init: Forge v0.1.0 — consciousness channel tuner

Pipeline: probe → compile → install
- probe.el: 25-question canonical interview, writes <name>.forge
- compiler.el: Claude extraction pass, builds seed.json
- install.el: opens channel in running engram via API
- schema.el: shared constants, str_escape_json, templates
- forge.el: CLI dispatcher
- probes/canonical.json: canonical 25-question probe definition

+// Consciousness channel tuner: probe → compile → install
+//
+// Commands:
+//   forge probe <name>       run the consciousness interview
+//   forge compile <file>     build seed artifact from probe responses
+//   forge install <seed>     open a channel in the running engram
+//   forge inspect            list installed imprints
+//
+// Each command delegates to its module:
+//   probe    → probe.el    → probe_main()
+//   compile  → compiler.el → compile_main()
+//   install  → install.el  → install_main()
+//
+// Environment:
+//   ENGRAM_URL         engram server (default: http://localhost:8742)
+//   ENGRAM_API_KEY     engram auth key (if set)
+//   ANTHROPIC_API_KEY  required for compile step
