Convert all ASCII diagrams to mermaid with consistent styling
Replace ASCII art diagrams in 9 guide files with mermaid flowcharts
using a unified style system:
- 5 semantic colors (Okabe-Ito derived, color-blind safe):
teal (nodes), sky blue (instances), blue (network),
amber (load balancers), mauve (management)
- classDef for reusable styles, tinted subgraph fills
- Max 2 lines per node, specs in companion tables
- <br/> for line breaks (not \n, which Gitea renders literally)
- Solid arrows for data flow, dashed for control plane
Files converted:
- haproxy-guide.md (1 diagram)
- observability-guide.md (1 diagram)
- api-interception-guide.md (1 diagram)
- incusos-break-fix.md (3 diagrams: partitions, boot chain, updates)
- shared-storage-guide.md (3 diagrams: iSCSI arch, topology, multi-host)
- networking-guide.md (2 diagrams: bridge, OVN topology)
- operations-center-guide.md (1 diagram)
- ovn-deep-dive.md (3 diagrams: lab, bridges, Geneve mesh)
- production-lab-guide.md (1 diagram)
- mermaid-test.md updated as style reference with <br/> fix

Execute break-fix exercises, document results and fix VMIDs
Exercises executed on 2026-02-24:
- Exercise 1 (Update Observation): observed download, A/B switch, DB-leader
transfer during reboot. All 3 nodes updated to 202602240349.
- Exercise 3 (Network Isolation): OVN gateway is SPOF (no failover),
east-west traffic survives, MAC change causes boot hang.
- Exercise 4 (Full Node Failure): 2/3 quorum held, ~20s detection,
~50s recovery, instances auto-restart.
- Exercise 2 (Simulated Failed Update): blocked (no update available).
Fixes: VMIDs corrected from 900-902 to 400-402, added MAC safety rule,
documented Proxmox API --data-urlencode requirement for MAC addresses.

Add IncusOS break-fix guide, incusos-health helper, immutability rules
Phase 4: Explore IncusOS immutability via the /os/1.0 API:
- incusos-health script with --status/--partitions/--tpm/--services/--network/--update
- Validated: TPM encryption (root+swap), Secure Boot with 4 certs, ZFS pool
- Documented A/B partition scheme, update mechanics, security chain
- Defined 4 break-fix exercises (update observation, failed update, network
isolation, full node failure) with safety rules and pickup points
