feat(commands): establish Telegram projection contract - #97169

What does this PR do?

PR8 establishes the Telegram projection boundary for the unified slash-command architecture in #96692.

Telegram currently has three platform-specific concerns that must not become a second command authority:

1. the Bot API exposes a bounded native command menu with stricter naming rules than Hermes command identity;
2. Telegram may deliver /command@bot args, while the command plane must authorize and execute the same canonical command as /command args;
3. native command registration is remote state, so a successful write is not sufficient proof that the intended menu actually settled.

This PR isolates those concerns behind three bounded modules. The canonical command catalog remains the semantic authority; Telegram receives an immutable projection of that catalog, normalizes Telegram-specific syntax back to canonical identity, and reconciles native menu state with exact ordered read-back before settlement.

The approach is intentionally dependency-light and independently landable. Current main does not yet expose the merged PR1/PR2 catalog/dispatcher ABIs, so PR8 consumes the catalog object/JSON shape without defining a competing schema or invocation/result contract. When #97143 and #97153 land, the Telegram adapter can compose this seam directly rather than absorbing more command semantics into the existing adapter.

Invariants

• One semantic authority: Telegram projects catalog state; it does not define command identity or execution semantics.
• Stable identity survives projection: non-blank command_id is authoritative; canonical name is the explicit current-v1 compatibility fallback.
• Native omission is not semantic omission: commands excluded by Telegram's native limits or native-name rules remain resolvable through typed command input.
• Addressing is syntax, not identity: /command@HermesBot args and /command args settle to the same canonical command when the bot target matches.
• Unknown slash-shaped input does not become prompt text: command attempts remain typed unknown/invalid outcomes rather than silently crossing into model input.
• Collisions fail closed: duplicate stable IDs, typed tokens, aliases, or sanitized native names cannot select authority by incidental catalog order.
• Remote mutation requires proof: reconciliation advances state only after the exact ordered native payload is observed after a write.
• Scope is part of settlement: a receipt from one Telegram command scope cannot authorize NOOP in another.

Deliberate non-goals

• No edits to plugins/platforms/telegram/adapter.py in this slice.
• No edits to hermes_cli/commands.py.
• No duplicate CommandCatalog, CommandInvocation, or CommandResult ABI.
• No behavior change at production call sites until the catalog/dispatcher slices land and the adapter composes this seam.
• No expansion of an existing godfile; all six added files remain well below the 2,000-line ceiling.

Changes Made

• hermes_cli/telegram_command_projection.py
  • Adds an immutable Telegram projection over one exact catalog snapshot.
  • Preserves catalog order while separating typed bindings from the bounded native Bot API payload.
  • Produces explicit HIDDEN, NATIVE_NAME_INVALID, and NATIVE_LIMIT omissions.
  • Sanitizes native Telegram names without weakening canonical typed resolution.
  • Rejects duplicate stable identities, typed-token collisions, and sanitized native-name collisions.
  • Carries catalog revision plus a deterministic projection fingerprint.
• hermes_cli/telegram_command_normalization.py
  • Classifies Telegram text into typed NOT_COMMAND, KNOWN_COMMAND, UNKNOWN_COMMAND, NOT_FOR_THIS_BOT, and INVALID_COMMAND outcomes.
  • Normalizes /command@bot args and /command args to the same canonical command identity for the addressed bot.
  • Preserves raw arguments while producing canonical dispatcher input.
  • Keeps slash-prefixed paths/code out of command handling and prevents unknown command attempts from falling through as ordinary prompt text.
• hermes_cli/telegram_menu_reconciliation.py
  • Adds deterministic NOOP, ADOPT, and SET planning for one Telegram command scope.
  • Detects catalog revision changes and remote drift.
  • Requires post-write read-back for SET plans.
  • Produces a settlement only when the observed ordered payload exactly matches the desired projection.
  • Rejects cross-scope settlement reuse.
• tests/hermes_cli/test_telegram_command_projection.py
  • Characterizes stable IDs, PR1-shaped catalog compatibility, order, visibility, aliases, sanitization, native limits, immutability, and collision refusal.
• tests/hermes_cli/test_telegram_command_normalization.py
  • Characterizes addressed/unaddressed equivalence, foreign-bot refusal, unknown command typing, path/code non-command classification, and typed fallback for native-menu omissions.
• tests/hermes_cli/test_telegram_menu_reconciliation.py
  • Characterizes adoption, no-op, remote drift, revision change, exact read-back settlement, and scope isolation.

How to Test

1. Run the focused PR8 characterization suite:

   PYTHONPATH=. pytest -q \
     tests/hermes_cli/test_telegram_command_projection.py \
     tests/hermes_cli/test_telegram_command_normalization.py \
     tests/hermes_cli/test_telegram_menu_reconciliation.py

   Expected receipt: 26 passed.

2. Run repository Python validation against the exact head. Hosted CI already executed the full Python test matrix, E2E suite, Ruff enforcement, Ruff + ty differential, Windows footgun gate, macOS-only tests, Windows-only tests, supply-chain checks, attribution checks, and common-ancestor checks successfully.

3. Verify exact-head packaging/system acceptance:

   • CI run 33174052138 — success, including aggregate All required checks pass
   • Docker run 33174051342 — success on amd64 and arm64, including Docker integration tests
   • Nix run 33174051419 — success

4. Characterization points worth checking explicitly:

   • /status@HermesBot Mixed CASE --Flag and /status Mixed CASE --Flag produce the same command identity and canonical input.
   • A command omitted from the native menu because of the Bot API command limit remains a typed known command.
   • foo-bar / foo_bar native-name collisions fail closed instead of depending on catalog order.
   • A successful native-menu write without exact read-back cannot produce a settlement.
   • A settlement for one scope cannot authorize NOOP in another scope.
