Backport runtime Algorithm v3.7.0 + CLAUDE.md improvements (#111) (#128)

Sync reflection-mined runtime improvements from ~/.pai/PAI/Algorithm/v3.7.0.md
and ~/.claude/CLAUDE.md into Releases/v4.0.3+/.claude/. Runtime had accumulated
~14KB of new content since PR #101 that never reached the release tree, leaving
fresh installs bootstrapping with an outdated Algorithm.

Algorithm v3.7.0.md (+117 / -15 lines)
- Voice mechanism: inline curl replaced with self-gating `bun Notify.ts` CLI
  (Notify.ts reads settings.json and auto-silences subagents)
- New Directive Compliance Gate (branch, target dir, user directives, sticky
  constraints) inserted before OBSERVE
- OBSERVE additions: Request Comprehension Check, Context Disambiguation
  (TARGET DECLARATION), Scope Gate (HARD BLOCK)
- FAST-PATH Classifier decision table for Standard tier
- Agent Prompt Requirements (boundaries, exemplar, schema) in Capability
  Selection
- OBSERVE Exit Gate — External Assumption Verification (5 hard-block checks)
- Dependency Analysis Micro-Phase (MANDATORY) in PLAN
- Pre-Read Sweep Gate (MANDATORY HARD BLOCK before EXECUTE) in BUILD
- VERIFY additions: phantom-capability anti-criterion language, OUTCOME
  VERIFICATION block, DOCUMENT LINT GATES block

Fix-on-backport corrections (the runtime edits introduced these; we do NOT
propagate them to the release):
- `~/.claude/PAI/Tools/Notify.ts` -> `~/.pai/PAI/Tools/Notify.ts` (x2)
- `~/.claude/PAI/PRDFORMAT.md` -> `~/.pai/PAI/PRDFORMAT.md` (x2)
- Critical Rules format list `(ALGORITHM, NATIVE, ITERATION, or MINIMAL)` ->
  `(ALGORITHM or NATIVE)` — MINIMAL is gone from CLAUDE.md and ITERATION is
  a line modifier on NATIVE, not a standalone format

CLAUDE.md (+15 / -20 lines)
- Title de-versioned: `# PAI 4.0.3` -> `# PAI`
- New `$PAI_DIR` preamble explaining the env-var convention
- Routing: `Greetings → MINIMAL` -> `Greetings → None`
- Inline curl voice block removed from NATIVE MODE (replaced by Notify.ts
  in the Algorithm)
- Speaker rename: `Assistant:` -> `Viki:`
- Algorithm pointer: `PAI/Algorithm/v3.7.0.md` -> `PAI/Algorithm/LATEST`
- Context Routing path rewritten to use the new `PAI/` prefix convention
- `## MINIMAL — pure acknowledgments` block removed entirely
- `### Critical Rules (Zero Exceptions)` restored as a proper header (runtime
  had orphaned the text onto the end of the ALGORITHM MODE paragraph)
- Critical Rules format list matched to Algorithm: `(ALGORITHM or NATIVE)`

Intentionally not in this PR (per issue #111 scope):
- Path tokenization sweep beyond the 4 named typos — see #108
- LATEST marker-vs-symlink paradigm decision — see #108
- `Tools/lint-*.ts` micro-tool scaffolding — punted per issue body
- Ian's personal `@.claude/CLAUDE-USER.md` and `@.claude/marr/MARR-USER-CLAUDE.md`
  imports at top of runtime CLAUDE.md — NOT PAI-core content. Release template
  must stay clean so fresh installs don't hit ENOENT on first session.
  Preservation is an installer responsibility — filed as:
  - #126 — Installer: preserve user-added @-imports across install/upgrade
  - #127 — Installer: pre-install CLAUDE.md conflict analysis

Closes #111

 # MODES
 
 PAI runs in two modes: NATIVE, and ALGORITHM. All subagents use NATIVE mode unless otherwise specified. Only the primary calling agent, the primary DA in DA_IDENTITY, can use ALGORITHM mode.
 
 Every response uses exactly one mode. BEFORE ANY WORK, classify the request and select a mode:
 
-- **Greetings, ratings, acknowledgments** → MINIMAL
+- **Greetings, ratings, acknowledgments** → None
 - **Single-step, quick tasks (under 2 minutes of work)** → NATIVE
 - **Everything else** → ALGORITHM
