 but missed semantic gaps.

block_writer: _build_claims_context now filters out block-zayin claims
(from final decision) and uses only claims from original pleadings.
Reduces noise from 78 to 48 real claims for Hecht case.
qa_validator: claims_coverage check rewritten:
- Filter block-zayin claims (same reason)
- Keyword-based matching instead of 3-word phrase matching
- 25% keyword overlap threshold (was: any 3-word match)
- Allow up to 20% uncovered claims before failing
- Check both block-yod and block-zayin for coverage
Result: Hecht case QA goes from 4/6 to 6/6, 47/48 claims covered (98%).
