Migrate sustainabot from ReScript to AffineScript with stdlib alignment (#204)

## Summary

Complete hand-port of the sustainabot integration layer from ReScript to
AffineScript, followed by a static-review pass to align the code against
the canonical AffineScript grammar and stdlib. This resolves the
migration initiated under issue #148's policy override (2026-05-24).

## Key Changes

### Code Migration (2026-05-24)
- **Main.affine**: Converted webhook intake and dispatch logic;
refactored JSON/Dict operations to use canonical `json::` and `dict::`
module calls; simplified nested match expressions with `unwrap_or`
helper
- **GitHubApp.affine**: Migrated JWT signing and token caching; replaced
`Bytes` type with `[Int]` array representation; refactored string
chaining to explicit intermediate bindings
- **Oikos.affine**: Ported TEA (The Elm Architecture)
model/update/subscriptions; updated type syntax (`Option[T]` →
`Option<T>`, `Array[T]` → `[T]`); added `pub` visibility modifiers
- **Report.affine**: Converted SARIF JSON construction and grade/emoji
logic; updated all `Float::to_string` and `Int::to_string` calls
- **Router.affine**: Migrated HTTP routing DSL; updated method/path
matching; changed `Array[Route]` to `[Route]`
- **Webhook.affine**: Ported HMAC-SHA256 verification and GitLab token
validation; updated `Dict[String, String]` to `[(String, String)]` tuple
list representation
- **GitHubAPI.affine**: Converted REST client with `Http::fetch`
integration; refactored JSON encoding/decoding
- **Analysis.affine**: Ported repository analysis endpoint calls;
updated JSON object construction
- **Config.affine**: Migrated environment variable access and bot mode
parsing
- **Types.affine**: Updated all type definitions with canonical syntax;
added module declaration

### Static Review Pass (2026-05-25)
- **Structural refactoring**: Split `tea/ServerTea.affine` into three
separate files (`tea/Cmd.affine`, `tea/Sub.affine`,
`tea/Runtime.affine`) because the parser has no inline `module Name {
... }` form
- **Stdlib alignment**: Replaced all non-canonical module calls with
`::` syntax (e.g., `Json.stringify` → `json::stringify`, `Dict.get` →
`dict::get`)
- **Type syntax normalization**: Converted all generic brackets from
`[T]` to `<T>` where appropriate; standardized `Option[T]` → `Option<T>`
- **Effect row cleanup**: Removed placeholder effect annotations;
aligned with `{IO}` effect model
- **Documentation**: Added `MISSING-EXTERNS.md` cataloging 20+ unbound
stdlib surfaces (Env, String extensions, Int/Float conversions, Time,
Bytes, Crypto, Base64) that the mechanical migrator must re-bind
- **Baseline update**: Removed 149 deprecated-API findings from
`.hypatia-baseline.json` (all ReScript `.res` files now migrated)

### Documentation & Housekeeping
- **README.adoc**: Restructured with macro TOC; added architecture
diagram; clarified safety-triangle decision logic
- **docs/ARCHITECTURE.md**: New authoritative source of truth for system
pipeline and component roles
- **docs/wiki-source/**: Added 5 wiki pages (Home, Architecture,
Safety-Triangle, Build-and-Run, Bot-Operations) with publication notice
- **MIGRATION-NOTES.md**: Expanded with static-review changes and
structural rework notes
- **CLAUDE.md**: Updated project conventions and architecture summary
- Removed obsolete `llm-warmup-*.md` files

## Notable Implementation Details

1. **Token caching**: Original ReScript `mut Dict` replaced with
`cache_get`/`cache_set` helper functions marked `TODO` for mechanical
migrator to wire to proper state-effect cell (issue #59)

2. **Unbound surfaces**: 20+ stdlib calls documented in
`MISSING-EXTERNS.md` rather than invented as `extern fn` declarations,
