fix(resume+ats): preserve full resume content; honest ATS scoring

LLM-tailored resume was producing a 1-page truncated mess with "Internal
Product" as the name, missing BYJU's/ML Edutech roles, missing Education,
empty Core Competencies, and a spam keyword footer (adani/yakult/godrej).
Reported ATS 49% → 93% was bogus — actual was 64% → 29%.

Resume generator:
- New _extract_candidate_name() handles ALL CAPS names + PDF spacing
- Rewrote experience parser to find all date ranges (incl. line wraps),
preserve all roles, sub-sections, and bullets (no 5-bullet cap)
- Section detection requires ALL CAPS to avoid "certifications;" mid-prose
cutting off experience early
- _inject_missing_keywords now uses a skill-pattern allowlist + company-
name blocklist; max 8 real skills, no raw keyword dump
- Core Competencies falls back to original resume's skills if LLM empty
- Template path reads full resume (was truncating to 120 lines)
- New _read_docx_text() walks body XML in order so tables appear under
their headers (was breaking section detection)

ATS scorer:
- _strip_keyword_spam() removes "ADDITIONAL SKILLS & KEYWORDS" sections
and bullet-dump lines before scoring
- Structural penalties: short resumes capped, missing Education/Skills
sections deduct points, single-role resumes lose 10pp
- Date-range regex matches both "Jan 2023 – Present" and "Oct 2021 – Dec 2022"

Verified: Original 64/100, Fixed tailored 79/100 (+15pp honest gain).

+## 2026-06-15 — Resume Generator + ATS Scoring: Critical Bug Fixes
+
+User reported the LLM-tailored resume came out as a 1-page truncated mess with
+header "Internal Product" (instead of the candidate's name), missing the BYJU's
+roles, ML Edutech role, Education, and Core Competencies sections, plus a spam
+"ADDITIONAL SKILLS & KEYWORDS" footer containing irrelevant words ("adani",
+"godrej", "yakult"). Reported ATS Before 49% → After 93%, but actual quality
+was the inverse.
+
+### Resume generator fixes ([src/resume_customizer.py](src/resume_customizer.py))
+- **Name extraction**: New `_extract_candidate_name()` handles ALL CAPS names
+  (e.g. "SAITEJA TIRUNAGARI") and PDF letter-spacing artifacts. The old
+  `[A-Z][a-z]+ [A-Z][a-z]+` regex matched mid-resume "Internal Product".
+- **Experience parser**: Rewrote to walk the experience blob, find all date
+  ranges (handles "Oct 2021 – Dec\n2022" line-wraps), and split at each role
+  boundary. Preserves all 4 roles (NxtWave + 2 BYJU's + ML Edutech) where
+  the old parser collapsed them into one.
+- **Sub-sections preserved**: Sub-headings (e.g. "AI Chatbot – Conversational
+  Conversion Funnel") rendered as bold inline so the original document
+  structure is retained, not flattened.
+- **Bullet cap removed**: Was truncating to 5 bullets/role; now renders all
+  bullets (~33 for the NxtWave role in the sample resume).
+- **Section header detection requires ALL CAPS**: Prevents mid-prose words like
+  "certifications;" or "projects," from prematurely terminating the
+  experience section.
+- **Education extraction**: Normalizes PDF letter-spacing
+  ("E D U C A T I O N" → "EDUCATION") and accepts "EDUCATION & CERTIFICATIONS".
+- **Core Competencies fallback**: When the LLM returns an empty competencies
+  list, falls back to extracting the original resume's skills section so the
+  section is never empty.
+- **Keyword spam removed**: `_inject_missing_keywords` no longer dumps every
+  missing JD keyword as a footer. New skill-pattern allowlist + company-name
+  blocklist drops "adani"/"yakult"/"godrej"-style noise and only inserts up
+  to 8 actual skills (Jira, Figma, Mixpanel, APIs, etc.) as a small italic
+  line under Core Competencies.
+- **Template path**: Reads the full original resume (was truncating to 120
+  lines).
+
+### ATS scoring fixes ([src/ats_scorer.py](src/ats_scorer.py))
+- **`_strip_keyword_spam()`**: Strips "ADDITIONAL SKILLS & KEYWORDS" sections
+  and bullet-dump lines (15+ separators in one line) before scoring, so raw
+  keyword stuffing can't inflate the score.
+- **Structural penalties**:
+  - Resume <400 words → capped at 55/100
+  - Resume <600 words → capped at 75/100
+  - Missing Education section → −12 pp
+  - Missing Skills/Competencies section → −8 pp
+  - Single-role experience (when word count <800) → −10 pp
+- **Date-range regex**: Now matches both `Jan 2023 – Present` and
+  `Oct 2021 – Dec 2022` formats for role counting.
+
+### DOCX reader fix ([src/resume_customizer.py](src/resume_customizer.py))
+- New `_read_docx_text()` walks the document body in XML order (paragraphs +
+  tables interleaved), so the Core Competencies table appears immediately
+  under its header. The old approach (paragraphs first, then tables) broke
+  section detection — CORE COMPETENCIES looked empty because the next line
+  was PROFESSIONAL EXPERIENCE.
+
+### Verified results
+Tested against the real resume PDFs and AiSensy Product Manager JD:
+- Original 3-page resume: 64/100 (Good) — no penalties
+- Old buggy LLM-tailored: 29/100 (Poor) — multiple penalties (short, missing
+  Education, missing Skills)
+- New fixed LLM-tailored: 79/100 (Good) — clean structure, all sections
+  present, +15pp honest improvement over original
+
+The previously reported "+44pp ATS improvement" was bogus (keyword stuffing
+inflated the after-score). Real improvement is now ~+15pp.
