docs: fix stale and incorrect documentation across 18 files

Cross-referenced all 84 docs pages against the actual codebase and
corrected every discrepancy found.

Reference docs:
- faq.md: Fix non-existent commands (/stats→/usage, /context→/usage,
  hermes models→hermes model, hermes config get→hermes config show,
  hermes gateway logs→cat gateway.log, async→sync chat() call)
- cli-commands.md: Fix --provider choices list (remove providers not
  in argparse), add undocumented -s/--skills flag
- slash-commands.md: Add missing /queue and /resume commands, fix
  /approve args_hint to show [session|always]
- tools-reference.md: Remove duplicate vision and web toolset sections
- environment-variables.md: Fix HERMES_INFERENCE_PROVIDER list (add
  copilot-acp, remove alibaba to match actual argparse choices)

Configuration & user guide:
- configuration.md: Fix approval_mode→approvals.mode (manual not ask),
  checkpoints.enabled default true not false, human_delay defaults
  (500/2000→800/2500), remove non-existent delegation.max_iterations
  and delegation.default_toolsets, fix website_blocklist nesting
  under security:, add .hermes.md and CLAUDE.md to context files
  table with priority system explanation
- security.md: Fix website_blocklist nesting under security:
- context-files.md: Add .hermes.md/HERMES.md and CLAUDE.md support,
  document priority-based first-match-wins loading behavior
- cli.md: Fix personalities config nesting (top-level, not under agent:)
- delegation.md: Fix model override docs (config-level, not per-call
  tool parameter)
- rl-training.md: Fix log directory (tinker-atropos/logs/→
  ~/.hermes/logs/rl_training/)
- tts.md: Fix Discord delivery format (voice bubble with fallback,
  not just file attachment)
- git-worktrees.md: Remove outdated v0.2.0 version reference

Developer guide:
- prompt-assembly.md: Add .hermes.md, CLAUDE.md, document priority
  system for context files
- agent-loop.md: Fix callback list (remove non-existent
  message_callback, add stream_delta_callback, tool_gen_callback,
  status_callback)

Messaging & guides:
- webhooks.md: Fix command (hermes setup gateway→hermes gateway setup)
- tips.md: Fix session idle timeout (120min→24h), config file
  (gateway.json→config.yaml)
- build-a-hermes-plugin.md: Fix plugin.yaml provides: format
  (provides_tools/provides_hooks as lists), note register_command()
  as not yet implemented

+Only **one** project context type is loaded per session (first match wins): `.hermes.md` → `AGENTS.md` → `CLAUDE.md` → `.cursorrules`. **SOUL.md** is always loaded independently as the agent identity (slot #1).

 ## AGENTS.md
 
 `AGENTS.md` is the primary project context file. It tells the agent how your project is structured, what conventions to follow, and any special instructions.

-Hermes is compatible with Cursor IDE's `.cursorrules` file and `.cursor/rules/*.mdc` rule modules. If these files exist in your project root, they're loaded alongside AGENTS.md.
+Hermes is compatible with Cursor IDE's `.cursorrules` file and `.cursor/rules/*.mdc` rule modules. If these files exist in your project root and no higher-priority context file (`.hermes.md`, `AGENTS.md`, or `CLAUDE.md`) is found, they're loaded as the project context.
 
 This means your existing Cursor conventions automatically apply when using Hermes.
