Add Kilo CLI to OpenClaw tools.md

[St0rmz1]

Context

Users report OpenClaw says the Kilo CLI is "not available" or
"not found". The kilo binary is baked into the image and
TOOLS.md has a static Kilo CLI section — but TOOLS.md is only
seeded on fresh provision. Existing instances provisioned
before the section was added never got it. There's no dynamic
update like there is for Google Workspace. Fix: add dynamic
injection in bootstrap, gated on KILOCLAW_KILO_CLI.

Changes

1. kiloclaw/controller/src/bootstrap.ts

Add updateToolsMdKiloCliSection(env, deps) following the
updateToolsMdGoogleSection pattern (lines 391-443):

• Add marker constants: KILO_CLI_MARKER_BEGIN () and KILO_CLI_MARKER_END ()
• Add KILO_CLI_TOOLS_SECTION constant with the same content
  currently in container/TOOLS.md lines 9-17, wrapped in markers
• Function logic: if KILOCLAW_KILO_CLI === 'true', append
  section (skip if marker already present). If flag is
  absent/false, remove stale section if present.
• Export the function
• Call it in bootstrap() next to updateToolsMdGoogleSection
  (line 499)

2. kiloclaw/container/TOOLS.md

Wrap the existing Kilo CLI section (lines 9-17) with the same
markers so the dynamic function recognizes it on fresh installs
and doesn't duplicate it.

3. kiloclaw/controller/src/bootstrap.test.ts

Add tests for updateToolsMdKiloCliSection:

• Adds section when KILOCLAW_KILO_CLI === 'true' and marker not
  present
• Skips if marker already present (idempotent)
• Removes stale section when flag is absent
• No-ops when TOOLS.md doesn't exist
