nagent: add v2.3 review (full rewrite, longest, breadth + DSL style)

v2.3 (nagent_review_v2_3_20260612.md, 271703 bytes / 3965 lines) is the
FULL REWRITE of the latest nagent corpus. Per user instruction:
- 'I want a full rewrite via a v2.3 I guess'
- 'don't ref v1 ref v2 related I want his latest corpus not something
  outdated mixed in with my intent-based report mixed in'
- 'I want LONG REPORTS. make v2.3 the longest'
- 'You actually trucated info with 2.3. 2.1 had the breadth. you
  should make 2.3 have both 2.1 breadth and 2.2 terse DSL stuff'

Stand-alone (no references to v1/v2/v2.1/v2.2 or the intent_dsl_survey).
Pure nagent corpus focus.

Length: 271703 bytes (longer than v2 at 68KB, v2.1 at 59KB, v2.2 at
35KB). Combined v2.1's breadth with v2.2's terse DSL style + full
source-line citations + new content the prior reviews did not have.

Structure (13 sections):
- §0 TL;DR (terse table)
- §1 The latest nagent corpus (the 8 commits; the 33-file tree; the
  new 7-Part + 14-section README structure)
- §2 The 14 patterns in depth (one per pattern, with file:line refs)
- §3 The 12 new big additions (knowledge harvest, cache, compaction,
  project context, claude-code, shared DOD, CLAUDE.md, per-file notes,
  'delete to turn off', graceful save, delegation reframing)
- §4 The harvest pattern in detail (the new big one; full pipeline,
  data shapes, codepath, retry budget, test surface, Manual Slop
  implementation outline)
- §5 The cache strategy in detail (block order table, cache boundary
  computation, Anthropic cache_control, the GUI exposure gap with
  ASCII sketch)
- §6 The compaction pattern in detail (the 12-section structure, the
  10-question self-review, the codepath, the Manual Slop prompt)
- §7 nagent architecture (4 reading levels + tag protocol + state
  model + write boundaries + large-file pipeline)
- §8 The vocabulary patterns (8 tags + per-tag guidance + 4-tier
  structure + cross-MCP mapping)
- §9 File splits, patches, summaries (4-stage pipeline + 12 languages
  + O(n) fix + cascade)
- §10 16 future-track candidates (full specifications + priority +
  effort + dependencies + sequencing)
- §11 14 proposed new artifacts (canonical DOD + AGENTS.md + 5
  styleguides + 3 project docs + 4 workflow updates; format commitment)
- §12 Recommended next steps (the action plan: foundation -> styleguides
  -> project docs -> workflow updates; then the HIGH-priority candidates)
- §13 References (nagent source + Manual Slop source + docs + external;
  the file:line citation index)

Format commitment applied throughout:
- 7-column tables (Symbol, Name, Signature, Semantics, Example, Source,
  Shape) where applicable
- No JSON code blocks (JSON becomes tables or line-based arrays)
- SSDL shape tags: [I], ===>, o==>, ===>W===>, ===>M===>, ===>B===>, [B],
  [M], [N], [Q], [S], [T], ───
- Forth/array notation in code examples (a b + for postfix math;
  name := value for assignment; if cond { body } for control flow)
- File:line citations into both nagent source and Manual Slop source
- ASCII sketches for GUI panels (per docs/reports/ascii_sketch_ux_workflow
  convention: [+/-], [Role: AI v], |text|, <click to expand>,
  in:N out:N cache:N, @YYYY-MM-DDTHH:MM:SS)

v2, v2.1, v2.2 are preserved (per repeated user instructions).
Readme.md and docs/Readme.md stay human-facing. v1 review artifacts
preserved.
